At a glance

Top Fuel 8 is a high-performance, high-value full suspension cross country mountain bike. It’s built for speed and efficiency in rough singletrack and XC races. A lightweight Alpha Aluminum frame, a 1×12 drivetrain, and Tubeless Ready wheels make it a great choice for new racers, fast singletrack riders, and anyone who wants to ride fast on trails without breaking the bank.

Where To Buy

Trek Logo

"Super light and fast as hell"

"The new Top Fuel might not be a pure XC-race bike anymore, but it's still precise and very fast. Its new trail orientation makes it a great choice for a rider who wants a fast and light bike with most of the the efficiency of a cross-country race bike, but with bit more versatility and playfulness."

"More than just race-winning performance"

"It's a seriously rapid bike, and it responds well to roots and rocks, allowing you to keep the power on rather than having to ease back. It manages a fine line between a taut and lithe XC race machine and a bike that most riders would be happy to use for general trail duty."

"Racing blood, trail spirit"

"It's devilishly quick, accelerates in a way that makes it seem like my legs actually produce real power. It's stable, planted, and it tracks like it's supposed to. Endurance athletes will be able to remain seated over more terrain, saving precious energy over the long haul, while XC pinners will hook up better on steep technical climbs."

My history of mountain biking started with a little wooden trike, with no pedals and wheels bigger than my head. I moved forward as any child does onto a bigger bike with bigger wheels and pedals. My parents always encouraged me to get outside and ride a bike, although I didn’t like the idea of mountain biking. I knew how to ride a bike; why go any further?

A few days before the Riva del Garda Bike Festival we were invited to the official presentation of the new Top Fuel, Trek’s full-suspension XC / Trail weapon. You read that right, I also entered the word “Trail”, as this is how the bike was presented. Compared to the previous version it is defined as a more versatile bike, made with more balanced geometry and a lower weight. Let’s start with geometry. In the following images you can easily pick up on what the actual changes made to the frame were. It is easy to understand how they wanted to change the soul of the bike,

The Top Fuel design changes are in response to changing OXC course features and the upcoming Olympics - preparing its athletes for the demands of battling the fastest mountain bikers on earth. - Mtbr.com

Trek Top Fuel 9.8

The Trek Top Fuel 9.8 SL Is a Purebred XC Race Bike

A lightweight frame and carbon wheels make this bike fly

In a world full of trail bikes and long-travel enduro bikes that are made to blast over anything in their path, the Top Fuel 9.8 SL stands out as a no-compromise XC race bike aimed at the go-fast everywhere (not just go-fast downhill) crowd. The OCLV carbon frame rolls on carbon Bontrager Kovee Elite 30 hoops, and the 2.2-inch Bontrager XR2 tires have minimal tread—just enough to grab the trail without adding unnecessary rolling resistance. Shimano XT brakes and SRAM GX Eagle drivetrain give the type of high-end performance you'd expect on a dream bike without the premium price tag that typically goes along with it. Bontrager carbon handlebars and seat post, paired with a Bontrager Montrose Elite saddle with titanium rails, shave a few more grams and complete this lust-worthy build.

Solid and responsive to pedaling input, the bike is a pleasure to ride uphill, both on rough, technical terrain and, thanks to the Twistloc remote that locks out both the fork and the shock, on paved climbs as well. On the trails you get balanced handling that gives you a feeling of stability while also being incredibly nimble when you're navigating tight, slow turns. This is an XC racer's dream bike that comes at a reasonable price.

Full Floater EVO Link Suspension

The rear shock floats between two shock mounts and gets compressed at both ends.

Smooth, Fast Suspension

The Top Fuel 9.8 boasts the same OCLV carbon main frame and seat stays as Trek's flagship XC bike, the Top Fuel 9.9 SL, the only difference is that this one has aluminum chain stays instead of carbon. The RockShox SID RL fork boasts 100mm of smooth travel, and the Fox Performance Elite shock is nestled into Trek's Full Floater, EVO Link suspension and provides 100mm of travel at the rear wheel. Both the fork and the shock have remote lockouts, activated by the Twistloc remote on the handlebar.

Trek Top Fuel 9.8

The design, which uses a pivot that rotates around the rear axle feels efficient and smooth, especially on rough terrain, where it helps the rear wheel find extra traction. That means you can worry less about your wheels slipping and stay on the gas longer in many situations, potentially gaining seconds on your rivals. Instead of connecting one end of the shock to a fixed point, like on many other suspension designs, Trek attaches it to pivots at both ends. That's what it calls Full Floater, and it gives engineers a little more latitude when plotting the kinematics to find a better balance between bump absorption and crisp pedaling. And in situation where you need even more efficiency, you can lock completely lock it out.

Components and Features that Standout

Trek blended Shimano XT hydraulic disc brakes with a SRAM GX Eagle 12-speed drivetrain , taking advantage of both the amazing power and modulation of Shimano brakes and the expanded gearing range of SRAM's 12-speed, that comes with a 10-50 cassette and 32t chain ring, paired with a set of Truvativ Stylo Carbon Eagle cranks. This combination gives you such a great range of gears you'll have everything you need to handle ripping fast downhills, fast dirt roads, and long, steep, lung-busting climbs where you need that 32 x 50 to get to the top without feeling your heart jumping out of your chest.

Trek Top Fuel 9.8

The Bontrager Kovee Elite 30 carbon wheels, shod in 2.2-inch Bontrager XR2 Team Issue tires are light, fast wheels made to haul ass through the woods. The tires have enough tread to be grippy when you need it, but not so much to slow you down on fast terrain. They're great on dry race courses and less so on wet, rocky, or muddy conditions. You might need a second set of tires if you plan on doing more trail riding with this bike. And you should. Even though this bike is built for speed it's also impressive, for a short-travel bike, on pretty gnarly terrain.

Top Fuel Family

The Top Fuel 9.9 SL ($9,300) is Trek's top-of-the-line XC bike, with a full carbon OCLV main frame and stays, RockShox SID SE carbon fork with 100mm of travel, Fox Factor Float DPS shock giving 100mm of travel at the rear wheel, and Bontrager Kovee Pro 30 carbon hoops. The Top Fuel 8 ($3,150) has an all aluminum frame, RockSox Recon RL 100mm fork, and a Fox Performance Float DPS shock providing 100mm of travel at the rear wheel.

Nimble, Steady Handling

The geometry on this bike is pretty much what you'd expect from a short-travel XC bike. My 21.5-inch test bike had a reach of 472mm and a stack height of 606mm, which is pretty consistent with similar bikes. Cannondale's Scalpel-Si is slightly shorter at 466mm of reach and slightly taller with a 615mm stack height. The Specialized S-Works Epic is even taller at 630mm, but only just over half a centimeter longer with 475mm of reach.

On paper the Top Fuel most closely mirrors the Scalpel-Si. The Top Fuel's wheel base is 1166mm, which is only 3mm shorter than the Scalpel-Si, bottom bracket drop is 39mm for the Trek and 38mm for the Cannondale, and even the trail is very close, with the Top Fuel having just 3om more trail at 80mm, compared to 77mm for the Scalpel-Si.

Trek Top Fuel

Riding (and Racing) the Top Fuel

This bike is made to go fast, and that's what it does best. That's not to say it isn't an absolute pleasure to take on a casual trail ride, but to ride this bike is to feel the urge to push it harder and faster, as the bike amazes with what it can handle. It offers tight but not twitchy steering, which is incredibly welcome while navigating slow, rocky singletrack.

Sharp, low-speed turns, both uphill and downhill, were very easy to navigate, and mid-turn line corrections weren't troublesome at all. As nimble as this bike is in the tight stuff, it tracks beautifully at high speed and lets you dig into and whip around bermed corners. And don't be afraid to get sendy on this bike, either. It may be a short-travel XC bike but this thing feels stable in the air and the suspension helped make landings seamless and smooth.

Over the course of the test, I kept pushing the bike harder and harder, testing the limits, until I actually found them much further from what I'd expect a bike this fast to be capable of. On numerous occasions I was ready for a trip over the bars when, to my surprise, the fork just absorbed it and the wheels kept rolling.

Even with the suspension set very soft to handle the rocky terrain we have in eastern PA, the bike pedaled smoothly with minimal bouncing. Even paved climbs weren't a drag thanks to convenient Twistloc dual remote lock-out. With both the fork and the shock locked out, the bike felt stiff and responsive, ready to sprint up a hill or off the start line chasing the hole shot. Anyone looking to step up their XC game without paying a small fortune should check out this bike.

Trek Top Fuel 9.8 review

Super-capable ripper on the racetrack or singletrack

Laurence Crossman-Emms

Ed Thomsett

Makes the climbs fun and rips on the way down; an elegant package with a choice of colours; the six frame sizes span a massive range

A higher front end would give more descending confidence; thin tyres don’t offer much grip or protection; carbon wheels and bar bump up the price without a big impact on performance

Trek’s ambition with the Top Fuel is to combine the best qualities of both cross-country and trail bikes. This genre-bending, 115mm-travel 29er is burlier than its XC thoroughbred, the Supercaliber , but lighter and more agile than the Fuel EX . It promises lightning-fast speeds, whether gravity is on your side or not.

Trek Top Fuel 9.8 frame

The Top Fuel’s full-carbon frame is obviously a Trek design, with that familiar twin-triangle shape and ABP (Active Braking Pivot) suspension design, where the rearmost pivot is concentric with the rear axle.

As on the rest of Trek’s full-sussers, the ‘Full Floater’ shock mounting of the old Top Fuel is gone. Instead, the Fox DPS air-can mounts directly to the frame at one end and to a magnesium rocker link at the other. Travel has been extended by 15mm for 2020.

In terms of geometry, the Top Fuel is now longer and slacker. Depending on which way you position the Mino Link flip-chip, the head angle can be set at either 67.5 or 68 degrees and the reach varied by 5mm, from 470 to 475mm on the large.

The effective seat-tube angle has been steepened to 75/75.5 degrees. With six sizes, it should be easy to achieve a perfect fit. The details of the frame have been well considered too, from its sleek, flowing lines to the fully-internal cable routing and integrated rubber protection finish.

Plus, Trek’s Knock Block steering-lock stops the fork crown fouling on the down tube.

Trek Top Fuel 9.8

Trek Top Fuel 9.8 kit

That 115mm-travel, air-sprung rear end is matched to a 120mm Fox 34 Performance fork. A bar-mounted RockShox TwistLoc remote lets you lock out both ends simultaneously, providing a firm pedal platform that’s easy to toggle on or off.

Combine that with a Bontrager Line Elite dropper post, and the Top Fuel switches easily into downhill mode, although a 10mm-shorter stem and slightly wider bar would help the handling.

Shimano’s SLX brakes are good, but it doesn’t take much to find the limits of the 160mm rear rotor and the lever return was a little sluggish.

I found the Bontrager XR3 tyres slightly flimsy too. They’re efficient uphill but the low-profile tread isn’t great on unsurfaced trails and I sliced a hole in the thin casing on a fairly mellow descent.

The bike’s price tag isn’t insignificant either and, while the spec is solid, I’d happily lose the carbon wheelset and bar to save some money.

Trek Top Fuel 9.8 ride impressions

You have to bite your tongue before criticising a bike like this because by its versatile nature it’s never going to be the best of the best in any scenario. With this in mind, there’s very little to fault in the way the Top Fuel rides.

With a poised feeling on the pedals even in the lower/slacker setting, the bike blasts up hills with minimal effort and I rarely found I needed to use the lockout apart from on long fireroads.

As a trail bike, the Top Fuel puts on an impressive show and never faltered, even when hammered into turns or launched off drops. The suspension gives you a solid base to push into and I was surprised after the first ride to discover that it only has 115mm of travel.

The main limiting factor to this downhill prowess is the low front end. When things get steeper, you do notice you’re on a bike that’s also built for going fast up hills. The short head tube and low stack height are clear indicators of this, and while for general trail riding I found them a little low, this does allow the bar to be fully slammed for all-out XC attacks.

Even with the 13-degree-rise stem positioned as high as possible on the steerer, I wouldn’t have minded a little more height. But then, upping the fork travel would blur the lines between the Top Fuel and the longer-travel Fuel EX.

On a bike like this, there are always going to be trade-offs, and opinion is always going to be biased by riding style, but for rapid mile-munching that doesn’t get in the way of enjoyment on the descents, the Top Fuel is hard to beat.

Trek Top Fuel 8 review

Once a lean XC race-focused machine, now a bulked up down-country rig. We test Trek's latest take on its short travel full suspension design.

Trek Top Fuel 8

Trek Top Fuel 8 Credit: Roo Fowler

Product Overview

Overall rating:, trek top fuel 8.

  • • Poppy, playful and efficient
  • • Available in six frame sizes
  • • Internal down tube storage
  • • Mino Link flip chip allows geometry tweaks
  • • Needs a 180mm rear rotor
  • • Accurate rear shock set up is crucial
  • • A solid build, so not the lightest in its class

Manufacturer:

Price as reviewed:.

Think Top Fuel, and the image of a XC race bike instantly springs to mind. But like a faded polaroid tucked into the corner for a dusty picture frame, it’s not an accurate representation of the current design. With the Fuel EX increasing in travel, the Top Fuel has been swept along in its backdraft and seen in high definition, it’s now a capable 29er trail bike with modern sizing and 120mm travel and one of the best down-country bikes on sale. 

Trek Top Fuel 8

A dropper post and sorted cockpit complement the Top Fuel’s playful and poppy nature

Trek offers the new Top Fuel in carbon and alloy options, where the Top Fuel 8 tested here is the high-end alloy build. Regardless of frame material all Top Fuels come with integrated downtube storage. And while the quick release hatch under the bottle cage isn’t big enough to cram a three course lunch into the frame, there’s enough space for a tube, multi-tool, a few snacks and a lightweight jacket. 

Trek Top Fuel 8

Down tube storage is handy for those riders who are travelling light

Trek always offers a comprehensive size range; and with frame options from S to XXL, with a tweener M/L option too, the Top Fuel 8 is no exception. It also has geometry adjustment, but rather than having Trek’s signature Mino Link on the seat stay pivot, the Top Fuel has a flip chip at the lower shock mount. In the low setting this gives a relatively tall 340mm BB height for a 120mm bike, which is probably the only carryover from its race-bike roots – designed to let you keep the cranks spinning, and the speed high at all times.

  • Best down-country mountain-bike: short travel full-suspension

The rest of the Top Fuel’s vital stats are on the money though, where a slack 65.6º head angle and steep 77.2º effective seat tube angle make it easy to hammer up the climbs and shred the descents. 

Trek Top Fuel 8

Flip chip in the lower shock mount offers 0.5deg head angle and 8mm BB height adjustment

It’s built solid too, the complete bike tipping the scales at 14.89kg. It also comes with a combined rider and bike weight limit of 136kg (300lb) so it’s clearly no wet noodle. Yes, it’s not the lightest for a 120mm bike, and not far off what you’d expect for a 150mm bike, but that’s the price you pay for integrated storage, as the alloy down tube needs reinforcing when you cut a hole in it.

Thankfully, the Top Fuel 8 rides light, as there’s less travel to pull through to get the bike off the ground, so it offers a different ride experience to modern long-travel trail bikes which tend to have one eye on enduro racing. 

Trek Top Fuel 8

The stock RockShox Pike Rush RC fork dishes out 130mm of travel

There are no sag gradients on the 130mm travel RockShox Pike fork, which we assume is down to cost saving, but set-up is still really straightforward with a tape measure to hand. And while the Pike has a reputation for having a sporty, firmer tune, the basic RC version on the Trek felt smooth and composed in all situations. Yes, the RC damper has a very wide range of rebound adjustment, but there’s only a small range that’s actually usable, but it is enough to get the rebound just so; and that’s all that really matters, right?

  • Best mountain bike suspension forks: XC, trail and enduro forks

You need to be equally attentive when setting up the rear suspension. Set to 30% sag, the top-end RockShox Deluxe Ultimate RCT shock bottoms relatively easily. So if you want to run the shock softer to achieve a lower dynamic BB height, you’re going to need to add volume spacers. As such, we increased the shock pressure and reduced the sag to 27.5%.

This small change alone was enough to prevent premature bottom out, but we could still use all of the available shock stroke when we really needed it. We also ran the low-speed compression setting in the minus position for maximum plushness. In the low geometry setting we measured rear wheel travel at 115mm, which is 5mm less than claimed. 

One of the biggest differences in terms of ride feel between the Lapierre and the Trek, other than sizing, are the wheels. The Bontrager Line 30 rims have a 30mm internal rim width, 5mm more than the Mavic rims on the Lapierre XRM 6.9 we tested the Trek against. This adds to the overall volume of the tyres and the stiffness of the bike. It is also why we dropped the tyre pressures slightly on the Trek, even though we were running the exact same tyres on both bikes.

Bolted on chainstay protection is a neat and considered touch

With 108 points of engagement the freehub on the Bontrager rear wheel offers rapid, secure engagement, with less chain slack and chain slap as a result. The bike is not totally silent though as there is a little bit of cable rattle, but it will probably disappear when you stuff the BITS storage box to the gills.

The contact points on the Top Fuel 8 are all sorted and while there’s a stack of stem height adjustment, the three 20mm spacers don’t offer any fine tuning of the handlebar height. So swapping one of the 20mm spacers of a 10mm, a 5mm and two 2.5mm spacers, would be our first move before leaving the store.

  • How to: ultimate guide to handlebar cockpit set up

Nothing else needs changing though. The mix of Shimano XT and SLX for the 12-speed drivetrain worked flawlessly in the dry, dusty test conditions, where the smaller 30t chainring is a real saviour on long draggy climbs or on days when your legs feel like lead.

Performance

The steep seat tube angle on the Trek Top Fuel 8 really helps with the pedalling dynamics on steeper climbs and the cockpit is long enough that even with the shorter 45mm stem, you never feel cramped or uncomfortable when climbing. It’s not so steep though, that it feels like the pedals are behind you when sitting down spinning across flatter, rolling singletrack.

Stand up to sprint and the rear suspension on the Trek clearly gets animated, the rocker link flapping around like the tail on an overly excited puppy. So the best approach is to sit and spin up the climbs, as the shock remains remarkably still and lifeless until you encounter a bump. Also if you really want to go for it on smoother climbs, the rear shock has a firmer pedal threshold setting. In short then, gaining elevation on the Top Fuel 8 is relatively straightforward and painless.

Knock Block 2.0 steering lock with 72º steering angle, protects the frame without limiting steering

So, it’s somewhat surprising just how rapidly you can throw those gains away. This bike simply rips the descents. Given the limited travel it still seems to carry speed everywhere, and while bumps that would normally chip away at your momentum are still felt though the chassis, they do not perturb the Trek one bit. It rails corners too. Simply load up the suspension mid-turn, and the Top Fuel has just the right amount of support and extension to keep the front end loaded, before slingshotting you out of the turn faster than you entered it. Combine the raw speed with the balanced weight distribution, and the Top Fuel 8 is a really fun, exciting ride and blisteringly fast too.

Would the Trek Top Fuel 8 be even faster with a genuinely low geometry setting? You bet it would. But we’d settle for a bigger rotor on the SRAM DB8 rear brake, as this bike is so fast in fact, that the 160mm rotor feels wholly inadequate and it looked like it had been tempered after just a couple of rides.

Trek Top Fuel 8

The Top Fuel 8 is at home on fast sweeping singletrack

At 14.89kg (32.83lb), the Trek Top Fuel 8 isn’t that much lighter than a 150mm bike. So if you want one bike to conquer all trails, it wouldn’t be our first choice. It’s still a great 29er trail bike though, and if bike park laps and enduro racing don’t fall under your trail bike remit, the Trek Top Fuel 8 offers a fast, fun and engaging ride. Its poppy playful nature, combined with generous sizing means you never feel limited by the travel for regular trail riding. Yet, it still feels more energetic and efficient under pedalling than than most 150mm bikes. It’s a heady combination that manages to keep both the tempo and fun factor high, without any apparent lows.

Trek top fuel curated reviews, 2023 trek top fuel 9.8 review - a tpc rider's quick take.

  • Versatile Performance
  • The Top Fuel 9.8 is a true chameleon on the trails. The bike's geometry and suspension travel, combined with the efficient RockShox Super Deluxe Ultimate, let you breeze through long cross-country trails and tackle technical descents with similar finesse.
  • Lightweight Yet Robust
  • The OCLV Mountain Carbon frame offers the best of both worlds. It's impressively lightweight for those steep, lung-busting climbs yet robust enough to handle rough descents without a hiccup.
  • Smart Wheel Sizing
  • Trek's smart wheel sizing (29" for larger sizes and 27.5" for smaller ones) ensures that riders of all sizes get the optimum fit and handling characteristics. XS frames receive 27.5" wheels, while sizes small and up get the 29er experience. 
  • The Top Fuel 9.8, with its advanced features and high-quality components, comes at a significant cost. ($8,699 base) While the performance justifies the price, it might still be out of reach for some riders.
  • May Not Be 'Enduro' Enough
  • While it's a capable descender, it might not be enough bike for riders who regularly ride steep and challenging enduro-style trails. The 130/120mm travel is perfect for most trails but may not offer the plushness desired for more aggressive, sustained downhill runs.

TVEL to introduce new fuel design at Dukovany

TVEL, the Russian nuclear fuel manufacturer, has signed contract with Czech utility ČEZ to introduce the RK 3+ modification of its VVER-440 fuel for the Dukovany nuclear power plant. Announcing the agreement today, TVEL said the new fuel will undergo a number of pre-irradiation tests aimed at qualification for a licence from the Czech Republic’s State Office for Nuclear Safety.

The project will take into account the operating experience of the prototype of such fuel at unit 4 of the Kola nuclear power plant in the Murmansk region of Russia’s Kola peninsula, where it has been in use since 2010.

The RK 3+ design has enhanced physical and thermo-hydraulic properties compared with previous generations of VVER-440 fuel, TVEL said, and has a longer fuel rod pitch that streamlines the water-uranium ratio in the reactor core and increases the efficiency of the fuel.

"The new project of switching Dukovany NPP to RK 3+ fuel will facilitate the optimisation of the plant's  fuel cycle strategy [and] increase the safety and economic efficiency of the power units’ operation," said Alexander Ugryumov, vice-president for Research and Development at TVEL.

The 2040-megawatt Dukovany plant has four VVER-440 reactors which were commissioned in succession between 1985 and 1987. It generates about 13 terawatt hours of power annually, providing about 20% of the country's electricity demand, TVEL said. The Dukovany and Temelín nuclear power plants produce about 35% of the national electricity output, making the Czech Republic one of the world' top ten countries in terms of the share of nuclear in its energy mix, it added. Temelín comprises two VVER-1000 units.

Both plants have been operated with fuel manufactured by TVEL’s Machine-Building Plant, in Elektrostal, Moscow region, since their commissioning.

In April, ČEZ announced the start of loading test fuel assemblies supplied by Westinghouse Electric Sweden into unit 1 of its Temelín plant as part of its plan announced in August last year to diversify its fuel supply. ČEZ said the move was to verify the properties of the fuel and to obtain know-how, and did not represent a switch to Westinghouse fuel.

The six fuel assemblies from Westinghouse Electric Sweden will work alongside those from TVEL. Last year, the power plant introduced 48 upgraded TVEL fuel assemblies to unit 2 "to complement the original fuel type", ČEZ said.

    The 2019 Trek Top Fuel 8 is an Cross Country Aluminium / Alloy mountain bike. It sports 29" and 27.5" wheels and has RockShox suspension. The bike is part of Trek 's Top-Fuel range of mountain bikes. Top Fuel 8 is a high-performance, high-value full suspension cross country mountain bike.

  2. Top Fuel

    Top Fuel is a quick short-travel 29er trail bike that's perfect for riders who like to stay pinned both up and down the trail. It's lighter and snappier than a trail bike, but it's a lot more forgiving on rowdy descents than a true cross-country bike. It's the best of both worlds, and a hell of a lot of fun in the dirt.
