What's new on the 2023 Trek Fuel EX?

Check out the Trek Fuel EX overview below and learn about all its exciting updates.

Trek Fuel Ex has 150/140mm of travel

More front and rear travel

Year after year, riders continue to push the limits of trail bikes and the Fuel EX Gen 6 delivers longer travel suspension for dominating steeper terrain. 

Front travel increases from 130mm to 140mm and the rear shock provides 150mm of cushion, up from 140mm on the previous model.

Trek Fuel EX now has 6 geo settings

Adjustable Geometry

The 2023 Fuel EX also introduces an innovative adjustable headset that can alter the head tube angle by +/- 1 degree depending on the desired slackness. 

The head tube angle can be set between 63.5 and 65.5 degrees. 

The angle adjust cups combine with the Mino Link for a total of 6 possible geometry configurations.

trek fuel geometry

Size specific builds

Trek has matched the frame sizes with appropriate wheel choices and chainstay lengths to ensure all riders achieve an ideal fit. 

XS models run nimble 27.5” wheels whereas frame sizes medium and up have 29ers. Small frames are available in both wheel options. 

All riders, regardless of their height, can find a bike that provides maximum control and handling.

trek fuel geometry

New frame features

The reimagined frame boasts trendy tech, including a full length downtube guard for protection from debris and tailgates during shuttle runs. 

The new threaded BB and guided internal routing keep everything neatly tucked away and low-maintenance. 

The larger 34.6mm seat tube accommodates sturdier dropper posts and now all frames— carbon and alloy— come with handy downtube storage .

trek fuel geometry

Adjustable suspension progression

Riders can effortlessly switch between suspension settings via a flip chip on the lower shock mount. 

Choose between the plush, less progressive setting for better trail feedback or the more progressive setting that’s better for aggressive riding. 

The progressive option avoids bottoming-out and performs great with linear coil shocks if you choose to upgrade later on.

Trek Fuel EX Geometry

The new Fuel EX features a steeper seat angle and longer reach for more efficient climbing and improved handling on demanding descents. 

This more aggressive geometry can be further fine-tuned from inside the headset with angle adjust cups (sold separately) as well as the rear triangle Mino Link, r esulting in 6 different geo configurations .

Trek Fuel EX Size Chart

Trek outfitted each frame option with the correct wheel size to optimize handling. XS models come with 27.5” wheels, frames M and up run 29ers. People who ride S frames are often caught in the middle, so those frames are available with both wheel options.

*Size XXL available in alloy only.

Adjustability and Customization

Adjustability and Customization

By adjusting the Mino Link, riders can tailor the bike’s handling to their preferences, with a higher link position providing a more agile ride and a lower link position offering increased stability. This system offers a significant advantage for riders who want to fine-tune their bike’s performance for different riding styles and terrains.

Additionally, both the Fuel EX and Top Fuel feature adjustable headsets, which allow riders to fine-tune the bike’s handling and responsiveness. This adjustment can be made by changing the headset spacers, which can alter the fork’s rake and steering geometry.

In conclusion, the Trek Fuel EX and Top Fuel offer a high degree of adjustability and customization, allowing riders to tailor their bikes to their specific needs and preferences. The Mino Link adjustment system, combined with adjustable headsets, provides riders with the flexibility to fine-tune their bikes for various riding styles and terrains, ensuring a personalized and optimized riding experience.

The Mino Link adjustment on Trek Fuel EX and Top Fuel mountain bikes allows riders to fine-tune their geometry and suspension settings to suit their riding style and preferences.

This feature is designed to enhance the performance of these iconic bikes, making them more versatile and adaptable to a wide range of terrains and rider skill levels.

By adjusting the Mino Link, riders can create a more customized ride experience, tailored to their needs and preferences.

This level of adjustability and customization is a key factor in the success of these bikes, setting them apart in the ever-evolving world of mountain biking.

The adjustability of the headset and suspension on Trek’s Fuel EX and Top Fuel mountain bikes is a key feature that sets these models apart. Both bikes offer a range of adjustments to cater to different rider preferences and trail conditions.

Headset Adjustability : The new Fuel EX features headset cups that allow riders to run the bike as slack as 63.5-degrees or as steep as 66-degrees, providing more options for riders to fine-tune the bike’s handling.

Suspension Tuning : The Fuel EX’s suspension system has been updated with coil-shock compatibility and flip-chip pivot hardware, enabling riders to adjust the bike’s performance according to their needs.

Internal cable routing is a topic that sparks heated debates among cyclists. Some argue that it enhances the look of a bike, while others claim it compromises serviceability and maintenance. Trek’s Control Freak cable routing system, which is used in the Fuel EX and Top Fuel models, has been a subject of discussion among riders.

Internal cable routing can be a challenge when it comes to maintenance. For instance, on the Fuel EX, riders often have to remove the cranks and bottom bracket to access the cable entry points. This can be time-consuming and may require specialized tools. Additionally, internal routing can lead to noise due to cables rattling around inside frame tubes.

However, Trek’s Control Freak system aims to address these issues by providing a versatile solution for cable management. The system allows for quiet and efficient cable routing, ensuring that cables are securely tucked away and not exposed to the elements.

This can help reduce the risk of cable damage and improve the overall durability of the bike.

When it comes to cable replacement, internal routing may require more effort. Riders may need to remove parts of the frame or use specialized tools to access the cables.

In conclusion, internal cable routing can be a double-edged sword. While it may enhance the aesthetic appeal of a bike, it can also pose challenges when it comes to maintenance and serviceability. Trek’s Control Freak system aims to mitigate these issues, providing a more efficient and durable solution for cable management on their mountain bikes.

Comparing Price and Value

The Trek Fuel EX is known for its ability to handle a wide range of terrain, from XC races to more demanding downhill trails. It features a more aggressive geometry, with a longer reach and steeper head tube angle, which provides better stability and control on descents.

Additionally, the Fuel EX offers a wider range of component options, including high-end suspension systems and drivetrains, which can increase its overall value for riders seeking more capability and customization.

On the other hand, the Trek Top Fuel is designed with a more balanced geometry, catering to riders who prioritize efficiency and agility on XC trails. Its lighter frame and efficient suspension system make it an excellent choice for riders who want a bike that can climb well and maintain speed on long, flat sections.

The Top Fuel also offers a more streamlined component spec, which can make it a more affordable option for riders who don’t require the same level of customization as the Fuel EX.

When considering the price and value of these bikes, it’s essential to weigh the benefits of each model against your personal riding style and preferences. If you’re looking for a bike that can handle a variety of terrain and offer more customization options, the Fuel EX may be the better choice.

However, if you prioritize efficiency and agility on XC trails, the Top Fuel could be a more cost-effective option.

Additionally, factors like resale value, financing options, long-term maintenance, and customer support should also be considered when comparing the price and value of these bikes. Researching these aspects can help you make an informed decision and ensure that you’re getting the best value for your investment.

Frequently Asked Questions (FAQs)

The Top Fuel shaves roughly 1-2 lbs off the Fuel EX’s weight. You’re trading travel and capability for a leaner, racier rig meant to fly up climbs.

You’ll fly over rocks as smoothly as a hovercraft with the Top Fuel’s straight-line RockShox suspension, while the Fuel EX’s four-bar system excels at absorbing big hits.

You’ll find a wider range of handlebar widths and rises on the Fuel EX for greater control and comfort on rugged trails. The Top Fuel typically has narrower, lower bars tuned for cross-country performance.

You’ll be pleasantly surprised – the Fuel EX offers top-tier performance at a more wallet-friendly price than the premium Top Fuel.

You’ll fit the Top Fuel if you’re 5’3-6’5, and the Fuel EX for 5’4-6’ Trek tailors each bike’s geometry to rider height, prioritizing an optimal fit and riding experience.

Whether you’re an adrenaline junkie conquering gnarly descents or a climber hungry for steep ascents, the Trek Fuel EX vs Top Fuel showdown unveils impressive capabilities. These iconic MTBs deliver unparalleled performance, combining cutting-edge suspension wizardry with adaptable geometry.

Ultimately, your riding style and terrain preferences will determine which machine best complements your thirst for singletrack domination.

2022 Trek Top Fuel Review | All-new frame & geometry, with a whole new attitude

The not-so-minor details, 2022 trek top fuel 9.8 xt.

https://www.trekbikes.com/

- Brilliant trail-ripping geometry - Active and supportive suspension - Masses of cornering grip & stability - Refined and practical frame design - Downtube storage is a welcome addition

- Dropper post is sluggish - Wheels are solid but quite heavy - Carbon bars are harsh - Heavier than many of its competitors

Flow reviews the 2022 Trek Top Fuel

The Trek Top Fuel has long been known as the American brand’s flagship full suspension XC race bike, purpose-built to to compete at the very highest level of the sport. In more recent years however, the Top Fuel has steered in a different direction. With the short-travel Supercaliber taking over duties for World Cup XCO racing, Trek has softened the Top Fuel’s serious, race-focused persona, adding travel and bulking it up in the process.

For 2022, the Trek Top Fuel makes its biggest move away from its XC racing roots. Equipped with a brand new frame, an updated suspension design and some thoroughly modern geometry, the Top Fuel aims to retain the pert pedalling performance of its predecessor while significantly boosting its all-round capability. So, has Trek succeeded?

Watch our video review of the new Trek Top Fuel here:

2022 trek top fuel 9.8 xt

Along with the active ABP suspension design and chunky tyres, there’s an exceptional amount of grip and support on offer for a 120mm travel bike.

2022 trek top fuel 9.8 xt

Trek Top Fuel overview

Despite being all-new, the Trek Top Fuel retains its position in between the Supercaliber (the 60mm travel XC race bike) and the Fuel EX (the 130mm travel trail bike).

It’s equipped with a 120mm travel fork just like its predecessor, but rear travel has actually lifted by 5mm up to 120mm. This increase has been achieved with a longer stroke shock (50mm vs 45mm), and Trek has also flipped the orientation of the trunnion-mount. The rocker link now drives the shock via two sealed cartridge bearings to improve sensitivity.

You’ll no longer find a dual remote lockout on the Top Fuel, which leads to a vastly cleaner bike with fewer cables occupying your view from the cockpit. Along with the bigger shock, slacker geometry and 2.4in wide tyres, it is without doubt the most trail-oriented Top Fuel we’ve seen yet.

To put it into context, that sees it move away from the likes of the Orbea Oiz TR and the Canyon Lux Trail , and more towards the direction of the Santa Cruz Tallboy and Pivot Trail 429 .

2022 trek top fuel 9.8 xt

A new, burlier chassis

Though it looks pretty similar, the Trek Top Fuel frame is all-new for 2022. It’s not so much a radical overhaul, but rather a collection of many small refinements that add up to a more practical package.

The chassis is notably beefier than its predecessor, with the seat tube diameter swelling to the new-school 34.9mm size. As well as increasing frame stiffness, the fatter seat tube is also shorter, allowing it to swallow a modern long-stroke dropper post.

The downtube is also larger, and it now features the integrated storage design we’ve seen employed on the latest Fuel EX and Slash. A latch underneath the bottle cage removes the trap door, providing you access within. A neat tool roll is included with the bike so you can carry a spare tube, levers and CO2. You could also fit a lightweight jacket in there along with some snacks.

2022 trek top fuel 9.8 xt

Trek has updated the Knock Block headset, increasing the available turning radius from 58° to 72°. This provides you with greater freedom of movement on the trail, but still prevents the handlebar controls from smashing into the top tube. If you’re not into it though, the Knock Block is removable.

Also nice to see is a threaded bottom bracket shell for ease of maintenance, and the rear ABP pivot can now be tightened with a cassette tool. Also new for the Top Fuel is guided internal cable routing – poke the cable in at one end, and it’ll pop out the other, no fishing required.

Trail-leaning geometry

The 2022 Trek Top Fuel has received a series of geometry updates over the outgoing model, bringing it up to speed with other boundary-pushers in this travel bracket. Here are the key numbers;

  • Head tube angle: 66°
  • Seat tube angle: 76°
  • Reach: 420mm (S), 450mm (M), 465mm (M/L), 480mm (L), 500mm (XL)
  • Rear centre length: 435mm
  • BB drop: 36mm

Compared to the old Top Fuel, the head angle has kicked back by 1.5-degrees and the reach measurements have gone up by 10mm. The seat tube angle has also steepened by 1-degree to improve the climbing position, while the chainstay length and BB drop remain the same.

The Top Fuel still features a Mino Link, but it’s now located at the lower shock eyelet. Bikes will come setup from the factory in the Low position. Flipping that into High will lift the BB height by 7mm and steepen the angles by 0.4°.

You can get even rowdier by fitting a 130mm travel fork, which will kick the head angle back to a very-slack 65.6° in the Low position. And for those wanting to push the needle further, there’s clearance to run 2.5in tyres.

This differs from some other brands that utilise a single frame, and simply up-fork and up-shock it to create a slightly longer travel bike (like the Specialized Epic EVO and Orbea Oiz TR). The Top Fuel is not one of those bikes.

Trek Top Fuel sizing & fit

We put the new Trek Top Fuel into the hands of our tester Ben, who owns the current Top Fuel and has also spent considerable time on the Fuel EX. At 181cm tall, Ben’s been riding a size Large across all three bikes.

The Top Fuel is well-proportioned out of the box. The 480mm reach is very long, but it’s balanced nicely with a 50mm stem and the 76° seat tube angle. The Bontrager saddle is totally inoffensive, and we haven’t needed to shunt it into an extreme position just to get it comfortable.

The 760mm wide riser bars are a great match for this bike, and while it may not be totally necessary for all riders, the 170mm stroke dropper post is fashionably long for such a short travel bike.

Suspension & tyre setup

With the anodised sag gradients on the fork and shock, suspension setup is made easy. Weighing 80kg loaded up, Ben’s been running 180psi in the rear shock (26% sag) 80psi in the fork (20% sag).

The factory rebound tune for both the RockShox SID fork and Deluxe shock is quite light, so each rebound dial was set a couple of clicks slower than halfway.

Tubeless rim strips and valves come pre-fitted to the Bontrager wheels, and Trek kindly includes two bottles of sealant with the bike, making tubeless setup the breeze it should be. Pressures were set at 20psi on the front and 22psi on the rear.

Trek Top Fuel weight

Given its swollen proportions, the new Trek Top Fuel has gotten heavier. With the tyres setup tubeless, our test bike came in at 12.88kg without pedals. To put that number into perspective, here’s how it compares to some similarly-priced XC and Trail bikes we’ve recently tested;

  • Canyon Lux Trail CF 9 – 11.22kg
  • Merida Ninety-Six 8000 – 11.63kg
  • Scott Spark 910 – 12.43kg
  • Specialized Stumpjumper Pro – 12.84kg
  • Trek Top Fuel 9.8 XT – 12.88kg
  • Giant Trance Advamced Pro 29 1 – 13.38kg

trek top fuel 2022 9.8 xt

Trek claims a carbon Top Fuel frame weighs 2.7kg including the rear shock, which puts it on the heavier side of things for a 120mm travel bike. The alloy frame is purportedly a whole kilo heavier again, with a claimed weight of 3.74kg.

The Top Fuel’s rolling stock is also a significant contributor to its overall mass. The Bontrager Line Elite wheels are heavy at 2,071g for the pair (with tubeless strips and valves). Incidentally, these are exactly the same wheels that came on the Slash 9.9 X01 , which is a full-bore enduro race bike.

Trek has also plumped up the rubber. The previous Top Fuel featured semi-slick XR3 tyres, but the new bike is now spec’d with 2.4in wide XR4 Team Issue tyres. They’re not overly heavy at around 800g each, though they do offer significantly better grip across a broader range of conditions.

2022 trek top fuel 9.8 xt

What does the Trek Top Fuel do well?

From the very first ride the new Trek Top Fuel proved to be easy to get used to, with no quirks to the fit, handling or suspension.

The proportions are significantly broader compared to the outgoing Top Fuel, with the front wheel sticking out much further ahead of the rider. Despite the long reach however, the effective top tube length is basically identical to its predecessor, so the overall cockpit length remains the same.

The steeper seat angle is noticeable though, providing an improved climbing position with your hips placed further over the bottom bracket. As a result, less bum-shuffling is required on stem-chewing ascents.

Pedalling performance is also superb. Despite its burlier exterior, Trek is still prioritising pedal efficiency with the Top Fuel, with the main pivot positioned high and quite far forward of the bottom bracket. Anti-squat is claimed to hover around the 100% mark, and indeed the rear suspension clenches tightly under chain torque, propelling the whole bike forward with minimal energy loss.

2022 trek top fuel 9.8 xt

Active suspension performance

Despite the trunnion bearing mount and the longer shock stroke, the rear suspension doesn’t feel radically plusher than its predecessor, which already offered great performance. It is noticeably more supportive though, particularly when absorbing square-edge hits at speed, and when returning to earth after boosting off a lip on the trail.

It’s worth noting here that many bikes in the 100-130mm travel bracket make use of a carbon flex-stay design, including the Canyon Lux Trail, Merida Ninety-Six, and Specialized Stumpjumper. As well as being simpler, flex-stay designs are typically lighter too.

canyon lux trail cf 9

In comparison, the Top Fuel sticks with a genuine four-bar platform based around the ABP suspension design. Trek claims the ABP pivot helps to isolate braking forces from the suspension, and indeed it does result in less skipping and skidding when you’re on the brakes on loose, rocky descents.

With all the pivot points rolling on steel ball bearings, the suspension is more active and possesses a more consistent feel to both compression and rebound damping when compared to a flex-stay design. Yes it’s heavier, but the Top Fuel offers notably more active suspension performance, with excellent traction on loose climbs and better reactivity across chattery rock gardens. It’s very impressive for a 120mm travel bike.

2022 trek top fuel 9.8 xt

Look out Fuel EX!

The geometry is also brilliant, and the handling really sets it apart from the outgoing Top Fuel.

Cornering performance has improved, with more grip courtesy of the longer front end and those XR4 tyres. These are great all-rounders, with a supple casing and surprisingly decent rolling speed given their size and tread pattern.

2022 trek top fuel 9.8 xt

The new Top Fuel is also much more composed on rough and fast descents. Thanks to the longer reach and slacker head angle, the overall wheelbase length has grown by almost 40mm. That’s huge, and it offers a vastly more planted feel at speed. Along with the big tyres and active suspension, this really is a solid little trail bike.

In fact, the geometry updates kind of make the Fuel EX look a little outdated. The two bikes now share the same head angle, and the Top Fuel has a 10mm longer reach and a steeper seat angle. The front end is quite a bit higher on the Fuel EX though, and that does inspire more confidence on really steep descents.

As mentioned earlier though, it’s possible to fit a 130mm fork to the Top Fuel, which would lift the front end and actually make it slacker than the Fuel EX. Indeed there’s now quite a bit of overlap between the two platforms, leaving us to ponder what could be in store for the next generation Fuel EX.

2022 trek top fuel 9.8 xt

What does it struggle with?

You’ve likely gathered that the new Trek Top Fuel is more of a muscly trail ripper than a spindly XC featherweight. While it may carry over the name, it’s evolved into quite a different bike compared to its racier ancestors.

The lack of a remote lockout results in a much cleaner cockpit, and we like how it signals the Top Fuel’s commitment to its trail riding intentions. However, it may disappoint those riders and racers who prefer having an instantaneous sprint button at their fingertips.

Indeed with all the updates, and the fact that the new Top Fuel has double the travel of the Supercaliber, there is now an even bigger gap between these two bikes. Riders who are still interested in some part-time XC racing, but aren’t sold on the Supercaliber’s sharp geometry and proprietary IsoStrut suspension design, may be turned off by the Top Fuel’s new attitude.

2022 trek top fuel 9.8 xt bontrager line elite carbon wheel xr4 team issue tyre

Of course you could easily inject some speed with some lighter and faster-rolling tyres, like Bontrager’s XR2. There’s also around half a kilo to be saved in the wheelset, which would make a significant difference to the Top Fuel’s acceleration and climbing enthusiasm.

You could also flip the Mino Link into the High position to steepen the angles. In that guise, with lighter wheels and faster tyres, the Top Fuel would make for a comfortable and confidence-inspiring option for those wanting to sign up for the odd endurance race or multi-day event. If you’re serious about your XC racing though, this is not the bike for you – you’ll be wanting to look at the stupendously efficient Supercaliber for such endeavours.

2022 trek top fuel 9.8 xt

Component highs & lows

The 2022 Trek Fuel 9.8 XT is a solid package out of the box, especially when you consider it comes in $1,600 cheaper than the 2021 model. And that’s with a pretty much identical build kit. How has a new bike gotten cheaper in the midst of a global pandemic and industry-wide component shortages? Heck knows!

There’s not a lot to be said about the Shimano XT groupset – it works, it’s solid, and it’s easy to tune. The I-Spec mounts offer plenty of adjustability for getting the brake and shift levers into the right spot, and the integrated dropper lever is a nice touch too.

The RockShox suspension isn’t quite as sensitive as the Fox equivalent, particularly the SID Select+ fork, which felt a little stickier than we expected. Otherwise the fork and shock perform well, and the ease of setup is great.

2022 trek top fuel 9.8 xt

The Bontrager dropper post works fine, but the action is sluggish compared to some of its competitors. And while the carbon handlebars offer a nice profile, having spent a lot of time on OneUp handlebars lately, the Bontrager Line Pro feels considerably harsher in comparison.

We’ve had excellent long-term experience with Bontrager’s latest Line Pro & Line Elite carbon wheels , which feature thick carbon beads that are designed to increase impact strength while also reducing the chance of pinch-flats. They’re totally solid and come with an excellent crash-replacement guarantee, while the buzzy 108pt engagement freehub delivers rapid pickup at the pedals. As mentioned earlier though, they are heavy, providing an opportunity to drop significant weight with a wheel upgrade.

Otherwise we’ve been impressed with the frame finish so far. The Mino Link is simple and effective, the Knock Block is totally unnoticeable on the trail, and we’re big fans of the built-in storage from the Burrito Box. Or is it the Kebab Cave? Maybe a Sausage Roll Hole? Sushi Shaft? Cannoli Cavity? Hot Dog Hollow? Spring Roll Room?

Alright, alright! We’ll show ourselves the door…the door that leads into the Spring Roll Room – ha!

2022 trek top fuel 9.8 xt

Flow’s Verdict

Tying together a whole suite of updates to the frame and suspension design, there are no doubts that the new Trek Top Fuel is a more capable bike than its predecessor. It’s still very efficient, but having adopted a more progressive approach to its geometry, it delivers a significant improvement in stability. Along with the active ABP suspension design and chunky tyres, there’s an exceptional amount of grip and support on offer for a 120mm travel bike.

With all those changes, the Top Fuel moves even further away from the Supercaliber. And for some riders, that gap will be a little too wide.

Trek seems happy to have a clear delineation between the two platforms though. This differs from some other brands that utilise a single frame, and simply up-fork and up-shock it to create a slightly longer travel bike (like the Specialized Epic EVO and Orbea Oiz TR). The Top Fuel is not one of those bikes.

Instead of being a long-legged Supercaliber, it’s really a shrunken-down Fuel EX, albeit one with more contemporary geometry. And having ridden both bikes, unless you really need the extra travel of the Fuel EX, this is arguably the better option.

Sure it may have put off the weight-weenies and lockout-lovers, but there’s no denying that the Top Fuel has broadened its appeal to an even wider range of riders, and we reckon it’s more fun as a result.

For the first time Rosatom Fuel Division supplied fresh nuclear fuel to the world’s only floating nuclear cogeneration plant in the Arctic

The fuel was supplied to the northernmost town of Russia along the Northern Sea Route.

trek fuel geometry

The first in the history of the power plant refueling, that is, the replacement of spent nuclear fuel with fresh one, is planned to begin before 2024. The manufacturer of nuclear fuel for all Russian nuclear icebreakers, as well as the Akademik Lomonosov FNPP, is Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC), a company of Rosatom Fuel Company TVEL that is based in Elektrostal, Moscow Region.

The FNPP includes two KLT-40S reactors of the icebreaking type. Unlike convenient ground-based large reactors (that require partial replacement of fuel rods once every 12-18 months), in the case of these reactors, the refueling takes place once every few years and includes unloading of the entire reactor core and loading of fresh fuel into the reactor.

The cores of KLT-40 reactors of the Akademik Lomonosov floating power unit have a number of advantages compared to the reference ones: a cassette core was used for the first time in the history of the unit, which made it possible to increase the fuel energy resource to 3-3.5 years between refuelings, and also reduce the fuel component of the electricity cost by one and a half times. The FNPP operating experience formed the basis for the designs of reactors for nuclear icebreakers of the newest series 22220. Three such icebreakers have been launched by now.

For the first time the power units of the Akademik Lomonosov floating nuclear power plant were connected to the grid in December 2019, and put into commercial operation in May 2020. The supply of nuclear fuel from Elektrostal to Pevek and its loading into the second reactor is planned for 2024. The total power of the Akademik Lomonosov FNPP, supplied to the coastal grid of Pevek without thermal energy consumption on shore, is about 76 MW, being about 44 MW in the maximum thermal power supply mode. The FNPP generated 194 million kWh according to the results of 2023. The population of Pevek is just a little more than 4 thousand, while the FNPP has a potential for supplying electricity to a city with a population of up to 100 thousand people. After the FNPP commissioning two goals were achieved. These include first of all the replacement of the retiring capacities of the Bilibino NPP, which has been operating since 1974, as well as the Chaunskaya TPP, which has already been operating for more than 70 years. Secondly, energy is supplied to the main mining companies in western Chukotka in the Chaun-Bilibino energy hub a large ore and metal cluster, including gold mining companies and projects related to the development of the Baimsk ore zone. In September 2023, a 110 kilovolt power transmission line with a length of 490 kilometers was put into operation, connecting the towns of Pevek and Bilibino. The line increased the reliability of energy supply from the FNPP to both Bilibino consumers and mining companies, the largest of which is the Baimsky GOK. The comprehensive development of the Russian Arctic is a national strategic priority. To increase the NSR traffic is of paramount importance for accomplishment of the tasks set in the field of cargo shipping. This logistics corridor is being developed due regular freight voyages, construction of new nuclear-powered icebreakers and modernization of the relevant infrastructure. Rosatom companies are actively involved in this work. Rosatom Fuel Company TVEL (Rosatom Fuel Division) includes companies fabricating nuclear fuel, converting and enriching uranium, manufacturing gas centrifuges, conducting researches and producing designs. As the only nuclear fuel supplier to Russian NPPs, TVEL supplies fuel for a total of 75 power reactors in 15 countries, for research reactors in nine countries, as well as for propulsion reactors of the Russian nuclear fleet. Every sixth power reactor in the world runs on TVEL fuel. Rosatom Fuel Division is the world’s largest producer of enriched uranium and the leader on the global stable isotope market. The Fuel Division is actively developing new businesses in chemistry, metallurgy, energy storage technologies, 3D printing, digital products, and decommissioning of nuclear facilities. TVEL also includes Rosatom integrators for additive technologies and electricity storage systems. Rosenergoatom, Joint-Stock Company is part of Rosatom Electric Power Division and one of the largest companies in the industry acting as an operator of nuclear power plants. It includes, as its branches, 11 operating NPPs, including the FNPP, the Scientific and Technical Center for Emergency Operations at NPPs, Design and Engineering as well as Technological companies. In total, 37 power units with a total installed capacity of over 29.5 GW are in operation at 11 nuclear power plants in Russia. Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC, Elektrostal) is one of the world’s largest manufacturers of fuel for nuclear power plants. The company produces fuel assemblies for VVER-440, VVER-1000, RBMK-1000, BN-600,800, VK-50, EGP-6; powders and fuel pellets intended for supply to foreign customers. It also produces nuclear fuel for research reactors. The plant belongs to the TVEL Fuel Company of Rosatom.

Complex experimental studies of hydrodynamically excited vibrations of fuel-element bundles have been performed on full-scale models of VVER-440 fuel assemblies. Pressure pulsations were used as the main hydrodynamic characteristic of turbulent coolant flow according to the effect of its load on the fuel-element surfaces in the flow. Realizations of the random hydrodynamic loads causing vibrations of fuel elements are obtained on the basis of multi-point measurements of pressure pulsations along the perimeter of the outer row of the fuels elements in a bundle.

Business at the front, party at the back

Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. The Fuel EX is mullet-ready, just throw Mino Link into high, toss on a 160 mm fork and get ready to party.

Adjustable Leverage Rate

Easily adjust suspension progression with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails loaded with square-edge bumps. Flip it to More progressive when you’re riding fast, hitting big features and don’t want to bottom out – or if you want to roll with a coil shock.

Sized for every rider Whether your head is above the clouds, or you stand at a lower altitude, the Fuel EX’s huge size range provides an outstanding fit for every rider. If you fall between XS and XXL, you’ll be ready to saddle up with size-appropriate wheels and chain stay lengths for a ride that’s fine tuned to you no matter your height.

The slack and stable 64.5-degree head tube angle complements the longer-travel suspension for more confidence.

A steeper, 77.2-degree seat tube keeps you perched for pedalling efficiency on long fire roads and quick, punchy climbs.

Longer reach compensates for the steeper seat tube, so you stay comfortable in the cockpit and ready for what’s around the corner.

Size-specific chain stays give smaller riders more nimble handling, while taller riders get better front wheel traction on climbs.

New frame, new possibilities

The Fuel EX’s new generation opens up possibilities for riders who want full customisation. Broader shock compatibility allows for more aftermarket upgrades, like coil shocks. A larger 34.9 mm seat tube accommodates larger, more robust dropper posts.

Non-stop suspension

Trek’s exclusive Active Braking Pivot keeps your suspension active while you’re braking (which is often when you need it most).

Clean and easy

Internal routing tunnels eliminate cable rattle and simplify maintenance along with a robust threaded BB. A bolt-on downtube and chain stay guards protect against rock strikes and shuttle damage while muting noise from the trail.

Stow it, don’t show it

Sometimes less is more. The Top Fuel is a shorter-travel full-suspension down-country bike ready for all-day pedal-fests. It’s just as happy hammering out miles on smooth-rolling cross-country singletrack as it is dipping over the backside of the mountain to explore off-the-beaten-track adventures.

Want to go bigger? The Slash is a long-travel trail bike that looks like a monster truck and rides like a magic carpet. It’s built for big all-mountain terrain, racing the clock on rugged enduro lines and having a rip-roaring good time in the rough.
