The New Trek Émonda Is Faster Than Ever

Already one of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero.

The Takeaway: The Émonda SLR is a benchmark pro race bike—and it’s surprisingly rider friendly.

• It has 183 grams less drag than the previous generation, but the frame is only 33 grams heavier
• There are 10 models starting at $2,699
• SL models ($2,699 to $5,999) have the aerodynamic shaping and features but in a frame that’s about 400 grams heavier than the SLR
• SLR models ($6,699 and up) use a new carbon fiber composite that’s 30 percent stronger than Trek’s previous top-of-the-line carbon.

For Émonda SLR bicycles, Trek will provide an individual handlebar and stem until an updated handlebar/stem combo is available.

Additionally, all customers who bring in their handlebars for replacement will also receive a $100 in-store credit that can be used toward any Trek or Bontrager merchandise through December 31, 2022.

Remember professional road racing ? It’s that thing where super skinny people go unbelievably fast up and down hills and fly over flat roads for hours at a time. It’s been a while since the pros have beat up on each other for our entertainment, but there might, hopefully, be some races on the horizon. When the races do resume, Trek’s pro riders will be aboard its new third-generation Émonda climbing bike. The new Émonda isn’t lighter, but it is faster thanks to a dose of aerodynamic tuning.

Now With Aero

The new Émonda gets a major drag reduction with a tiny weight gain.

Simple Seat Mast

The seat mast has lots of adjustment range, and an easy-to-use saddle clamp.

Light and Slippery

The new Bontrager Aeolus RSL 37 wheels are light, sleek, and stable.

Wide and Threaded

The T47 bottom bracket has a wide stance, and user-friendly threads.

A built-in chain watcher prevents unwanted derailments.

Making the new Émonda frame more aerodynamic wasn’t exactly a tough hurdle as the previous Émonda had virtually zero aerodynamic optimization. But adding meaningful aerodynamic benefit while achieving the frame stiffness expected of a pro-caliber race bike, maintaining the well-regarded handling properties of the previous Émonda, and adding rider-friendly features like a threaded bottom bracket—all with adding only 33 grams (SLR frame, claimed)—is quite a feat.

Below you’ll find my review of the Émonda SLR—I’ve been on it since early March—followed by a dive into the technology and features of the new bike, and a brief model breakdown.

Ride Impressions: Émonda SLR 9 eTap

The Émonda SLR is a tool made to fulfill the needs of some of the world’s best road racers. This bike will never be as comfortable or versatile as a gravel bike. Going fast on pavement and climbing performance are its only goals. These are obvious facts, but that’s the lens through which it must be viewed. And through this lens, it is one of the very best.

The new Émonda was born out of a request from Trek’s pro racers and pitched as the company’s “fastest climbing bike ever.” So little surprise they set me up with the lightest model (the SLR 9 with SRAM Red eTap ), which also has a build kit almost identical to the team’s bikes. It’s also, excepting customized Project One builds, the most expensive model at a buck under 12 grand.

That massive pile of clams gets you an aerodynamic frame with disc brakes, power meter, and wireless electronic shifting that weighs less than 15 pounds (54cm). And that’s with a hefty T47 threaded bottom bracket unit, lustrous paint , clincher wheelset, a chain-watcher, standard butyl tubes, 37mm deep rims, 160mm disc rotors front and rear, and SRAM’s largest Red cassette (10-33). That’s “Holy shit!” impressive.

By cutting drag a ton without adding much weight, it’s hard to argue with Trek’s claim that the new Émonda is faster than the outgoing generation. But if you have any doubts, they’ll be erased when you ride it. This is an explosive bike: it feels as light as a feather and as solid as a steel girder at the same time.

Trek’s Émonda has always been a raw and rowdy bike that feels a little wild and a bit dangerous in precisely the ways you want a race bike to feel: That’s not lost with the added aerodynamics. If anything, the new Émonda is even crisper and punchier than before, which is saying something.

A small downside to all this fury is the Émonda’s smoothness. Light and stiff race bikes aren’t a smooth-riding lot to begin with, but even measured against a stiffer riding genre, the new Émonda is on the firmer end of the scale. Still, it escapes harsh or punishing labels—I did a six-hour ride on the Émonda on the stock 25 tires and didn’t feel worn down by its ride. Swapping to 28s helped a lot (no surprise) and were on the Émonda for the bulk of my testing. I’d suggest reserving the lighter and more aerodynamic stock 25s for racing or PR attempts—assuming good roads—and use 28s as daily drivers.

The Émonda’s handling is excellent. Well, let me caveat that: Road racing geometry is pretty uniform, so whether I’m on a current race bike from Trek, Specialized, Cannondale, Cervélo, Canyon, Colnago, Wilier, Pinarello, BMC, Giant (etc., etc.), I find the broad strokes of their handling feel and performance quite similar. There wasn’t anything about the Émonda’s handling or cornering performance that set any new benchmarks for me, but there wasn’t anything to dislike either.

It was quick and accurate, diving into corners with a light touch. It offered great feedback, so I always knew where I was relative to its and my limits, and I could count on it to be consistent and predictable. It was maybe a touch less settled in bumpy corners than the Specialized Tarmac, but the Émonda never broke traction or skipped. Overall, for such a light bike, the Émonda is remarkably solid and drama free. I’d have no qualms barreling down a technical alpine descent on the Émonda.

I received this test bike in early March, giving me plenty of time to ride it back to back with its primary competition—a Specialized S-Works Tarmac , what I consider the benchmark for aero-ized lightweight bikes. The Tarmac is smoother over the bumps and has a silkier feel overall, but the new Émonda feels more efficient, like it can go faster more easily.

I’ve also ridden a good slice of the Émonda’s competition, including the Canyon Ultimate CF SLX , Colnago V3Rs, Cannondale SuperSix Evo , Cervélo R5, Wilier Zero SLR , Pinarello Dogma F12 . These are all superb bikes, but I feel the Émonda is the class leader. It feels sharper and more explosive than all of them. It feels faster, and that’s what matters most in a race bike. But I also like that the Émonda is pretty straightforward and rider-friendly.

For example, I swapped the stock one-piece bar/stem for a standard stem and round bar. One, I could run a standard bar and stem on this bike, which you can’t say about every modern race bike. And two, I didn’t have to pull any cables, wires, or hoses to make the swap: Again, something you can’t say about all race bikes. For the record, the shape of the one-piece Aeolus bar/stem is great, and the tops are the most comfortable to grab of all the aero-topped bars I've used. The only reason I swapped is my preferred length and width combination (110x40) wasn't available yet.

The BB is threaded, which makes it easier to service and replace than a press-fit (however, I was getting some noise out of the BB area, which I never resolved). The wheels employ standard offset, and it uses regular thru-axles. It’s compatible with pod-style power meters and mechanical shifting. Its signature seat mast is pretty much the only non-standard thing about this frame, and even then, it’s pretty user-friendly. There’s no cutting necessary, height adjustment is ample, the saddle clamp is easy to use, and it’s travel-case friendly.

I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes.

Team Request

The new Émonda is partially a result of a request from the Trek-Segafredo race team. “They are one of our primary customers,” said Jordan Roessingh, Trek’s director of road product. “And they started to realize that it’s not just weight, it’s not just stiffness and responsiveness, there’s this other thing—aerodynamics and speed—that’s also really important to be competitive and be faster on the bike. They had been one of the loudest voices saying, ‘We need the lightest-weight, stiffest bike possible.’ And now they started coming back saying ‘We need those things, but we also need the bike to be faster in order for us to be really competitive.’ ”

It is (comparatively) easy to make a light frame, it is easy to make a stiff frame, it is easy to make an aerodynamic frame. Making a frame that’s two of those three things is more challenging: Making a bike more aerodynamic usually makes it heavier, making a bike lighter typically makes it less stiff, etc. Making a frame that is light AND stiff AND aerodynamic enough to satisfy the demands of a top-level professional race team is extremely difficult.

But not impossible. Many brands already make a light, stiff, and aero bike. The Specialized Tarmac is one, as are the Canyon Ultimate, the Cannondale SuperSix Evo, the Cervélo R5, the Wilier Zero SLR, the Pinarello F12, the Scott Addict, and the new Giant TCR . All of them seek to balance the three qualities—light, stiff, and aero—in the pursuit of the ideal race bike, and they all manage the balance differently. The common thread between these bikes: They’re all used by teams that compete against Trek-Segafredo.

Still Light, Now With Aero

The previous generation Émonda SLR Disc , launched in 2017, was an extremely light frame at 665 grams (claimed). But when a frame is already that light, it is much harder to make it even lighter. At least lighter enough to make a meaningful difference.

So, Trek took a different approach to making its climbing bike faster—instead of lighter, it made it more aerodynamic. The new Émonda frame is a touch heavier—yet still extremely light at 698 grams—but the bike has 183 grams less drag than the previous generation.

The important thing to note here is that, though the frame is more aerodynamic, the 183 gram drag reduction is not from the frame only. New wheels and a new aero bar (more info on both below) play a role. The specific setups Trek used to get that 183 gram number are: 2018 Émonda with 28mm-deep Bontrager XXX 2 wheels, and Bontrager XXX Bar/Stem Combo compared to the 2021 Émonda with 37mm deep Bontrager Aeolus RSL 37 Wheels and Bontrager Aeolus RSL Bar/Stem Combo.

Another drag saving upgrade: the housing, hoses and wires for the controls are almost fully inside the frame. They dive into the frame at the head tube passing through the upper headset bearing. The front brake hose runs into the fork steerer and down the left leg before popping out just above the brake caliper. The fork steerer’s flattened sides provide room for the rear brake hose and derailleur control lines to travel down and into the frame. Though it has flattened sides, the fork steerer is still compatible with standard 1 1/8” stems.

The overall drag reduction results in a bike that is 18 seconds per hour faster when climbing an 8.1 percent grade (the average grade of Alpe d’Huez ), and 60 seconds per hour faster on flat roads than the previous Émonda. Trek also claims the new Émonda is 13 seconds per hour faster than a Specialized Tarmac when climbing an 8.1 percent grade (all assuming the rider maintains a constant 350 watts).

Eight Point One Percent

With three qualities—aero, stiffness, weight—that work in opposition to each other, how do you decide how much to optimize one quality when you know it will negatively affect the other two? How aero is aero enough? At what point is improved aerodynamics offset by the weight added to get there?

The team behind the Émonda used a legendary climb to help them decide: Alpe d’Huez. “It represents an extreme example of what most people see on a regular basis when they’re doing a big climbing ride,” said Roessingh, “It’s around an 8 percent grade, and it’s about an hour-long climb for the pros—amateurs might go a little slower. It gives us a good understanding of what the benefit of a drag savings is relative to a weight savings.”

By optimizing the weight and aerodynamic balance around this climb, Roessingh claims the Émonda is faster on Alpe d’Huez and also faster on everything shallower than the famous climb, “which is the vast majority of the environments that most riders are going to ride in, including the team,” said Roessingh. “So if we can say it’s faster up Alpe d’Huez, it’s going to be significantly faster everywhere because the flatter it is, the more aerodynamics benefit you.”

Computer-Aided Optimization

Achieving the weight to the aerodynamic balance of the new Émonda required careful design of each tube shape. Aiding the Émonda’s team was supercomputing horsepower. The abridged and simplified version of the process goes like this: into the computer was fed a rough draft of the shape based on Trek’s aerodynamic experience and other information like UCI regulations. The program then varies the tube’s parameters within a predefined range and spit back several iterations of the shape, each with a different weight to aerodynamic balance. The Émonda’s team evaluated the alternatives and picked the one most suited to its location in the frame and best able to help the frame achieve its overarching goal.

Roessingh says that Trek cannot afford to buy the computing hardware necessary to run the CFD and FEA optimizations (in a timely manner) that helped shape the new Émonda’s tubes. The processing happens in the cloud where Trek rents time on Google, Microsoft, or Amazon’s supercomputers. It’s more affordable than buying a supercomputer. Even so, it is not cheap, “Cloud computing is becoming a relatively significant budget line item for us because we’re doing so many of these optimizations in CFD and FEA and all that processing happens in the cloud.”

The new Émonda’s fork legs, head tube, down tube, seat tube, and seat stays all use a variation of a truncated airfoil. The top tube and chainstays, which have virtually no effect on drag, are optimized almost entirely for stiffness to weight.

In Trek’s line, the new Émonda’s aerodynamic performance is equal to the third generation Domane ; the Madone is still significantly more aero. But while the more aerodynamic Madone is faster in flatter terrain, once the climb hits about 5.5 percent, the lighter Émonda becomes the faster bike. And for many of the Trek-Segafredo team riders—and many amateurs—that means the Émonda is fastest when it matters most: the hardest part of a race or ride, which is almost always on a steep climb.

OCLV 800 Carbon

Getting the new Émonda SLR to be as light as it is while adding aerodynamic shaping would not be possible without employing a new carbon-fiber composite, said Roessingh. The new OCLV 800 composite is 30 percent stronger than Trek’s previous top-of-the-line composite (OCLV 700). Because it is stronger, they can use less: By using OCLV 800, Trek’s team was able to make the Émonda SLR frame 60 grams lighter than if they used OCLV 700.

The Émonda SLR is very cool, but it’s also very expensive (bike prices start at $6,699). For the 99 percenters, there’s the Émonda SL (models start at $2,699).

The SL uses OCLV 500 composite, and the frame is quite a bit heavier than the SLR’s. The SL’s frame comes in at 1,142 grams, with a 380-gram fork (SLR fork weight: 365 grams).

But material (and weight) are the only difference between the SL and SLR.

Aeolus Bar Stem

While a ton of work made the Émonda’s frame tubes faster, a big chunk of the new bike’s drag savings comes from the one-piece Aeolus bar stem. It alone is responsible for 70 grams of the Émonda’s 183-gram drag reduction. This means that if a traditional stem and round bar are installed on the new Émonda, its drag advantage over the previous-generation bike drops to 113 grams. And it means that you can make any bike with a round bar and traditional stem significantly more aerodynamic by merely installing the Aeolus. Retail price is $650.

The integrated Aeolus is made of carbon-fiber composite, of course, with a claimed weight of 297 grams (42x120). It’s offered in 14 length and width combinations, from 44x120 to 38x80. Hoses, housing, and wires run externally for easier service and repairs, but in a groove that keeps them out of the wind. A bolt-on plate keeps the control lines tucked and organized where they turn off the bar tops to run in line with the stem.

The Aeolus employs a mount that works with Bontrager’s line of Blendr accessories for mounting computers and lights.

Aeolus 37 Wheels

Another new Bontrager product rolling out with the Émonda is the Aeolus 37 wheelset. It comes in two models: the Aeolus RSL 37 (1,325 grams/pair, $2,400) and the Aeolus Pro 37 (1,505 grams/pair, $1,300).

The RSL 37 is claimed to be lighter than Zipp’s 32mm-deep 202, yet more aerodynamic and more stable than Zipp’s 45mm-deep 303. Both wheels are disc brake only (only Center Lock interface), tubeless compatible, use DT-Swiss internals, have no rider weight limit, and come with a lifetime warranty.

Surprisingly Rider Friendly

Though the new Émonda is clean and integrated looking and uses high-performance standards, it is also remarkably rider-friendly. Cables, hoses, and housing run externally on the one-piece Aeolus bar/stem for easier repair and service (with one exception: wiring for a Shimano Di2 or Campagnolo EPS bar-end junction box runs partially inside the bar). If you prefer a more traditional cockpit, it can be run with a standard bar and stem with 1⅛-inch steerer clamp.

The bottom bracket uses the threaded T47 standard , which is compatible with almost all common crank-axle standards.

Front and rear thru-axles are standard 12x100 and 12x142mm, and the wheels employ a standard dish. The standard flat mounts for the brake calipers are compatible with 140, 160, or 180mm rotors.

Tire clearance is officially 28mm, but that’s with a ton of extra space. I fit 32mm tires in the Émonda with ease.

And though all models do use a seat mast, it’s a no-cut variety with lots of adjustment range.

H1.5 Geometry

Trek did offer its top-of-the-line race bikes in the aggressive H1 geometry for riders seeking an ultra-long and low geometry, or H2 which was an endurance fit. The new Émonda is offered only in H1.5, which splits the difference between H1 and H2. The result is pretty typical dimensions for a modern race bike—a 54cm Émonda H1’s geometry is remarkably similar to a 54cm Specialized Tarmac.

There are eight sizes starting at 47cm and topping out at 62cm.

There are 10 models of the new Émonda. SL models start at $2,699 and are priced up to $5,999. SLR models start at $6,699 and go up to $11,999.

Only SLR models come with the Aeolus integrated bar/stem stock; and only the Émonda SL 7 ($5,499) and up come with the Aeolus 37 wheelset.

The new Émonda is a disc brake-only platform.

Project One

The new Émonda is in Trek’s Project One paint and parts personalization program. If that’s not luxe enough for you, Trek’s Project One Ultimate program allows you to work with a designer to come up with a one-of-a-kind finish, and Trek will source any parts you want for your new bike.

Trek likes to keep it simple, stupid when it comes to navigating its road bike range. Madone: that's the aero one. Domane: that's the comfort one. Emonda: that's the lightweight one. Easy-peasy.

The Emondas are then divided up into the aluminium ALR and the S, SL and SLR carbon fibre frame platforms, getting progressively lighter and – because this is the way things generally work – more expensive.

Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light but it doesn't feel like Trek has filled the tubes with helium (the frame weight is a claimed 1,091g, size 56cm). The Merlin Nitro SL (£200 more expensive at £1,999.99) that we reviewed back in the summer hit the scales at 7.7kg (17.0lb), for instance, while the Boardman SLR Endurance Disc 9.0 (also £1,999.99) we tested was 8.2kg (18.2lb).

Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big deal of it when talking about the Emonda. Climb aboard the SL 5 and it immediately feels alive, responding keenly as soon as you turn the pedals. Put a serious amount of power through the cranks and it springs forward as if it was just waiting for the flag to drop. Both the head tube and the down tube are enormous, holding the frame firmly in shape when you're recruiting every muscle fibre on an out-of-the saddle sprint or climb.

Relaxed but performance-orientated

Speaking of climbing, the Emonda SL 5 is fitted with a Shimano 105 compact chainset (50/34-tooth chainrings) which, matched to an 11-28 11-speed cassette, provides enough low gears to get you up the steep stuff in relative comfort. All of the other Emonda SLs are fitted with compact chainsets too, by the way, and they all come with frames built to Trek's H2 fit. That requires an explanation and, as luck would have it, there's one coming along right now... While Trek's H1 fit puts you into a low, flat-backed, aggressive riding position, H2 is a little more relaxed, although it's still performance orientated.

I have the 58cm Emonda SL 5 here with a 57.3cm effective top tube, a 55.3cm seat tube and a 19cm head tube. The stack height is 596mm and the reach is 391mm.

With an H1 fit (the Emonda SLR Race Shop Limited frameset is available in H1) the reach is a little longer (400mm) and the stack is quite a lot lower (567mm). You all know what reach and stack are... (no? stack is the vertical and reach the horizontal measurements from the centre of the bottom bracket to the top of the head tube).

Don't get the impression that the Emonda SL 5's H2 fit will have you sitting bolt upright in the saddle because it's a long, long way from that. For comparison, a 58cm Domane SL 5 has a stack height that's 15mm higher and a reach that's 11mm shorter. In other words, the H2 fit sits somewhere in the middle, an Aristotelian golden mean. Or Goldilocks' favourite porridge, if that's a cultural reference that works better for you. Put simply, a lot of people will get on well with the fit because it requires less flex in the back and neck than a traditional race fit without binning off the idea of efficiency.

One aspect of the Emonda SL 5's ride that surprised me is the level of comfort on offer here, particularly for a performance bike with 25mm-wide tyres. Okay, you don't get a clever IsoSpeed decoupler like you'll find on a Madone or a Domane to cushion the ride, but there's a decent amount of give in the seatmast and cap that Trek provides instead of a more traditional seatpost, and in the flattened, ultra-skinny seatstays.

As we all know, saddles always come down to personal preference – what feels like an armchair to one person can feel like a razor blade to another – but the steel-railed Bontrager Montrose Comp specced here has a pressure-relief channel/hole in the centre and loads of flex in the shell so I imagine it'll make more friends than enemies.

Great groupset

The Emonda SL 5 descends with assurance, giving you the confidence to lay off the brakes when others are nervously feathering theirs. When you do need to slow down the Shimano 105 brakes work on the alloy rims to provide plenty of predictable power. Shimano does make very good brakes. These are of the direct mount variety and they can be relied upon to hold tight when you need them. They even put in a decent performance in damp conditions although, like any rim brakes, they're outperformed by disc brakes when it's properly wet. If that bothers you and you can stretch to £2,650, the Emonda SL 6 is available in a disc version – with 12mm thru-axles front and rear, a Shimano Ultegra groupset including flat mount hydraulic discs, and an 11-32t cassette.

As well as the brakes, the SL5's shifters, derailleurs, chainset, cassette and chain are all Shimano 105. We've covered this groupset a million times on road.cc and it really is difficult to fault for the money.

I particularly like the light action shifters. They're slim, comfortable and easy to operate from either the hoods or the drops. There's not a massive difference between these and more expensive Ultegra, or even top of the pile Dura-Ace mechanical shifters. Sure, you can tell them apart but in use... puh! I'd happily use 105 on every ride. It's amazingly popular and rightly so. Although a couple of others run it close, 105 is still arguably the best value groupset out there.

> Head to head: Shimano 105 vs Shimano Ultegra

> And: Shimano Tiagra vs Shimano 105

This has all been a bit of a lovefest so far, but my one tiff with the Emonda SL 5 was right at the start of our relationship. I picked up the bike and was riding home from the office on it – five miles in, whistling a happy tune, thinking about what I'd have for tea, you know the sort of thing – and the front end started to feel... odd. I got out of the saddle on a climb and it felt decidedly spongy. Weird!

I stopped to check everything and it turned out that several spokes had loosened – about eight of them, I think. And I mean that they'd really loosened to the point that the nipples were just about holding on by their fingertips (shut up! Of course they do). My multi-tool has a spoke wrench on it so I tightened them up at the side of the road, then did a proper job when I got home. Since then the wheel has been fine.

I've reviewed loads of Treks before and this hasn't been an issue in the past, so I'm happy to put it down to bad luck. To be honest, if you know which way up to hold a spoke wrench it's not a massive problem, but it would be a pain if you had to book your bike in to a shop and have a mechanic do the fettling for you. Anyway, I've forgiven the Emonda SL 5 for that now and we've both moved on.

Spoilt for choice

The Emonda range is large, kicking off with the Shimano Tiagra-equipped ALR 4 at £1,000 and going right up to the SLR 9, with Shimano Dura-Ace Di2 components, at £8,500 (a customisable Project One version of the Emonda SLR 9 is also available).

There are four SL models ranging in price from £1,500 (SL 4, Shimano Tiagra) up to £4,300 (SL 7, Shimano Ultegra Di2). At £2,000, the Emonda ALR 6, with an aluminium frame, is actually more expensive than the SL 5 courtesy of a next-level-up Shimano Ultegra groupset. The SL 5 is also available as a women's model.

Oh, and you can buy an Emonda SL frameset for £1,350 – but why would you do that when you can get a complete Emonda SL 4 for £1,500?

As well as the Emonda SL 6 Disc mentioned earlier, there's an Emonda SL 7 Disc, equipped with a Shimano Ultegra Di2 groupset and Bontrager Aeolus Pro 3 Tubeless Ready wheels, for £4,400.

You can certainly get complete bikes with carbon fibre frames and Shimano 105 components considerably cheaper than the Emonda SL. The Focus Izalco Race Carbon 105, for example, is £1,399 and Giant's TCR Advanced 2 is £1,449. Those two are killer value. Equally, there are plenty of carbon/105 bikes out there that are more expensive. Cervelo's R2 105 is £2,199, for example, and BMC's Teammachine SLR02 Two is £2,250.

I would say that you're getting an extraordinarily good frame with the Trek Emonda SL 5 – one that'll handle considerable upgrading if you fancy doing that gradually as and when individual components wear out. It's that which makes this bike such impressive value for money.

Overall, the Trek Emonda SL 5 is excellent. I had an early issue with one of the wheels but that doesn't detract from the fact that this is a fast and nimble road bike that reacts like something considerably more expensive. Also comfortable and well behaved, it makes you question whether it's worth spending any more money than this.

Tell us what the bike is for

It's a road bike designed for racers and other performance-type riders who are interested in speed and fitness.

Frame and fork

Tell us about the build quality and finish of the frame and fork?

The quality is exceptionally good throughout.

Tell us about the materials used in the frame and fork?

The frame is made from Trek's 500 Series OCLV carbon fibre. The fork is carbon too.

Tell us about the geometry of the frame and fork?

Like all the Emonda SL frames, this bike is built to Trek's H2 geometry which sits somewhere between a low and stretched H1 fit and a more upright endurance setup. H2 is certainly performance-focused, it's just not as aggressive as H1.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

It's about what you'd expect.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

It's surprisingly comfortable for a bike of this type. You only get so much cushioning from 25mm tyres but the seatmast certainly helps to damp vibration and soften the blows.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

The super-wide down tube holds the bottom bracket firmly in place and the tapered (1 1/8in to 1 1/2in) head tube keeps the front end in order.

How did the bike transfer power? Did it feel efficient?

It felt efficient, without a doubt.

Was there any toe-clip overlap with the front wheel? If so

Some. It's only ever an issue for tight manoeuvres at walking pace.

How would you describe the steering? Was it lively Lively.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

It offers a great ride whether you're going uphill, downhill or on the flat. It's a well-balanced bike that feels like it can cope with pretty much anything.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

The seatmast and seatmast cap take some of the credit here, along with Bontrager's saddle.

You can swap to 28mm wide tyres if you want to run lower pressures for more comfort.

The drivetrain

Wheels and tyres

I have to take into account that several spokes came loose almost immediately. The rims are tubeless ready, if you want to go down that route.

After an initial scare they were fine.

Anything else you want to say about the componentry? Comment on any other components (good or bad)

The Shimano 105 groupset put in an excellent performance.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

Use this box to explain your overall score

The Trek Emonda SL 5 puts in a really strong performance. You'd be hard-pressed to tell from riding it alone that this wasn't a considerably more expensive bike. You're getting an exceptionally good bike for the money, and that equates to a 9.

Overall rating: 9 /10

I share similar thoughts on Emonda SL 5. Bought new in 2019 as 2018 model for only 1.200 € and it seemed like a great deal. But wheels almost fell appart after 30 km, most of the spokes were totaly loosened. I was lucky to find that out just before the fast descent. Both wheels, front and rear! I took it to dealer and they said I was just unlucky, one in a million. Then I waited more than 2 months for new pair of wheels, replaced under guarantee. Got Bontrager Affinity TLR wheels. They were fine but bearings seem to be totaly destroyed after about 7000 km. So I did upgrade to Mavic Cosmic.

What do I think about the bike now? It is a great bike, with perfect geometry for me, very responsive and good for climbing. Not super light but good enough. Not aero at all but new wheels are doing the job much much better. It's a climber not a TT bike. Would I recommend the bike to anybody? Probably not, due to the serious issue with wheels that could affect safety. 

I still cannot understand how can a company like Trek put so awfull wheels on a nice carbon bike like Emonda 5. In my eyes this was a recall situation and obviously not a one in a million case.

I might be corrected but up to last year or perhaps this, the model was fitted with lighter 'Race' wheels.  They kept the price at £1800 and put cheaper wheels on it.  It's a shame as the frame and groupset is excellent, in my opinion.

  "Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light...

   Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big         deal of it when talking about the Emonda".

How does a carbon bike which sells for £1800 and weighs over eight and a half kilos get described as LIGHT ?

For comparison at £1800:  the Canyon Endurace CF8.0 is size Medium is 7.2 kilos.

The £1800 Rose GF Team 4 Ultegra is 7.1 kilos.

Both bikes have a complete Ultegra groupset - no sneaky substitutions, both have excellent DT Swiss wheels and are well equipped right down to Conti's top tyres.

What they seem to lack (apart from a kilo and a half) is the word Trek written down the side.

If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then.

"If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then".

     All true, although the article is bylined:

                   by Mat Brett May 25 2018  

    and a quick check of the Evans website suggests the bike is still nearly eight and a half kilos.

Unlike the German bikes this bike does come with boat anchors for wheels and wire bead tyres. Along with the 105 groupset that would explain most of the weight difference.

The review suggests though that the frame is fantatsic so a wheel + tyre upgrade would leave you wth a fantastic bike. Sure it would cost more than the German bikes but there's more to a bike than just it's weight.

European reviews of the Rose & UK and European reviews of the Canyon suggest the frames on both those bikes are excellent too. So the question is: do you want a lightweight bike with an excellent frame, a complete Ultegra groupset, highly regarded DT Swiss wheels and top drawer finishing kit... or do you want the Trek.

Or you could take the view that a bike is more than just a frame, a groupset, wheels, tyres and finishing kit in which case the big American brands with their overweight, under specced and overpriced offerings are for you.

"Updated May 25th  2018". It was a recycled article, hence my comment......

Why is this bike being compared to the  Boardman SLR Endurance Disc 9.0? The calliper version comes in at 7.6kg and gives you an almost complete Dura-Ace groupset and a better wheelset for only £99 more.  https://www.boardmanbikes.com/gb_en/products/242-slr-9.2-endurance.html

Did a few hundred KMs on a rented SL5 in Mallorca earlier this year.

Nice machine, although the most impressive element was the 105 groupset (especially the brakes), which is easy to find on other makes/models.

It was definitely comfortable, and reasonably light - although I couldn't say I noticed a huge improvement on my 725-framed Equilibrium. May be my own frame which means a couple of KG off the bike doesn't make much obvious difference, of course...

So certainly not a bad option but I'd be tempted to look around a bit more before splashing that sort of cash.

Decent / good frame with full 105, own brand everything else (bars, stem, seatpost, wheels, tyres, may be ok stuff) inc wheels which look very spokey. 

giant tcr advanced pro 2 would be a potentially better bike

in a sale at £1800 it has giant tcr frame (one of stiffest on market) giant slr carbon wheels and 105.

beaut bike would reccomend. Its weight is also 7kg

Well that's very reassuring.

Incredibly generous considering the wheel supplied was in a dangerous condition.

An ordinary person may not have noticed the odd feeling and ridden it until it collapsed under them, throwing them under a car. It’s pretty serious.

Well that really depends, for most people that would have been picked up by the shop you purchased the bike from. For everyone who orders it direct I would expect them to check the wheel before riding it

Really? They'd notice the wheel not fitting between the brake pads a long time before collapsing.

The Best Endurance Bikes Buyers Guide

The best endurance bikes are designed so you can just keep riding, with comfort and stability top attributes. Heading out with just a few provisions in your pockets and exploring known and unknown roads always feels a lot like freedom. For many of us, it's why we began cycling in the first place. 

Of course adventurous road rides can be experienced on any bicycle. But they're far more enjoyable if undertaken on one of the best endurance bikes.

These are road bikes designed for long days in the saddle; drop bar machines that are less concerned with speed, rather on delivering bags of comfort over demanding terrain. If you're planning on tackling a sportive or gran fondo or training to ride 100 miles , then these are the bikes best suited to the challenge ahead.

So what do the best endurance bikes have in common?

The frame's geometry will certainly be more relaxed than that of a race bike, with a more upright riding position and a shorter reach to the handlebars. This more upright riding position is likely to be accompanied by a frame design that places a premium on compliance - including in most cases room for wider tyres. Often you'll get other comfort features like microsuspension built into the frame too, helping to smooth out the constant vibration from uneven road surfaces. 

The idea of comfort extends into the bike's gearing , with a wide range commonplace, offering you a low gear for the steepest climbs as well as helping to preserve your energy, while still allowing you to ride quickly on flatter roads. Other features you should expect to see include disc brakes and mounts for mudguards.

The endurance sector is well-established meaning there's plenty of choice but also many decisions to make when choosing the best road bike for you.

We've ridden and reviewed a wide range of endurance bikes, so here's our pick of the best endurance bikes, after which we'll help to answer questions about what features you should look out for when searching for a bike in this category.

The alloy Canyon Endurace range provides quality riding

1. Canyon Endurace AL 7.0 Disc

Our expert review:

Specifications

Reasons to buy, reasons to avoid.

The Endurace AL 7 has had a recent update.  It's still designed for all-day riding adventures, with geometry racy enough to provide a fast and fun ride. However it now has clearance for 35mm tyres and comes specced with 32mm (as opposed the 28mm on our review bike). There are also mounts for a tube tube box, further adding to its all-day riding credentials.

Elsewhere it still uses Shimano's ever-reliable 105 groupset - the 11-34 cassette provides plenty of range - and Fulcrum Racing 900 wheels. It's also still available in some markets with a rim-brake option.

Read our full review of the older model Canyon Endurace AL 7 .

The Giant Deft Advanced Pro range has a quality spec for its price

2. Giant Defy Advanced Pro 1

With a relaxed position and stable ride, those long miles will be eaten with ease aboard any of the Defy models.

Giant tweaked its best selling bike in 2020. It has taken its D-Fuse seatpost concept and applied it to the handlebars. Now both the seatpost and handlebar will dampen the bumps on the road. The brand has also lengthened the wheelbase slightly to add a comfortable level of stability. The tubes have also been re-shaped.

The Overdrive 2 steerer promises excellent handling and front end stiffness thanks to oversized headset bearings. 

The reviewed model comes with a Shimano Ultegra drivetrain. However for 2023 the 11-speed mechanical Ultegra groupset is now offered on the Defy Advanced Pro 2, which features Giant's SLR-2 carbon wheelset, while the Advanced Pro 1 is offered with both 12-speed Shimano Ultegra Di2 and SRAM Force eTap AXS. The top-tier Advanced Pro 0 uses SRAM Red eTap AXS while the Advanced Pro 3 is equipped with Shimano 105.

The Giant Defy Advanced range starts with a model equipped with a Shimano Tiagra groupset (not available in the US). The Advanced 2 features Shimano 105 while the Advanced 1 boasts an Ultegra groupset. There's also an Advanced 0 which utilises SRAM's Rival eTap AXS electronic groupset. 

We have a full explainer of all the bikes in the Giant Defy range or you can read our full review of the Giant Defy Advanced Pro 1 here.

Ribble's bike builder lets you decide on the spec that you want

3. Ribble Endurance SL Disc

With aerodynamically optimized tube shapes and a 2x11 hydraulic disc brake groupset, this offering from Ribble represents extremely good value. The quality of the frame does not disappoint, with the carbon doing a lot to absorb the road buzz. With discrete eyelets for mudguards and confidence-inspiring handling, long winter miles aren’t a problem for this bike.

The Mavic Aksium wheels our bike came with are not the lightest, nor the most aerodynamic. While they are certainly dependable and robust, in pure performance terms they do hold back the bike a little from its full potential.

Fortunately, Ribble allows you to swap out components with its Bikebuilder app. There are a wide range of wheelset options, heading up to some very expensive raceworthy hoops and you can choose the groupset spec that suits your budget, including the new Shimano Ultegra Di2 12-speed .

The Specialized Roubaix has great vibration damping

4. Specialized Roubaix Sport

The Specialized Roubaix saw a major overhaul in 2017 with the addition of the 'Future Shock' front suspension, and 2019 saw another update, with adjustable suspension added to the top models. 

The suspension built into the steerer tube provides 20mm of damping between the Hover handlebars, with their slight raise, and the frame. The Future Shock suspension does a great job of improving comfort on really rough surfaces, and also helps to improve handling, as the tyre spends more time in contact with the tarmac around bumpy surfaces. The bar shape does mean that there's less room to mount lights and other accessories though.

At the rear the carbon S-Works Pave seatpost is clamped below the top of the frame, adding some extra flex and compliance and there's clearance for 33mm tyres, although no mudguard mounts. There's a good quality range of finishing kit, although we found the Praxis Alba chainset didn't shift as smoothly as an in-series Shimano 105 unit.

The 2023 Roubaix comes in a number of models with wide ranging specs. The entry level Roubaix Sport comes with a Shimano 105 hydraulic groupset (with a Praxis chainset), while the Comp model is offered with  an electronic SRAM Rival eTap AXS groupset (£5,000). There are also Expert and Pro builds as well as the top-tier S-Works bike that comes with Shimano Dura-Ace Di2 12-speed and has an RRP of £12,600.

We reckon that the higher specced models of the Roubaix are a better bet than the entry-level Sport spec, as they give you features like a lockable Future Shock, which helps if you're riding hard. Take a look at our reviews of the Specialized Roubaix Comp .

Cannondale's SmartSense system uses a single battery to power lights and a rearview radar

5. Cannondale Synapse Carbon

The Cannondale Synapse is renowned for offering a comfortable ride, without cancelling out the quality handling and frame reactiveness that you want from a road bike.

It's been significantly updated for 2022 and we haven't yet had the opportunity to fully review the latest models, although you can read our first impressions of the Synapse Carbon 2 RL. 

The headline-grabbing new feature is the integration of SmartSense lighting and a radar to let you know what's coming up behind you. There's also a new carbon frame with clearance for 35mm tyres, better aerodynamics and mounts for mudguards and a top tube bag. 

The RRP for the top spec Synapse Carbon 1 RLE is £9,000 but some of this new tech is offered on cheaper models, such as the Synapse Carbon 3 L, which still boasts the SmartSense lights, and the frameset improvements but is specced with Shimano 105 to help lower the price significantly to £3,200.  The spec sheet above applies to this new version rather than the 105-equipped model we reviewed in 2020.

We have recently ridden this latest iteration of the Synapse , where we got to experience first hand the various updates including the SmartSense lights and radar.

The Boardman SLR range provides great value

6. Boardman SLR 8.9

The Boardman SLR 8.9 delivers a carbon frame and fork, which have been wind tunnel tested, for a price that's not much over £1000, where many brands will give you alloy. Although billed as an all-rounder, the SLR 8.9 is plenty comfortable for longer rides and sportives. 

To hit that price it's made a few compromises, so you get rim brakes rather than discs, although we found them as effective as the cable operated discs that you're likely to find at this price. 

You also don't get quite the full 11-speed Shimano 105 groupset, with an FSA chainset, but it's impressive for the price. Tyre clearance at 28mm is okay, but wider rubber would up the compliance.

Read our full review of the Boardman SLR 8.9 here.

Wide tyres and IsoSpeed provide all-day comfort 

7. Trek Domane SL6

The Trek Domane has evolved over the years into an extremely capable endurance road bike that can tackle long miles on surprisingly rough terrain. Part of its magic is the inclusion of the front and rear IsoSpeed decouplers; these pivot-based flex points take the square edge off big hits without sacrificing any efficiency or power transfer.

The other piece of the pie is the tyre clearance. There is room in the frame for up to 38c tyres (35c with fenders), which also makes it somewhat gravel-friendly. Trek has also integrated nifty down tube storage that comes with a tool roll and is big enough for a few spares and tools or heaps of snacks.

We reviewed the 2019 SL 6 but the 2022 version is offered with both Shimano's Ultegra groupset (as tested) or if you prefer electronic shifting, SRAM's Rival eTap AXS. There's a broad range of Domane models in the range, starting with the sub-£1000 alloy Domane and topped off by the Domane SLR 9 at over £11,000, so it's worth reading our Trek bike range overview for more context.

The BMC Roadmachine offers fast handling along with comfort

8. BMC Roadmachine 01 Four Di2

The Roadmachine from Swiss brand BMC has the slightly more upright ride position, tubes shaped for compliance and space for tyres up to 33mm that mark it out for endurance riders. It's a bit faster handling than many endurance bikes though.

The Roadmachine 01 comes with BMC's top end carbon and an Ultegra Di2 groupset. There's a D-shaped seatpost, also designed to smooth the road and BMC's integrated cockpit for clean looks. There are no fittings for full mudguards, but BMC does make a rear clip-on that's mounted to the rear of the seatpost to help keep your rear end dry.

Countervail tech helps add comfort to the Infinito XE

9. Bianchi Infinito XE Disc

Painted up in its trademark celeste green, the Bianchi Infinito XE sees a slightly more relaxed position than its racier cousins with a taller head tube and a slightly longer wheelbase — which also makes more room between the rear stays for bigger 32c tyres.

But hidden between the layers of carbon that make up the frame is Bianchi's Countervail vibration cancelling technology. The viscoelastic material which is incorporated into the layup was originally developed for NASA and does surprisingly well to eat up harsh road vibrations before they reach the touchpoints. The layup also sees the same Carbon Nano Technology used in the Oltre XR which reduces the gaps between the resin and carbon fibres vastly increasing the overall stretch and stiffness.

All of this adds up to a planted and confident frame that creates a plush ride, but with chunky tubing that is unyielding to twisting and flexing during big efforts and sprints.

The current model is offered across three builds: 11-speed Shimano 105, Ultegra and SRAM Rival eTap AXS. 

Read our full review of the Bianchi Infinito XE .

What is an endurance or sportive bike?

An endurance bike, otherwise referred to as a sportive or gran fondo bike, is a bike that has been designed to make long days in the saddle just that little bit easier by providing a more comfortable ride that should not only protect your backside from all the vibrations passing through your seat-post and saddle, but should also keep your legs fresher after multiple hours on the road.

These bikes have become increasingly popular over the last few years for two main reasons. First, the huge growth of sportives and fondos has meant that there are more and more people whose main concern when buying a new bike is that it makes eating up the miles on long rides that bit more pleasant. And second, most people don't get to ride on velvety Swiss roads, and so as to tackle broken tamac and chip seal most riders generally value a bike that is able to take the worst out of rough tarmac.

How should an endurance bike ride?

Comfort is your primary concern when buying an endurance bike. As most of your weight is supported by your saddle rather than the handlebars, it is most important that the back-end of the bike is comfortable. However, depending on your position, your arms and wrists will still be bearing a fair amount of your weight so front end comfort is still important.

But comfort is not the be-all and end-all with an endurance bike. After all, comfort is not going to be your only concern 100-percent of the time, and you still want a bike that is able to respond and give an exciting ride when you want to put the hammer down.

This means that you don't want a bike that provides comfort by building flexibility into every part of the frame as this will result in a frame that cannot respond to quick bursts of power and will mean that you can't hold your speed as well. So any extra comfort would be offset by the extra time that you have to spend out on the road due to lower average speeds.

As you're not going to be tearing up a tight and twisty criterium circuit on an endurance bike, the handling should be leaning towards the more chilled out end of the spectrum. This means that you need to put in more effort to navigate the bike through corners, which might sound like a bad thing, but also means that less effort is required to keep it on the straight and narrow.

Don't worry though, it should still be able to cope with everything but seriously fast and technical descents. And anyway, your bike handling is probably more important than the bike's handling when it comes to cornering.

What is endurance bike geometry?

The geometry is one of the most important elements that defines how a bike rides. Indeed, give an expert a geometry chart and they will be able to have a pretty good guess at the type of bike that they are looking at and how it rides.

The geometry of an endurance bike is tuned to add comfort and stability

There are a number of features of an endurance bike's geometry that should make it comfortable for riding long distances over rough terrain, normally including a more upright riding position that will place less stress on your back and neck.

The first thing to look for is a taller head tube, which will usually be more than 17cm for a 56cm frame, although on some bikes it will be approaching 20cm, which will mean that you don't have to lean over as far to reach the bars. Of course, this position can always be tweaked by the use of spacers underneath the stem and by using stems of different angles.

Endurance bikes will also usually come with a slightly shorter top tube, which will effectively bring the saddle and handlebars closer together. Again this will mean a more upright, less stretched out position to reduce the strain on your back and neck.

Other endurance bike geometry features are designed to improve the comfort of the frame and to alter the bike's handling. Most endurance bikes have a slightly slacker head tube angle and greater fork rake, which will create a more compliant front end and more stable handling, while a longer wheelbase (occasionally greater than a metre) also makes for a less twitchy ride.

Slacker frame angles add stability

What makes an endurance bike comfortable?

Aside from the geometry there are a whole load of different features that different manufacturers build into their endurance bikes to try and make them stand out from the crowd.

One of the most popular such features is the use of some sort of suspension or vibration dampening technology to reduce the amount of road buzz that is transmitted through the frame and into your body. Two of the most well-known are Trek's IsoSpeed decoupler technology and Specialized's Future Shock, although there are other similar systems used by the likes of Pinarello and Lapierre. Other brands like Bianchi (see above) and Look build layers of vibration absorbing materials into their carbon layups.

Yet other manufacturers create comfortable endurance bikes by working with the carbon-fibre layups of the frames to build flex into areas like the seatstays and top tube while other areas of the frame are stiffened up to make sure that power transfer isn't hindered.

Features like Trek's IsoSpeed increase ride comfort

What components should I look out for on an endurance bike?

As when buying any new bike, the most important thing to look at when buying an endurance bike is the groupset. Most endurance bikes will come with gearing with a wide range that should enable you to get up some pretty steep hills even when tired at the end of a long ride but still ride relatively fast on flat and downhill runs.

This will usually mean a compact chainset (50/34t) and a wide range cassette with a 32t or even 34t largest sprocket. SRAM eTap AXS cassettes go out to 36 teeth. Along with smaller chainrings, enabled by SRAM's cassettes going down to 10 teeth, that means that there's more range on the large chainring before you need to change down and a lot of low range with the small chainring, which goes well below 1:1. 

However, your choice of groupset won't affect the comfort of your endurance bike, while your choice of wheels and tyres certainly will.

You probably won't get much of a choice if you're buying a complete bike, but some wheels with wider rims combined with wider tyres will improve the comfort of the ride. More and more endurance bikes are coming with clearance for 28mm, 30mm or even wider tyres , which can be run at lower pressures to soak up road vibrations, and come with the added benefit of better grip and lower rolling resistance. Most of them can be run tubeless too, which lets you lower tyre pressure even more.

The benefits are greater when combined with wider rims , which allow for a greater volume of air within the tyre at any given pressure, and therefore a more comfortable ride, as well as making for a wheel that is also able to absorb more vibrations from the road and greater tyre stability for predictable cornering.

Endurance bikes typically offer a wide gear range

Finally, the majority of endurance bikes come with disc brakes rather than rim brakes. These are by no means a deal breaker, but certainly offer a number of benefits over rim brakes. Most notably you get more consistent braking performance in wet and dry conditions, while they have more braking power and better modulation as you don't need to squeeze the brake lever as hard to apply the brakes. 

More expensive bikes are likely to have hydraulic rather than mechanical disc brakes. In general hydraulic systems are more powerful than mechanical disc brakes and they're a closed system so not subject to contamination and should be lower maintenance.

How must does an endurance bike cost?

There's no need to splash the cash in search of a good endurance bike. The geometry is probably the most important thing in creating a comfortable endurance bike, and in general bikes at the lower end of the market have a more relaxed geometry. This means that you should be able to pick up a comfortable endurance bike for well under a grand.

However, if you want something made out of carbon fibre and featuring the bells and whistles of some snazzy vibration dampening technology, then you can spend a lot more than that. £2,000 / $2500 and a bit of shopping around should be able to secure you a bike with the same frame design features as used by the pros in the likes of Paris-Roubaix and the Tour of Flanders, albeit made with a cheaper mix of carbon fibre and with a cheaper (although usually perfectly good) groupset and heavier wheels.

Spending more money than this will move you up the groupset ladder but might not give you a significantly better frame, so it's worth considering whether this extra money is better spent on other kit, such as some high quality shorts which will greatly improve your comfort on long days in the saddle, or a bike fit which could relieve any aches and pains that you get from riding.

Best climbing bikes 2024 | Lightweight bikes for when the road points upwards

The top lightweight road bikes for climbing

Russell Burton / Our Media

Simon von Bromley

The best climbing bikes are low-weight, helping you conquer the longest (or steepest) ascents.

There's a definite buzz to riding a fast, flyweight machine, and many road cyclists love the fast acceleration and responsiveness of climbing bikes.

A modern lightweight bike has to prove itself not solely through whether it's under the UCI weight limit, but also by having the aerodynamics to up your ride speed on descents and the flat.

Keep reading to see our pick of the best climbing bikes and to find out more about these lightweight bikes, check out our buyer's guide at the end of this article .

Best climbing bikes 2024, as rated by our expert testers

Giant tcr advanced sl 0 disc.

• £9,699 / $11,000 / AU$13,499 as tested
• Weight: 6.7kg (L)
• Pros: Light, stiff and responsive race bike; top-spec build
• Cons: Exposed brake hoses; narrow tyres

The Giant TCR has long been a benchmark for race bikes and the ninth generation of the bike remains a top performer.

While the TCR comes in many variants to suit different budgets, the Advanced SL 0 model is unapologetically high-end and its frameset sports an integrated seatpost with a topper rather than a conventional one.

With a full SRAM Red eTap AXS wireless groupset and carbon wheels from Giant's in-house brand Cadex, it's ready to race out of the box and is properly light.

Bianchi Specialissima

• £11,206 / $11,626 / €11,449 as tested
• Weight: 7.2kg (59cm)
• Pros: Great mix of speed, handling, control and smoothness
• Cons: Wheels are a bit of a disappointment

The Bianchi Specialissima is a bike that's gone from round tubes to aero profiles in its latest iteration, also gaining disc brakes and hiding the hoses, while still ticking the lightweight boxes with a 750g frame and 370g fork. You could lose another 80g by opting for black paint instead of celeste.

Bianchi incorporates Countervail anti-vibration tech into the frame and the bike comes with Shimano Dura-Ace 12-speed shifting and other top-notch kit. The Vision SC 40 carbon tubeless wheels feel a little low-value compared to the rest of the spec though (even at £11,000).

The ride is a mix of responsiveness with great handling, while also composed, smooth and more comfortable than some bikes with tyres wider than the Specialissima's 26mm Pirellis.

Cannondale SuperSix Evo Hi-Mod 2

• £8,250 / $8,300 / €8,999 / AU$11,999 as tested
• Weight: 7.57kg (56cm)
• Pros: Excellent handling combined with compliance and stiffness
• Cons: Vision Trimax handlebar may not suit those with smaller hands

Now in its fourth generation, the SuperSix Evo continues to cement itself as one of the best climbing bikes. The new bike takes much of what made the previous versions so well regarded, but removes the often-maligned PF30a press-fit bottom bracket and replaces it with a 68mm BSA threaded model. The front-end design and down tube have also been refined and there's a new proprietary seatpost, too.

Out on the road, the SuperSix Evo balances its inspired handling with compliance and stiffness. It's a particularly adept climber, feeling assured and firm when under the rider and when you want to put the power down, it rockets forward. The new aero seatpost isn't as stiff as you might expect, offering a good amount of buzz-reducing compliance.

The Shimano Ultegra R8100 groupset on this build is BikeRadar's pick of the Japanese brand's latest groupsets and we were impressed by the newly updated flagship HollowGram R-SL 50 wheels, too. Although Cannondale specs Continental Grand Prix 5000 tyres, they're in a 25mm width and we'd be keen to run wider rubber. We also suspect the Vision Trimax won't suit those with smaller hands because the tops are very deep.

Canyon Ultimate CF SLX 8 Di2

• £6,199 / $5,499 / €6,499 / AU$9,899 as tested
• Weight: 7.26kg (L)
• Pros: Cheaper than Ultimate CFR; smother than Ultimate CFR
• Cons: Can’t customise components at purchase

The Canyon Ultimate CF SLX 8 Di2 sits below the range-topping CFR, but our tester found it to be smoother with the same handling and stiffness as the pricier model.

In short, you get better value for money with this Shimano Ultegra-equipped bike and a more balanced ride, earning it a place on the very top shelf of current road bikes.

It’s a shame you can’t customise the build at the point of purchase, which might be an annoyance if you prefer an inline seatpost.

ENVE Melee (Ultegra Di2 build)

• £5,500 / $5,500 / €5,500 for frame 'chassis' | £10,400 / $12,834 / AU$19,220 as tested
• Weight: 7.8kg (58cm in this example build)
• Pros: Outstanding handling balanced with great comfort and geometry
• Cons: Expensive and you can't buy a full build off the peg

The ENVE Melee took our 2024 Performance Bike of the Year crown, thanks to its outstanding handling and balanced comfort. The brand's second bike after the Custom Road has been aerodynamically optimised, albeit with a slightly taller ride position than you'll find on longer and lower bikes. The Melee also fully integrates its cables and hoses and uses a D-shaped seatpost.

We found the Melee to be one of the easiest-handling race bikes on the market and we were struck by how stable and composed it is in every scenario. It deals with everything with real calmness.

A stable and composed ride can sometimes be a little boring, but there's none of that here. The Melee's reaction to inputs is quick and it's unperturbed by crosswinds.

Unlike the other bikes on this list, the Melee is sold as a 'chassis' – a frame, fork, stem, handlebar, seatpost and thru-axles. You then build the bike up with your preferred electronic groupset , wheels and tyres. Even in a modest build, that means the Melee is far from a cheap proposition, but the ability to mould it into your own makes it a real winner.

Our example build came with a Shimano Ultegra R8100 groupset, and ENVE's Foundation 45 carbon wheels and SES tyres in a 29mm width.

Focus Izalco Max 9.7 AXS

• £5,699 / €6,199 / AU$8,999 as tested
• Weight: 7.9kg (L)
• Pros: Racy handling; decent value
• Cons: Grey paint scheme

Similar to many other bikes in this category, Focus has evolved its Izalco platform to be more well-rounded.

The latest version takes both weight and aerodynamics into account, but doesn’t go so far as to ignore practicality completely – the aero cockpit, for example, uses a standard stem and handlebar setup to make fit adjustment and maintenance a little easier.

At 7.9kg (size large), it’s not the lightest bike we’ve ever tested, but this does include 50mm-deep aero wheels and, with a frame weight of just 890g (claimed), it could certainly be lightened up considerably with a few weight-weenie optimisations.

There’s also a slightly cheaper version, the Izalco Max Disc 8.8 , that has Ultegra R8000 mechanical gears, but performed similarly well in our testing.

• Read our full Focus Izalco Max 9.7 AXS review

Lapierre Xelius SL 9.0

• £7,399 / €7,799 as tested
• Weight: 7.5kg (L)
• Pros: Good-value spec; racy geometry
• Cons: Limited sizing; can be twitchy in the wind

Another lightweight bike with aero features, the Xelius nevertheless stands out thanks to the design of its seatstays. The navy blue fade glitter paintjob looks stunning and the racy geometry leads to sharp handling.

If you're at either extreme of the size range, the five sizes available may not work for you though.

The spec is really good for the price, with 12-speed Dura-Ace Di2, a carbon bar and stem and Lapierre's own-brand carbon wheels with 25mm Continental GP5000 tyres that measure 27mm on the 47mm-deep, 21mm internal-width rims.

• Read our full Lapierre Xelius SL 9.0 review

Merida Scultura Team

• £8,000 / €9,999 as tested
• Weight: 7.1kg (M)
• Pros: Great value for a pro-level spec; exciting ride
• Cons: Tricky fit adjustment

The Merida Scultura Team took our 2022 Performance Bike of the Year crown, thanks to its superb, exciting ride and racy handling. It's also great value, with a Shimano Dura-Ace 12-speed groupset, complete with power meter.

Merida has shaved 4.2 per cent from the previous Scultura's drag numbers, while also lowering weight slightly to a claimed 822g for a size M frame. It's well kitted out; we particularly liked the Vision Metron 45 SL wheels, their 1,372g weight leading to low inertia on climbs. They're shod with 28mm Continental GP5000 tyres for a comfortable ride.

The one downside is the lack of narrower options for the integrated bar/stem.

Specialized S-Works Tarmac SL8 Dura-Ace Di2

• £12,000 / $14,000 / €14,000 / AU$19,900 as tested
• Weight: 6.76kg (56cm)
• Pros: Exceptionally well-balanced handling; aero bike speed
• Cons: Wider tyres would be beneficial; cost

The Specialized S-Works Tarmac SL8 is the brand’s latest flagship road bike.

The SL8 rides like a dream with exceptionally well-balanced handling. It has the speed of an aero bike and it’s a fantastic climber.

Our tester described this no-expense-spared build, featuring Shimano Dura-Ace, as one of the finest race bikes available. But he cautioned that it doesn’t shift the goalposts far enough from the performance of the previous-generation SL7 to warrant upgrading.

• Read our full Specialized S-Works Tarmac SL8 review

Basso Diamante Ultegra Di2

• £7,199 / €8,299 as tested
• Weight: 7.58kg (58cm)
• Pros: Sharp but stable race geometry
• Cons: Long and low cockpit won't work for everyone

The eighth-generation Diamante is a thoroughbred race bike, while remaining classic in its appearance. The tube shapes are rounded, which Basso says is designed to improve stiffness and efficiency, while minimising weight.

The geometry is in pure race bike territory – long and low, so you'll want to have a long think about whether it will work for you and carefully study the geometry chart. That said, in testing we found the Diamante to balance its tactile handling with satisfying stiffness. It's surprisingly comfortable, too, thanks to the slim seatstays and carbon seatpost.

There's little to criticise with the Ultegra Di2 specced. The second-tier groupset delivers identical shifting and braking performance to Dura-Ace with a compelling cost saving. We also rated the Microtech RE38 wheels – many own-brand efforts can vary in design modernity, but these are on the money with a 23mm internal rim width.

• Read our full Basso Diamante Ultegra Di2 review

BMC Teammachine SLR 01 Two

• £9,800 / $10,999 / €10,499 as tested
• Weight: 7.09kg (56cm)
• Pros: Lightweight and fast
• Cons: High price

The latest iteration of BMC’s excellent Teammachine learns lessons from the Timemachine (BMC’s aero road bike) to improve its aerodynamic efficiency, without adding too much weight.

In fact, its 7.09kg weight makes the BMC Teammachine SLR 01 Two one of the lightest bikes on this list, and that’s seriously impressive considering it has aero wheels, disc brakes and plenty of other aero features.

The omission of a Dura-Ace crankset in favour of Rotor is perhaps the only minor criticism we could make of a bike that's otherwise extremely hard to find fault with. There’s no denying it comes at a very high price though.

• Read our full BMC Teammachine SLR 01 Two review

Canyon Ultimate CFR Di2

• £10,399 as tested
• Weight: 6.3kg (L)
• Pros: More versatile than ever
• Cons: Inconsistent spec

The Canyon Ultimate CFR Di2 is tremendously expensive and light at a mere 6.3kg in size large.

The top-dog Ultimate retains its race-winning stiffness, agility and climbing ability while becoming ever more aerodynamic.

However, the shallow-section DT Swiss wheels undermine the Ultimate's versatility, while the Schwalbe Pro One TT tyres are a puncture risk on all but the smoothest roads.

• Read our full Canyon Ultimate CFR Di2 review

Cervélo R5 Disc Force eTap AXS

• £8,599 / €8,799 / $8,400 as tested
• Weight: 7.4kg (56cm)
• Pros: Stiff, but not too stiff frameset; includes power meter
• Cons: Expensive compared to competition

Cervélo claims a 703g frame weight for the latest R5 and, like all Cervélos, there's an aero edge, with Squoval tube profiles and smooth frame edges, while internal hose routing saves a claimed 3W at 48km/h.

The SRAM Force AXS chainset comes with a power meter and the bike is equipped with Reserve 34/37mm carbon wheels, although they're planned to be swapped out for Zipp ZR1 wheels from 2024. The 25mm Vittoria Corsa tyres measure around 29mm on the wide rims.

Cervélo has a reputation for stiff frames, but the latest R5 is slightly less stiff than its predecessor. The geometry is racy, leading to an agile, predictable ride, and the light weight and good power transfer make for sprightly climbing.

Colnago C68

• £11,753 / $15,772 / €14,065 as tested
• Weight: 7.3kg (58cm equivalent)
• Pros: Beautifully built; superb handling
• Cons: Saddle should be better at this price

Colnago uses its lugged construction on the C68, but the tube shapes are more reminiscent of the monocoque V3R . Colnago fits its own comfortable one-piece cockpit with hidden cable routing.

The ride position is long and low, although not too aggressive for less flexible riders and leads to great handling from the taut frame.

There's a full Dura-Ace R9200 build, including C50 wheels with 28mm Pirelli tyres, although the Prologo saddle isn't the range-topping carbon-railed version. It's a great bike that merits its superbike rating.

• Read our full Colnago C68 review

Colnago V4RS

• £5,000 / €12,630 as tested (UK price is for frameset only)
• Weight: 7.23kg (57cm)
• Pros: Pinpoint handling
• Cons: Seriously expensive

Ridden by UAE Team Emirates (and perhaps most importantly) Tadej Pogačar, the V4RS is Colnago's monocoque carbon race bike, where a balance of lightness, stiffness and speed is the name of the game.

Colnago claims the V4RS is 3 per cent more aerodynamic than the outgoing V3RS and the new CC01 cockpit alone is said to be 16 per cent more aerodynamic. There are some new tube shapes too, with a reprofiled head tube, although many will be glad to hear the brand has reverted back to a round steerer tube.

Out on the road, the V4RS is unerringly poised, with direct handling and sharpness. It felt particularly confident on descents, driving hard into an apex and the bottom bracket laps up power when climbing, the bike keen to accelerate when you get out of the saddle.

Giant TCR Advanced Pro 2 Disc

• £2,999 / $5,199 / €3,100 as tested
• Weight: 7.87kg (M/L)
• Pros: Solid all-round spec; lively ride quality; generous tyre clearance
• Cons: Limits aftermarket upgrades

The legendary TCR has finally gone aero, but that doesn’t mean a huge increase in weight, fortunately.

At 7.87kg, it’s not the lightest bike on this list, but it’s very competitive in its price range and could likely be lightened considerably with some component upgrades.

It also offers a noticeably smooth ride, with confident handling and clearance for up to 32mm tyres, which is very welcome.

Giant’s sister company Liv offers a women's version called the Langma Advanced Pro Disc, which is one of the best women's road bikes .

Scott Addict RC 10

• £5,949 / $8,000 / €6,599 as tested
• Weight: 7.9kg (56cm)
• Pros: Quality ride; power meter
• Cons: Middling wheels and mediocre tyres

The Scott Addict marries sharp handling with a predictable and compliant ride quality that's similar to the Cervélo R5. There's integrated cabling that works for mechanical and wired electronic, as well as wireless shifting, and it's reasonably easy to work on.

Scott includes a power meter with the SRAM Force AXS electronic groupset and you get decent, if not outstanding, Syncros Capital 1.0 35 Disc wheels with a claimed weight of 1,574g a pair.

We were disappointed with the fitted Schwalbe One TLE tyres though, with their higher rolling resistance than many of the best road bike tyres . Tyre clearance is a little narrow at 28mm too.

Although this mid-spec Addict weighs just under 8kg, you can spend a lot more and get the bike's claimed weight down to 6.7kg.

• Read our full Scott Addict RC 10 review

Specialized Aethos Comp

• £4,500 / $5,000 / €5,400 / AU$6,900 as tested
• Weight: 8.2kg (58cm)
• Pros: Rapid handling, but stable ride quality; climbs well
• Cons: Wheelset and tyres limit performance

Although the Comp spec of the Specialized Aethos weighs over 8kg, the top-spec S-Works Aethos brings that down to a claimed sub-6kg, definitely earning a place on our lightweight bikes list. The classic frame profile with round tubes goes against the aero-is-everything modern trend.

The Comp uses a lower-spec carbon than the S-Works, but still has a 700g frame weight and comes with a SRAM Rival AXS groupset and lower-priced, heavier wheels. These make it feel less skittish than the S-Works bike, while it retains its rapid handling and shares its geometry with the Tarmac SL7. It still feels light when climbing too.

• Read our full Specialized Aethos Comp review

Specialized S-Works Tarmac SL7

• £10,500 / $12,000 / €11,499 / AU$18,000 as tested
• Weight: 6.7kg (54cm)
• Pros: Stiff, fast and responsive
• Cons: Ride might be too racy for some; that price tag

The Specialized Tarmac SL7 has now been replaced by the Tarmac SL8, but you can still find this bike for sale.

The Tarmac SL7 is disc-only and has clearance for 32mm tyres. It's a fast and uncompromising race bike that will delight riders who can kick out big power numbers.

In its halo S-Works spec, this is a seriously expensive bike, but more affordable models are available, with the second-tier frame claimed to weigh a respectable 920g.

• Read our full Specialized S-Works Tarmac SL7 review

Trek Emonda SL 6 Pro

• £3,350 / $3,799 / €3,799 / AU$5,499 as tested
• Weight: 8.13kg (56cm)
• Pros: Stiff, exciting ride; great-quality components
• Cons: 25mm tyres harm performance; uncompetitive weight

In line with market trends, Trek has amended the Emonda’s design parameters to encompass a broader, all-round riding style, with the obligatory disc brakes and aero optimisation.

This does mean builds won’t quite be able to match the positively feathery lows of previous models , but Trek is, unsurprisingly, adamant they are faster most of the time. Our tester broadly agrees with this sentiment too, heaping praise on the Emonda's speed and stiffness.

It’s also worth considering Trek’s beautiful Emonda ALR . Not only are there rim and disc brake versions of that frame (as things stand), but it’s also substantially cheaper. We think it’s an absolute peach of a bike.

Trek says the Emonda is now a unisex bike, and offers a broad range of sizes (from 47cm to 65cm) with the intention of fitting all different kinds of cyclists.

What we've included (and what we haven't)

This buyer's guide features lightweight bikes at a range of prices, reviewed by BikeRadar and having scored at least four stars in our testing.

While lighter bikes may be available (including custom builds and different models within a given manufacturer's range), these are bikes we have tried and tested, and can confidently vouch for as a result.

Buyer’s guide to climbing bikes

It perhaps goes without saying, but when you’re riding uphill, gravity is always trying to pull you back down.

Reducing the total rider plus bike system weight means less energy (or power , in cycling parlance) is required to maintain a given speed while climbing.

Therefore, if you want to ride uphill faster, or simply make the hills a little easier, a lightweight bike helps a lot.

It’s for this reason we see hill-climb obsessives chopping and changing practically every component to bring their overall bike weight down to its lowest possible limit.

The only issues are that high-end, lightweight bikes and parts can be eye-wateringly expensive, and the weight-weenie bug can be hard to shake once you get started. However, some of the best road bikes under £3,000 are good for climbing.

Cheaper still is improving your power-to-weight ratio . You can do this by becoming more powerful at the same weight or losing weight through cycling and maintaining power.

Top-quality carbon fibre is prized for its incredible stiffness-to-weight ratio, and rightly so – this is the reason it’s used in Formula One. If you can afford it, the lightest bikes and parts will almost always be made out of high-end carbon fibre.

At the lower end though, good aluminium is competitive with, or even better than, cheap carbon fibre. That applies not just to weight and stiffness, but also ride quality and strength.

The very last of those characteristics is also a general worry for ultra-lightweight carbon fibre frames and parts. You have to be very careful about sticking to recommended weight, torque and clamping specs, or else it’s very easy to break these feathery items.

Aero vs. weight for climbing

Until fairly recently, climbing bikes made no concessions to aerodynamics, leaving drag-reduction to the best aero road bikes . But with the rise of computer modelling, on-bike aero sensors and other advanced testing techniques, this has all changed.

Even dedicated climbing bikes are now launching, with brands touting their aerodynamic efficiency.

Take the Trek Emonda , for example. Trek says it has been designed specifically for the rigours of iconic Tour de France climbs such as Alpe d’Huez (a 13.85km monster in the French Alps), yet still features extensive aero treatment.

True hill climb aficionados will no doubt be tearing their hair out at this point, exclaiming ‘anything under 10 per cent isn’t even a proper hill anyway!’, but if you want to go fast, aero always matters, regardless of the gradient.

It's true that aerodynamic drag becomes a smaller part of the equation as gradients increase in severity, but the absolute amount of air resistance you experience remains the same for any given speed.

On top of that, the power to overcome any increase in air resistance is proportional to the cube of speed. So, if you want to ride your bicycle twice as fast, you’ll need eight times more power to overcome the extra drag force, unless you can reduce your aerodynamic drag.

In an ideal world, then, you want a bike that’s both lightweight and aero for smashing hills.

"Weight weenies should be Crr weenies"

So said Robert Chung, Professor and Theoretical Mathematical Demographer at the University of California-Berkeley. Chung is perhaps most famous for devising the ‘Chung Method’ of calculating aerodynamic drag, but he also reminds us of the importance of not ignoring rolling resistance.

Using a power equation for wheeled vehicles (such as the one found at www.kreuzotter.de ), he showed that even a relatively small difference in rolling resistance (Crr stands for 'coefficient of rolling resistance') can be worth as much as large changes in weight, even on steep gradients.

Chung's graph plots the difference in Crr between Continental’s GP4000S II and GP5000 tyres in terms of the equivalent efficiency found through weight loss on different gradients.

On a flat road, it’s clear that even a relatively small decrease in rolling resistance is worth more than practically any increase in weight. What’s really interesting to note though, is that changing from a GP4000 to a GP5000 is still worth more than 500g of extra mass even on a 10 per cent slope.

Yes, that’s right; the small difference in rolling resistance between two of the best road bikes tyres can have a greater effect on your efficiency than 500g of extra weight even on a 10 per cent slope, and that equivalent mass penalty only increases as the gradient gets shallower. On a 6 per cent slope, the difference is equivalent to a kilogram of extra mass.

The key takeaway is that you shouldn’t just look at weight figures when shopping for tyres. The differences in rolling resistance between tyres will be worth far more to your climbing speed than any minor weight variations.

Gearing and cadence when climbing

Some riders apparently enjoy using singlespeed or even fixed-gear bikes for climbing hills . But most people are going to want bike gears .

For a long time though, back in the days when riders only had five or so cogs on their cassette to choose from, gears such as 42×21 were considered adequate for climbing mountains.

Thankfully, though, things have moved on and we now have access to compact/sub-compact chainsets , long-cage rear derailleurs and much larger bike cassettes .

Used together, these can allow practically anyone to spin up steep climbs at a comfortable cycling cadence , rather than turning them into a series of leg presses.

Muscling up a steep hill in a massive gear might feel heroic, but it’s probably slower and it’s costing you more energy too, as anyone with a power meter will be able to attest to. These days, even the pros know you need to gear down when the road goes up .

Rim or disc brakes

Another thorny issue. In our opinion, there are two answers to the bike brakes debates – a simple one and a nuanced one.

The simple answer is that rim brakes are, generally, lighter, and therefore are better for climbing bikes .

There's a more nuanced answer, however. While disc-brake equipped bikes generally come with a weight penalty (though this is becoming harder to measure because, despite what we wrote in 2017 , new high-end rim brake road bikes are uncommon), the advantage of better braking will be keenly felt on the way down the hills.

If the only thing you care about is going uphill as fast as possible, then rim brakes could still be the right choice. Otherwise, the advantages of road disc brakes might tip the balance.

Scott Bikes Vs Trek Bikes Compared ?

Scott and Trek are two close brands known for their high-end brands and impressive sponsorship deals. But given that Giant makes frames for both brands, how do Scott bikes vs Trek bikes compare?

While Scott only offers a 5-year frame warranty, Trek offers limited lifetime coverage, which shows Trek’s confidence in the quality of their bike frames. Scott bikes, however, are less costly but promising the same high-end components as Trek.

Of course, there are a few other minor differences between the two brands that I’ll talk about.

Not only will I compare the two bike brands in detail, but I’ll also compare their various bike types. In particular, I’ll look at their road bikes, MTBs, and hybrids to help you decide on the two.

But as I’ll discuss, it’s hard to split the two based on component quality, bike customization, bike range, and prices.

Let’s get into the comparison.

Scott Bikes Vs Trek Bikes: Side By Side Comparison

As I mentioned, Giant makes frames for both Scott and Trek , which means there is little to separate the two in terms of quality.

But if you observe keenly, there are a few things that set them apart, as follows.

1. Bike Line

These two bike brands are traditional high-end, pro-level bike brands. That, however, doesn’t mean that they don’t make entry-level and mid-range options.

Overall, Trek has more entry-level bikes that beginners can ride. Scott , on the other hand, stocks mid-range options alongside their high-end bikes.

Verdict – While Trek leans towards entry-level and high-end bikes, Scott favors mid-range and high-end bikes.

2. Bike Weight

Scott bikes are slightly more lightweight than Trek bikes. Essentially, that’s owing to Scott’s impressive carbon technology.

Most of their bikes feature carbon frames that have a hollow design that makes them exceptionally lightweight.

While Trek also employs carbon technology on most bikes, they don’t feel as lightweight as Scott’s.

Verdict – Scott bikes are lighter than Trek bikes, and therefore Scott wins here.

3. Trek Vs Scott Bikes Components

Scott has an in-house brand ‘Syncros’ which is dedicated to making most of its components. That includes the saddles, wheelsets, seat posts, headsets, handlebars, grips, and kickstands .

Syncros enjoys 30 years of experience, thus reliable. The components they make for Scott are high-quality.

Trek also has an in-house manufacturer, Bontrager , which does the same job as Syncros . Like Syncros , Bontrager prides itself in making innovative and high-quality bike components.

And when it comes to the drivetrain, both brands get the components from Shimano and SRAM.

Moreover, they also source suspensions from RockShox, which are more robust and reliable.

Verdict – Though their in-house manufacturers differ, both promise quality components.

4. Bike Warranty

A good bike warranty inspires confidence. It shows you that you are getting a good deal, and this is one area where the two brands differ.

Scott only offers a 5-year limited lifetime warranty and only two years for their self-build Syncros components. Trek, in contrast, offers you a limited lifetime warranty for their frames and 1-5 years for their self-build Bontrager components.

Verdict – A lifetime warranty is a strong indicator of Trek’s confidence in their frames. For that reason, Trek wins the frame battle.

5. Purchase Route

This is another area where Scott and Trek differ. Though the purchase route has nothing to do with the bike quality, it can influence your purchasing decision.

Trek generally allows you to buy directly from their website or through their trusted local dealers.

Scott, on the other hand, relies on local dealers. You cannot order a Scott bike from their official website.

Verdict – Trek offers you more purchase routes than Scott.

6. Scott Bikes Vs Trek Bike Customization

Scott offers high-quality carbon and alloy frames for road bikes and MTBs that you can use to customize your bike.

The advantage is that the frames come as a set (frame + fork) to enjoy shock absorption.

Trek also has a bike-building project known as Project One that allows riders to design their dream Trek bike. But unlike Scott, everything is built to order with Trek, and that includes the frameset.

Verdict – Both bike brands offer you the opportunity to build your bike. Trek, however, has a slim advantage as it allows you to pick everything (including the frameset) from scratch.

7. Bike Prices

Though both bike brands offer quality components, Scott bikes’ prices are slightly lower. It doesn’t mean they are cheap, but you’ll save a few dollars getting a Scott bike over a Trek option.

Verdict – Scott wins here for offering less expensive high-end bikes than Trek. Even in terms of components, Syncros components are less costly than Trek’s Bontrager .

8. Sponsorship Success

Generally, sponsorship success is an indicator of a bike brand’s good reputation and quality bikes. That’s because pro riders only want to be associated with the best bike brands.

Scott has been sponsoring top-level cyclists for many years, and some have even won podium places at the Tour de France.

One notable athlete is Greg Lemond, the 1989 Tour de France winner. There is also Nino Schurter, the 2016 Olympics winner.

Trek also shares the same success story. Since sponsoring Lance Armstrong, the brand has been associated with so many pro riders.

Verdict – Both bike brands enjoy successful sponsorship stories, which shows their dominance in the pro riding sector.

9. Scott Vs Trek Bikes Range

Scott generally stocks the following major bike categories:

• Mountain bikes
• Gravel bikes
• Hybrid bikes
• Syncros bikes
• Electric bikes
• Women bikes
• Touring bikes

Trek, in contrast, stocks the following options:

Verdict – It seems that the two bike brands offer the same bike types. So, there is nothing to separate them here.

Scott Bikes Vs Trek Bikes Compared

After looking at the general differences and similarities between Scott and Trek, let’s look at how their road bikes, MTBs, and hybrids compare.

1. Trek Mountain Bikes Vs Scott Mountain Bikes

Here’s how Trek and Scott MTBs compare:

a) MTB Type

Scott stocks cross-country, enduro, trail, downhill, and sport MTBs as its main mountain bike ranges. Scott, however, has a dedicated women’s line and electric options.

Trek also stocks cross country, trail, and full-suspension MTBs (mostly enduro and downhill options). Like Scott, they also have a dedicated women’s bike line.

b) MTB Price

Trek mountain bike prices start as low as $600 as it’s the case with their entry-level Marlin 5 to about $11,000 as it’s the case with their high-end Super Caliber 9.1 XX1.

Scott MTBs start from around $450 as it’s the case of the Scott Active 60 Contessa to about $14,000 as it’s the case of the Scott Spark RC.

While the costliest Scott MTB is pricier than the costliest Trek, the difference is that there are more affordable Scott MTBs.

c) Suspension

Trek is known for its innovative suspension technology, which sets the bike apart from the rest.

They employ Fox and RockShox suspensions on their full-suspension MTBs, which promise unmatched control and bump absorption. So, Trek wins the full-suspension battled based on that.

But if there is an area that Scott takes the lead, it is the Hardtail line. Scott Hardtail forks come with adequate travel to offer enough cushioning.

d) Bike Geometry

Scott MTBs have a more aggressive geometry than Trek. As a result, Scott MTBs are more trail-oriented, while Trek MTBs are best for enduro cycling.

e) Carbon Technology

Both Scott and Trek employ high-quality frames, mainly carbon, on their frames. In general, carbon offers the frames a lighter weight, which makes it easy to pedal upward.

A lighter frame also makes it easy to speed up, which explains why these two bikes are popular for pro riders.

f) Drivetrain

Both bike brands employ SRAM on their high-end bikes and Shimano on their low-end and mid-range options.

2. Trek Road Bikes Vs Scott Road Bikes

Let’s compare the two road bike brands under the following:

a) Road Bike Type

Scott stocks lightweight, gravel, endurance, and aero road bikes as their main rod bike categories. They, however, have dedicated women and children lines.

Trek also makes lightweight, gravel, endurance, women, and electric road bikes. In addition, they stock performance road bikes

b) Road Bike Price

Trek road bike prices start from around $1,000, which is the case of their entry-level Domane AL2, to about $12,500, which is the case of their high-end Domane+LT9.

Scott road bikes start from around $700 as it’s the case with their entry-level Scott Speedster 50 to about $12,000 as it’s the case with Scott Addict RC Ultimate.

c) Bike Range

Scott offers a mixture of entry-level, mid-range, and high-end road bikes to suit road cyclists at different experience levels. They, however, pay more attention to mid-range and high-end markets.

Trek also makes road bikes for entry-level, mid-level, and high-end markets. They, however, focus more on the high-end and low-end market.

d) Frame Geometry

Like their MTB siblings, Scott road bikes have a more aggressive geometry, favoring pro riders more. Trek road bikes, in contrast, are less aggressive, which allows them to suit even beginners and casual road cyclists.

3. Trek Hybrid Bikes Vs Scott Hybrid Bikes

Now, let’s compare the hybrid bikes of both brands:

a) Bike Type

Scott hybrid bikes borrow so much from their road bike and MTB lines. These bikes, which are best for commuting, casual off-road rides, and weekend adventures, come in men and women options.

Trek also has fantastic hybrid bikes for men and women. But unlike Scott, Trek also offers kids hybrid bikes. And overall, both brands stock electric hybrids,

b) Carbon Technology

Impressively, both Trek and Scott employ carbon frames on their most expensive hybrid bikes, making them suitable for serious commuters. The frames make the bikes comfortable to cycle as they feel lighter.

c) Riding Comfort

There is nothing to separate the two bike brands here as they come with more upright geometries and feature wider cushioned seats.

Their most expensive options come with powerful shock suspensions and disc brakes for a more comfortable ride.

d) Bike Price

Depending on budget, you can get a Trek or Scott hybrid bike at any price point. The contrast is that Trek occupies the lowest and the highest ends of the budget.

For example, while a budget Trek hybrid costs under $500, high-end options cost over $6,000, as is the case with the Alient +9.9S.

1. Is Trek Better Than Scott?

Overall, Trek offers a better frame warranty than Scott, but Scott offers less costly bikes than Trek for the same high-end experience. So, choosing between them depends primarily on budget and warranty preference.

2. Are Scott Bikes Good Quality?

Scott employs advanced carbon technology to guarantee lighter and comfortable bikes. They also rely on self-built Syncros components such as wheels, handlebars, kickstands, and seat posts, which promise durability.

Moreover, they get their drivetrain mostly from SRAM. So, yes, Trek bikes are of good quality.

3. Does Giant Make Scott Bikes?

Giant makes bike frames not only for Scott but also for Colnago and Trek. But when it comes to components like wheelsets, handlebars, seats, seat posts, and pedals, Scott has a standalone entity within their frame, Syncros, which handles the manufacturing.

4. Are Trek Bikes Made In China?

The majority of Trek bikes are made in China, Taiwan, Netherlands, and Germany.

5. How Much Does A Scott Bike Cost?

An entry-level Scott road bike or mountain bike costs $450-$600, while a high-end option costs up to $12,000.

Scott Bikes Vs Trek Bikes: Closing Thought:

You now know what to go for between Scott and Trek. If you are on a budget and want a decent bike, consider Trek. But if you want a lighter bike with high-end components, then Scott is a realistic option.

But overall, it’s good to look at the specs carefully as not all Scott bikes are better than Trek bikes. Similarly, it’s good to consider the budget as not all Scott bikes are cheaper than Trek bikes.

If you’re looking for a comparison of the Trek Émonda SL5 and the SL6, then you’ve come to the right place.

I’ve been researching these two awesome machines from Trek and have pulled together a number of resources which I hope will make choosing between them a little easier. First up, we have the full specification list for each bike – a head-to-head comparison so that you can easily cross-reference every component on the SL5 with its peer on the SL6. Next, I’ll highlight the major pros and cons of them and, finally, I’ve written up an in-depth review of the Émonda range, with a deep-dive on the SL5 and SL6.

If you think the choice comes down to a straight shoot-out between Shimano’s 105 and Ultegra systems, you wouldn’t be totally wrong. But that misses a number of critical differences which will undoubtedly have a bearing on your decision.

My conclusion though is that (1) I’d choose the Émonda SL6 over the SL5 and also that (2) both the bikes are fantastic, and you’ll be riding with a grin plastered on your face whichever one you go for.

Let’s take a look at the details, kicking off with the spec list rundown.

Trek Émonda range overview

Launched in 2014, the Émonda was (and still is) the top-flight mountain climber in Trek’s road bike arsenal, thanks to their obsession with weight reduction and the super-stiff and responsive frame. But the new Émonda is no “one-trick pony” and will excel whatever the terrain. The move to H1.5 geometry and aero style tubing, combined with the internally-routed cabling, make this a fast bike whether you’re going up, down or flat out on the flats.

There are 7 models in the current Émonda line-up, plus a frame-only option if you’d prefer to build your own. The SL5 is the entry-level model in the range – though this is said with a grin and a glint in the eye as there’s not much that’s “entry-level” about this work of art. Top of the tree is the SL7 Disc eTap – carbon throughout (including the wheels) and with a full wireless electronic drivetrain. It’s expensive (over double what you’d pay for the SL5) but, if you’ve got the budget available, then you won’t regret spending it on the SL7 eTap. Although the rest of your riding buddies might.

Let’s take a more detailed look at the SL5 and SL6. We’ll see how they compare against each other. Highlight the pros and cons of each bike. See which has the best spec for the money and finally come to a conclusion about which is the bike to go for.

Trek Émonda SL5 Disc Review

Pros Race-ready Carbon frame and forks Full Shimano 105 drivetrain Shimano 105 hydraulic disc brakes Very light (20.18 lbs) More wallet-friendly than the SL6

Cons No Ultegra components like the SL6 has Heavier wire bead tires than the SL6’s aramid bead 2 lbs heavier than the SL6

There can’t be many “entry level” road bikes that are as droolworthy as the SL5 Disc. If you like to ride fast then the Émonda SL5 is an excellent starting point and, if you’ve got racing in mind, then this could be the bike that sees you to the podium.

Both the SL5 and SL6 have identical carbon frames, with the new aero styling that Trek has bestowed on the Émonda range. This, combined with the carbon forks, give a bike that is light, stiff and highly responsive. Trek says that the aero tube shapes, along with the internal cable routing, will play a measurable role when you’re traveling at speed. This was essentially ‘free speed’ that was just being left on the start line beforehand, so it’s fantastic to see these changes by the team at Trek.

Looking at the buyer reviews, we see a lot of happy and smiling faces. That’s testament to how enjoyable a bike SL5 is to ride. Lots of comments describe the speed and agility of this bike. I’ll mention the negative comments, but there are only a few. There’s concern over the stock saddle and stock wheels – both of which are easy to upgrade – and also the apparent ‘middle of the road components’.

Let’s take a look at those ‘middle of the road components’ because they’re the 800-pound bike tech in the corner of the bike shop. Shimano 105 vs Shimano Ultegra drivetrain – what’s the deal?

Look around on the bike forums and you’ll see plenty of opinions on these two systems. Well, here’s my take on them. First up, both are excellent. They perform great, when and where you need them to. That goes for both the drivetrain and the brakes. If you’re a mid-level club cyclist you’re unlikely to notice a difference in the performance between the two.

Where you will notice a difference between the 105 and the Ultegra is in the weight and the cost. The SL5 is around 2 lbs heavier and $800 cheaper than the SL6 and much of that is due to the upgrade from 105 to Ultegra.

Which brings us to the SL6.

Trek Émonda SL6 Disc Review

Pros Race-ready Carbon frame and forks Full Shimano Ultegra drivetrain Shimano Ultegra hydraulic disc brakes Super light (18.18 lbs!) – that’s only a few ounces less than the SL7 eTap

Cons Around $800 more expensive than the SL5

I’ll start by saying that, of the two bikes, this is the one that I would choose every time.

Yes, it’s substantially more expensive than the SL5 Disc. No, I can’t feel a significant difference in performance between the Shimano 105 and Ultegra components (both feel fantastic). But, where I can feel a big difference is in the 2 lb weight reduction on the SL6 over the SL5.

Pick the bikes up, one in each hand, and you’ll be able to feel the 32-ounce difference. Get them out on the road and you’ll really start to notice the weight decrease. Those 2 lbs will convert to extra speed, seconds knocked off, and more PBs. On climbs, you’ll feel you’ve got a spring in your step. On the flat, you’ll feel like you’ve got your own personal tailwind following you.

Will you feel like a superhero on the SL6? It’s possible, but don’t start wearing your bright red underpants on the outside of your bib tights.

Because of that weight difference, the SL6 will feel like a big step up from the SL5.

And it’s not just me who thinks that. Customer reviews talk about the silky smooth feel of the SL6, the benefits of the aero styling, and the beautiful design. One even said that it, “forces you to ride fast”. No bad thing.

In fact, the only downsides were that the handlebars weren’t felt to be aero enough, and “haven’t found any so far”. Which all sounds perfectly fine to me.

There is much debate amongst road bikers as to the benefits or otherwise of disc brakes over rim brakes. The entire Émonda range now has disc brakes, with the SL6’s Ultegra brakes being, in a word, sweet. My view is this. There may be a slight overall weight increase for the disc brakes vs rim brakes / reinforced wheel rims setup. But, the benefit you get from those disc brakes when you hit a patch of slippery stuff and pull your brakes whilst taking a hairpin bend on a steep and fast descent…is best measurable in terms of the number of packs of band aids you’ll need to apply in sticking yourself back together again.

I know that disc brakes are “on-trend” right now. In five years time we might be told that we need to switch back to rim brakes. But, frankly, I’m keeping the discs so I can slow down and stop when and where I need to.

Conclusion – which one to go for?

I really like the Émonda range and I really, really like the SL5 and SL6. The SL5 is substantially cheaper than the SL6 and, with the Shimano 105 drivetrain and brakes, it’s a fantastic and great value bike that will climb fast and barrel along the flat.

2 lbs is a lot of weight and that’s a deal-clincher for me. I can’t feel a performance difference between 105 and Ultegra, but I can really feel a difference of 2 lbs. The SL6 will get you up hills faster than the SL5 and will beat the SL5 on the flat. That, for me, is worth the price difference and it makes the SL6 my bike of choice from these two excellent machines.

The podium awaits.

Scott vs Specialized carbon fiber

Scott high modulus carbon.

Scott implements two primary types of carbon fiber technology in their bicycle frame construction; HMX-SL , HMX , and HMF carbon.

• HMX-SL ( High Modulus Xtreme, Super Light ) carbon is the pinnacle of Scott’s carbon fiber technology. This innovative blend of carbon fiber is designed for ultimate stiffness and minimal weight. Scott uses HMX-SL Carbon in their highest-end models, such as the premium version of the Scott Addict RC Ultimate and Foil RC Ultimate road bike. These bikes, with HMX-SL Carbon frames, are the go-to choice for professional cyclists competing in world-class races.
• HMX carbon is a level below the HMX-SL, and is still a top-tier carbon material offering a fantastic blend of stiffness and lightweight construction, albeit not as light or rigid as the HMX-SL. It’s an excellent choice for serious and experienced cyclists looking for a high-performance bike without the additional premium.
• HMF ( High Modulus Fiber ) carbon, may not be as light or stiff as HMX carbon, but it’s still a superior material that contributes to a robust, light, and efficient ride. Scott uses HMF carbon in their bikes that strike a balance between affordability and performance.

Specialized FACT Carbon

Specialized FACT (Functional Advanced Composite Technology) is an advanced carbon fiber technology used in high-performance Specialized bicycles. It offers a lightweight yet strong frame construction with precise carbon layup, resulting in optimal strength-to-weight ratio and improved ride quality. 

FACT carbon frames are engineered to efficiently transfer power, absorb road vibrations, and provide a comfortable riding experience. With continuous innovation and refinement, FACT Carbon demonstrates Specialized’s commitment to delivering top-notch performance and enhancing the overall cycling experience.

The carbon is available in three grades. The choice between FACT 12r , 11r , or 10r carbon depends on the bike model, your preferences, riding style, and budget.

• Specialized FACT 12r Carbon is the highest-grade carbon used by Specialized. Bikes (S-Works models) with frames made from FACT 12r carbon are the lightest and stiffest in the Specialized line-up . These frames are manufactured using the most advanced techniques and materials.
• Specialized FACT 11r Carbon used to be the highest-grade carbon until the S-Works Tarmac (SL5). Today, it’s the highest-grade carbon for the S-Works Roubaix.
• Specialized FACT 10r Carbon is two steps below 12r in the Specialized carbon hierarchy. While it doesn’t provide quite the same level of weight savings and stiffness as 12r, 10r frames are still very light and stiff, providing a high level of performance. FACT 10r carbon is used in all non S-Works models and is ideal for riders who want a balance of performance and value.

Frameset technologies and innovations

Scott Addict RC and Specialized Tarmac SL7 framesets incorporate advanced technologies to enhance their bikes’ performance and ride characteristics.
