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.

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

Why trust BikePerfect Our cycling experts have decades of testing experience. We'll always share our unbiased opinions on bikes and gear. Find out more about how we test.

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.

2020 Trek Top Fuel 8 fork upgrade

• Add to quote

Hello. Neubee here. What's is the most fork travel/upgrade that I can put on 2020 Trek Top Fuel 8 XL going from Rockshock silver 120mm that is a stock fork. I regularly bottom out although pressure is by spec and there is nothing wrong with it otherwise. I am 250lbs and was told any increase in travel will change geometry significantly and put a lot of pressure on steer tube causing it to crack. Some places are mentioning it is safe to go 140mm...no idea, Trek website has no documentation on it. I appreciate any insights.  

The plastic Motion Control damper in your fork has very poor performance capability. No small bump compliance and is overwhelmed when the speed goes up. You can't upgrade the damper. A working fork at 130 would be a major improvement. A used Pike with a Charger2 damper or a Marzocchi Bomber Z2 or DVO Diamond would change things.  

Trek listed 130mm for max fork travel on the 2020-2021 model Top Fuels. Sent from my iPhone using Tapatalk  

That 130mm figure is in the FAQ here if you want to check. Scroll down to the Bike tech section. Top Fuel 9.8 | Trek Bikes (NZ)  

Thank you all for the help!  

I would also look into air tokens (they will help with the issue of bottoming out )  

Bottoming out isn't a priority problem when the damper stops allowing the stanchions to respond to bumps when your speed gets up on a steep downhill. You trash the fork. Get rid of it. Today, since May, you can spend 550 or less on a Manitou Mattoc Comp with an ABS+ shim stack damper like you get on motocross forks. Change the shims to make it handle anything you want to ride. Travel internally adjustable 110-160.  

So true. Correct info can work fr anybody clicking on it now.

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/

- 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:

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.

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 .

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.

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.

Trek Top Fuel price & specs

We’ll see four Trek Top Fuel models coming into Australia this year – two with alloy frames and two with carbon. All Top Fuel models feature the same geometry, suspension design and travel. They’re all equipped with 29in wheels, and there are five frame sizes available from Small through to X-Large (the XS size with 27.5in wheels won’t be available in Australia).

Pricing kicks off at $3,499 AUD for the Top Fuel 5 and goes up to $8,299 AUD for the Top Fuel 9.8 XT that we have on test here. Additionally, Trek will offer a 9.9 spec via the Project One bike builder program.

You can check out the specs and prices for all those models down at the bottom of the page. Right now we’ll be diving straight into our experience of testing this bike here; the Top Fuel 9.8 XT.

• Frame | OCLV Mountain Carbon Fibre, ABP Suspension Design, 120mm Travel
• Fork | RockShox SID Select+, Charger 2 RL Damper, 44mm Offset, 120mm Travel
• Shock | RockShox Deluxe Ultimate RCT, 185x50mm
• Wheels | Bontrager Line Elite 30, OCLV Carbon Rims, 29mm Inner Width
• Tyres | Bontrager XR4 Team Issue 2.4in Front & Rear
• Drivetrain | Shimano XT 1×12 w/XT 30T Crankset & 10-51T Cassette
• Brakes | Shimano XT 4-Piston w/Ice Tech Rotors
• Bar | Bontrager Line Pro, OCLV Carbon, 27.5mm Rise, Width: 750mm (S), 780mm (M-XL)
• Stem | Bontrager Line Pro, 45mm Length
• Seatpost | Bontrager Line Elite Dropper, 34.9mm Diameter, Travel: 100mm (S), 150mm (M-M/L), 170mm (L), 200mm (XL)
• Saddle | Bontrager Arvada, Austentite Rails
• Confirmed Weight | 12.88kg (Large, Tubeless)
• RRP | $8,299 AUD

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.

Trek Top Fuel 8 2022 Review

The Trek Top Fuel 8 was launched in the fall of 2021. It features a 120mm front and rear suspension, more modern geometry, and internal frame storage over the previous generations. The Top Fuel used to be the flagship cross-country bike but that has since been replaced by the Supercaliber. On one hand, it feels like Trek just keeps making the same bike but renaming it. The Fuel EX used to be a short travel trail bike, the Slash was once a 27.5 mid-travel, and so on. Now everything has moved up and gotten longer, lower, and slacker over the last 6 years as you would expect.

The Trek Top Fuel 8 is a full aluminum frame sporting BONTRAGER wheels, bar, stem, tires, and dropper seat post. Paired with a Shimano XT/SLX group set and Rock Shox suspension package to finish it off. This build comes with top of a line rear shock the Delux Ultimate. With great tuning abilities and a lockout, it suits a wide variety of riders. On the front end, it’s paired with a SID select. While offering 120mm of travel and 35mm sanctions being the highlight. This fork paired with the nice rear shock is a bit of a letdown. I’d rather see a step down in the rear and a high-end fork with a few more adjustments. The new 2023 spec offers a Pike at 130mm of travel if you’re looking at that model. 

With reliable shifting from Shimano its hard to go wrong here. Coming back to my main weak point with most entry level Trek bikes its the wheels. While offering great engagement in the hubs the alloy wheels are just so soft they ding and dent so easily. As well this bike came equipped with the SRAM DB8 brakes. While they look good I wasn’t impressed. Out of the box they needed a bleed. Well its not DOT fluid, it uses Mineral oil. Thus requiring a different bleed adapter and oil. Which I didn’t have so I changed the really quick. More on that later.

Ride Quality

After a few months of lugging this bike around the country and riding different trails, it’s safe to say that it’s very efficient in all areas of climbing and defending. While a bit undergunned for steep technical riding it’s still capable if you choose the right line and control the speed. Drops and jumps are just fine with a short travel bike but sticking to the more mellow ones is something I would recommend. 

This Top Fuel is the first bike in almost 2 years that’s a full 29er, I’ve been rocking that  mullet  life for a bit now. I can notice the extra speed the rear end carries when climbing for sure. It acts like it just goes up and over everything so well. Now with the efficiency of the short travel paired with the 29 wheels, it’s a no-brainer that it’s great in this category. At the current setup of this bike it’s coming in at 32.2 lbs with pedals, and a tube in the frame. (Down tube storage for the win) Not the Lightest bike but it doesn’t feel heavy on steep climbs. 

Changes and Upgrades

Out of the box I had issues with the SRAM DB8 brakes so those went straight to the trash. Back to the shop at least for a trade-in credit. Swapping them out for G2 RSC, but keeping the stock centerline rotors for now 180F 160R. Later I upgraded to HS2 180 F&R for better power, traction control, and less braking fatigue on a long descent. I also wanted to keep the line of SRAM brakes through all my  bikes  so my bleed kit, changing of rotors, and things are easy. The second upgrade I did right out of the box was the wheels. Swapping them out for some Hope Fortus 30 SC with Pro 4 hubs. While this swap didn’t get me any weight savings it did give me a better alloy rim paired with some pretty good hubs. 

After about 6 months of riding this setup, I was finding I wanted this bike to pack a punch and handle the rough stuff more confidently. I happened to have a Pike Ultimate 140mm lying around and I swapped that on there. Instantly the bike was changed. It felt like a mini Fuel EX, which it is anyway. Taking the head tube angle to almost 65 degrees from the stock 66 helps keep that bike stable at speed as well. with no extra weight added in this move, the bike still feels like a climbing machine. 

Now you may be looking at this and asking why didn’t I just buy the nicer build. Well, I didn’t want to spend that much up front. With the wheel and brake swap on day one I only spent a few extra hundred dollars. Knowing I had that Pike to try out at some point as well it sounded like the best deal. 

This bike I am riding is a M/L frame and I find it sweet that Trek offers that middle size for folks in-between. More sizes the better for everyone. Stock specs can be found  here

The Top Fuel 8 retails at $3,999 (shops may have 2022s on sale for $3,499 or less) The next build in the lineup is the 9.7, coming with a carbon frame and almost identical part package. Retailing at $4,699. with the changes I made that’s pushing that bike to almost 5k and without much weight swings so I opted to save a few bucks and try something different. Trek offers a wide range of builds from $2,699-$10,999.

Who’s this bike best for? I think a lot of cross-country to trail riders would enjoy this bike, it’s got the speed for racing but a sporty feel for everyday trail riding. Some people like the word “down country” and while it’s a great way to describe this bike, I feel like it’s an over used term in the industry. 

Pros and Cons

• Pedal efficent
• Ultimate level rear shock
• Frame storage
• Shimano groupset
• capable and efficient climber
• Bontrager Line Comp 30 Wheels
• Knock Block (can remove but its just annoying)
• Basic SID fork
• 34.9 mm dropper post. hard to find replacement at this time.

New 80 MPH military electric bicycle unveiled as e-bike maker opens defense division

Los Angeles-based electric bike brand Hi-Power Cycles has announced the opening of a new “defense division” known as HPC Defense. To kick things off, they’ve unveiled an 80 mph (130 km/h) military electric bike as one of the division’s first products.

Theoretically speaking, electric bicycles in the US are limited to a maximum speed of 28 mph (45 km/h). But that’s just the civilian limit. If you’ve got the clearance to buy HPC Defense’s new Revolution W electric bike , you’ll be capable of exceeding that speed several times over.

The Revolution W is said to be fully manufactured in the US and sports some serious power, which the company says makes it the “fastest factory military-grade e-bike in the world.”

A 10,500-watt motor can send the bike flying at speeds of up to 80 mph (130 km/h). And if you’re wondering if the bike pedals well at such high speeds, you may be surprised at the answer.

“Thanks to the German-made Schlumpf High-Speed Drive, you are able to achieve pedal speeds over 50 mph,” explained the company. “With a click of your heel, you can enable the 2.5x overdrive feature and maximize your efficiency at high speeds.”

The Revolution W claims a throttle-only range of up to 100 miles (160 km), though that’s almost certainly measured at a lower average speed.

And just like you’d expect of any overlanding-style electric bike, the Revolution W has extremely long range travel suspension. According to the company, the bike features 9″ of rear suspension travel and 8″ of travel in the front.

There’s no word on what the bike costs, though consider that it appears to be wearing an $1,800 to $2,000 fork , depending on the loadout, it’s likely the kind of lofty figure you’d expect to see on a DoD budget line item.

Along with the establishment of HPC Defense, the company also announced the onboarding of new Advisor & Interim President/CEO Bryan Maizlish.

As a public sector industry veteran, Maizlish formely held leadership positions within divisions at Lockheed Martin, Northrop Grumman/TASC, Jacobs Engineering (Jacobs), and Human Security (HUMAN), a Goldman Sachs portfolio company.

Military e-bikes are’t exactly new, and in fact are becoming more common than ever. The Russian invasion of Ukraine has propelled military e-bikes into the spotlight multiple times as Ukrainian defenders have creatively repurposed off-road electric bikes for transporting anti-tank missle teams as well as inserting sniper teams .

Even earlier, other militaries have long emplyed electric bicycles for patrol duties and tactical operations .

Top comment by Ajemo Haltom

From a financial standpoint, this makes a lot of sense. Just the soldier, their gear, and an ebike. I don't know much about military budgets, but this seems like the most efficient way to move troops (over land).

Compared to electric or combustion-powered dirt bikes, electric bicycles have the advantage of significantly lower weight and increased manueverability. And while it likely wouldn’t be very fast going, the pedals also serve as an alternative propulsion method if the bike ever runs out of fuel.

Electrek’s Take

I’m going to go out on a limb here and say that, being in the rare overlap between veterans and e-bike journalists, I’m one of the few people who has had the unique experience of riding an e-bike as part of my service. Outside of novel issues like trying to keep your flash suppressor out of the spokes, it’s hard to beat the advantages of e-bike mobility for a soldier.

The ability to manuever both quickly and quietly through rough terrain is something thing that bests both combustion-powered dirt bikes and good-old-fashioned humping it on foot. Anyone who has ever completed a 12-mile ruck march is probably drooling over a bike like this.

To be realstic, these types of extremely high speeds are unlikely to be used off-road though, at least not outside of long, relatively smooth and straight dirt roads. But these levels of power and torque are certainly useful for off-road terrain and mountainous areas with steep inclines, not to mention the extra weight usually carried by soldiers. And having the extra speed available certainly isn’t a bad thing, as you never know when you’re going to need to leave in a hurry.

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."

"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."

"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."
