Trek Top Fuel 8 review: a progressive rather than podiuming XC machine

Trek’s top fuel delivers superlative short-travel suspension performance but it’s definitely a trail bike not an xc bike.

Trek Top Fuel 8 review

BikePerfect Verdict

Awesome suspension, agile swagger, grippy kit and practical frame updates build a brilliant rally bike, but high weight buries any XC aspirations

Infectiously agile and playful vibe

Superlative suspension feel

Seriously tight tracking frame

Trail tough kit

Internal storage

Too heavy for XC racing

Simple fork damper

Tight internal storage access

Yawning gap between this and the Supercaliber

Top Fuel used to be Trek’s out-and-out best full-suspension mountain bike for racing, but with the soft-tail Supercaliber under its sponsored riders now, the Top Fuel has developed a burly rather than race character. 

The latest frame, suspension and spec changes to the 8 make the most of its short-travel agility and gripped tenacity to create a proper rally racer. Excess weight shows on climbs and acceleration though.

Design and geometry

The alloy Top Fuel frame not only has the same geometry, shock and suspension layout as its carbon counterpart but Trek’s engineers have also worked super-hard to give it the same extensive, updated feature lineup. That includes the lever-locked trapdoor into the down tube for internal storage, threaded bottom bracket shell with chain guide tabs. The Knock Block 2.0 inset now allows 72-degrees of steering lock (not 58-degrees as before) or you can fit a blank insert for full rotation if the bars aren’t slammed. 

In fact, it’s one of those bikes where we continually found ourselves riding how we always want to ride, not how we actually ride. That inevitably builds into an addictive upward spiral of confidence and insolent speed that often ended with us snapping at the heels of more expensive longer travel bikes even on really rowdy trails. Picking a larger, longer frame will settle it even more at speed, but for flow trails, it was refreshing to really rip those big Bontrager side tire lugs round on a compact, close combat chassis. Just be careful you don’t get too carried away, as however good it feels, less travel inevitably means the tires are having to cope with more impact force and we soon put a couple of splits in the rear tire despite the ‘inner strength’ casing.

When that happens the narrow neck of the storage hatch can make getting your spare tube out awkward and the high cage position means you won’t get a large bottle in either. There’s space for a 2.5in tire in the rear swingarm which pivots co-axially around the rear axle according to Trek’s ‘Active Braking Pivot’ wisdom. While it limits choice, the switch to a 34.9mm seatpost size should mean stiffer, smoother dropper action, especially on larger frame sizes which get up to a 200mm shaft stock. The new trunnion style shock pivots more smoothly and is the right way up now compared to last year’s inverted shocks. That means the MinoLink geometry flip chip to change angles by 0.5-degrees is now at the base of the shock but it’s still easy to get too. Significantly all RockShox spec Trek bikes from the 8 upwards get the same ‘Ultimate RCT’ spec Deluxe rear shock.

The alloy frame is a kilo heavier (3.74kg vs 2.7kg) than the carbon option according to Trek’s weights. This saves you $1,400/£1,500 if you buy the frame separately, although it still retails for $2,319.99/£2,350. Those numbers prove it’s neither affordable or light for a bike that you’ll find listed in the XC section of Trek's website, not the trail pages. In fact, the 130mm Fuel EX Al frame is the same weight although that doesn't have internal storage.

A 66/66.4-degree head tube definitely suggests progressive riding rather than traditional podium hunting vibes too. The 465/469mm reach on our M/L size is more trad than rad though so riders after a stretch should make use of the short 450mm seat tube and opt for the L with a 480/484 reach. All bikes get the same 76/76.4-degree seat tube angle and 434/435mm chainstay length though so while having six (S-XXL) sizes is great, the balance is definitely centered around the M - M/L - L models.

Components and build 

The Top Fuel 8 is the most expensive alloy bike, above the 7 at $3,529.99/£3,200 and the 5 at $2,629.99/£2,700 (we don’t know what 6 did to offend them but its missing from the line-up), but below the carbon-framed 9.7 at $4,229.99/£4,700.

The highlights of the package are the lightweight SID fork (albeit with the simplest Rush Damper) and Shimano XT rear mech and shifters. The Bontrager XR4 tires are some of our favorite welterweight all-rounders too. The SLX crank is a great piece with a 30T ring for easy climbing, but muscle Mary’s will find a 36T fits the frame too. You get a 150mm Trans-X dropper with a Bontrager Arvada saddle on top and 35mm diameter Bontrager Elite 45mm stem and 780mm wide bar.

Deore four-pot brakes just about do the job adequately via 180/160mm rotors but together with the wide rim tubeless Bontrager Line Comp 30 wheels they’re an obvious area where extra weight creeps in and adds up to nearly 14.5kg without pedals. 

Performance

Add that weight to chunky treaded, relatively grippy tires and however Trek categorizes the Top Fuel, the 8 clearly isn’t the best choice for charging climbs and ripping round simple XC laps. Now we’ve got rid of the people who’ll likely love the 12.2kg Trek Supercaliber for the same money, we can start talking about what the Top Fuel does do really well – and that’s riding properly rowdy.

While bikes like the Evil Following , Santa Cruz Tallboy , and Norco Optic have already established that short-travel bikes can feel awesome, the Top Fuel definitely goes into the small travel, BIG capability hall of fame. Like most of its peers, it doesn’t squander initial shock movement and can feel slightly sharp in the car park unless you drop tire pressures low. 

Once moving though it’s both amazingly fluid and connected over ruts and roots whether climbing janky tech or sucking onto stutter bump/root ripple turns or off-camber high lines. The wheel path and rear pivot position mean there’s minimal pull back through the pedals as it hoovers up chunder so you can stay on the gas without getting jacked or stalled out. While we’re always suspicious of acronyms and a 160mm rotor doesn’t generate much torque anyway, the braking performance of the ABP rear end is impressively grippy compared to the same hardware on other bikes. 

The RCT damper also has plus and minus low-speed compression settings to fine-tune support sensitivity depending on personal/terrain preferences. Even in the plus setting the mid-stroke mobility does mean you’ll want to flick into the much firmer ‘pedal’ mode if you’re stood up slow cadence churning on a climb or don’t want distracting bounce on long smooth climbs. The SID fork gets a similar firming option via the fork top lever though we rarely touched it unless we were really hanging on a road climb.

While the superlative suspension performance is definitely the heart of the Top Fuel’s ‘have a go hero’ character, the rest of the bike definitely exploits it rather than squandering it. The alloy frame might be heavy but it’s seriously stout when it comes to squaring up to the trail when things get punchy.

While the simpler Rush damper starts to get seasick and inconsistent well before the back end, the 35mm stanchions do a great job of staying on track. Shorter travel means less dive too and together with well-balanced cockpit dimensions and steering angle gives a really predictable and tenacious target lock.

Despite the hefty weight and relatively slow rear hub engagement the fact you can keep the power down or brake really late meant the Top Fuel always felt hyped to be hitting trails and tweaking lines as fast as possible. The shorter M/L size made it a proper joyride on tighter, twistier trails but you can still drive it really hard, heels down, feet level through turns and it loves to pump downslopes.

Trek’s Top Fuel 8 is a brilliant example of just how good short-travel suspension can feel, and less stroke always means a more responsive, visceral ride than a leggier bike. The geometry and proper trail tires really let you exploit the hooligan that’s hiding in the frame along with your pump, tool and spare tube too. 

As much as we’ve loved ripping around the trails on it, there’s no doubt it’s heavier and harder to accelerate/elevate than we’d like for its supposed XC/downcountry range placement though. If you’re about the overall vibe, not outright velocity, that doesn’t matter though.

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

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. 

Trek Top Fuel 8

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. 

Trek Top Fuel 8

ABP suspension design transforms the seat stay assembly into a floating brake mount

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.

Trek Top Fuel 8

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. 

  • Best cross-country XC mountain bikes: hardtail and full suspension

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.

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."

MBUK’s Trail Bike of the Year 2022

“It’s easy to look at the bike from afar and assume this is just another downcountry rig... It wasn’t until I’d fired it over some jumps, nosed it down the odd steep chute and slung it through my test loops’ berms that I realised the Top Fuel is, simply put, a bloody brilliant trail bike.”

"Enduro’s Best Downcountry Bike of 2022"

"Top Fuel 9.9 XX1 AXS earned top honors in Enduro’s round-up of best downcountry rippers, thanks to the bike’s clean look, practical details, and progressive suspension."

No image available

"This is a really, really good bike"

"The Top Fuel is a very capable descender, but its well-proportioned geometry is just half the story. It manages to strike a great balance between grip, tracking, and precision. The whole bike seems to just will you on to hit things faster and with more precision."

No image available

"This thing rips"

"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."

  4. Trek Top Fuel 8 review: a progressive rather than podiuming XC machine

    Trek's Top Fuel 8 is a brilliant example of just how good short-travel suspension can feel, and less stroke always means a more responsive, visceral ride than a leggier bike. The geometry and proper trail tires really let you exploit the hooligan that's hiding in the frame along with your pump, tool and spare tube too. ...
