Trek Fuel EX Vs Top Fuel Mountain Bike ?

Trek mountain bikes are built for the trails, and no bikes illustrate that better than the Trek Fuel EX and Trek Top Fuel. So, it’s understandable to pit Trek Fuel EX vs Top Fuel, which compels us to ask, what’s the difference?

Trek Fuel EX is a full suspension 29er trail bike with a 140mm front suspension and a 130mm rear suspension, while Trek Top Fuel is a 29er or 27.5-inch full-suspension cross-country bike with a 120mm front and rear suspension.

So, you can distinguish the trail bikes according to the type, suspension travel, and wheel size. Other differences are with respect to the geometry, suspension technology, project one customization, speed, weight, and even price.

Below is a table breakdown of all the nine differences between Fuel EX and Top Fuel to be explored in detail later:

This article will not just discuss the differences between the two Trek MTBs but will also highlight their similarities. Without saying much, let’s begin with the bikes’ overview.

Trek Fuel EX Overview

Trek Fuel EX is a full suspension trail mountain bike by Trek designed to take on just about any trail all season long.

This mountain bike comes with a balanced trail geometry that brings out the perfect balance between speed and control. As a result, it’s easier to handle on tricky trails and promises a fast pace.   

Fuel EX is available in 29-inch (29er) and 27.5-inch wheel sizes to accommodate all heights. Women who naturally have a shorter stature can set for 27.5-inch options, while men who are inherently taller can go for 29ers.

Suspension-wise, Fuel EX features a 140mm front suspension and a 130mm rear suspension, which is enough to hit just about any trail and enjoy the same comfort and bump-cushioning.

In terms of suspension technologies, the manufacturer employs Mono Link to self-adjust the bike frame, Re: Aktiv to offer you more control, and Active Braking Pivot for more confident braking.   

The most notable miss is the Project One customization option. But we’ve several models to choose from, such as Fuel EX 5 Deore, Fuel EX 9.1XOR, Fuel EX7, Fuel EX 8, Fuel EX9.7, Fuel EX 9.8 GX/XT/GX AXS, Fuel EX9.9 XTR, and Fuel EX 9.9X01 AXS.

Overall, Trek Fuel EX is perfect for anyone who wants a versatile do-it-all mountain bike.

Trek Top Fuel Overview

Trek Top Fuel is a short travel 29er cross country mountain bike designed for cross country racing and fun trail riding.

This bike is more forgiving and impulsive on aggressive descents than regular XC bikes but has a snappier feel than a traditional trail bike. So, it gives you the best sense of both worlds.

It has a 120mm front suspension and 120mm rear suspension to have a more comfortable and confident ride. And since it’s a 29er, obstacle rolling is much funnier. The full-suspension XC bike enjoys a progressive geometry, which is more relaxed and offers you more control.

Suspension-wise, this XC bike employs Mono Link Technology and ABP, just like Fuel EX to promise self-adjustment geometry and confident braking.

But unlike Fuel EX, Top Fuel lacks Re: Aktiv suspension technology. Instead, it employs Anti-Squad technology, a suspension resistance technology that offers you more acceleration with every pedaling. That’s practically why this bike is a better cross-country racing bike.

The best bit is that Top Fuel is customizable through Project One. But still, the bike family is split into several models – which include Top Fuel 5 Deore, Top Fuel 7 Deore/XT, Top Fuel 9.7 SLX/XT, Top Fuel 8, Top Fuel 9.8 GX/AX SXS/XT, and Top Fuel 9.9X01/XTR/XX1 AXS.

Trek Fuel EX Vs Top Fuel Side-By-Side Comparison!

Now, here is how Fuel EX and Top Fuel compare:

1. Bike Type

Fuel EX is generally a trail mountain bike that can take on just about any trail every day – from dirt trails to rough off-roads and forest trails.

On the other hand, Top Fuel is a cross-country mountain bike that you can use for any cross-country event. Whether you want to compete at a local event or race casually in the countryside, you cannot go wrong with Top Fuel.

2. Suspension Travel

Fuel EX is a do-it-all mountain bike mainly because of its long travel range. The bike features 140mmm of front suspension and 130mm of rear suspension, enough to take on all terrains.

The suspension allows you to ride downslope and go over rocks. That’s how powerful the MTB is. Top Fuel promises 120mm suspension travel on the front and rear side, shorter than what you get from Fuel EX but enough for cross-country biking.

You want your cross-country race bike to feel lightweight and offer you better control, and that’s what you get from the 120mm travel range.

3. Trek Fuel EX Vs Trek Top Fuel Wheel Size

Top Fuel is a 29-er (29-inch mountain bike), while Fuel EX offers 29-inch and 27.5-inch wheel options. The difference is that 29ers mostly favor taller guys while 27.5-inch accommodate both taller and shorter guys.

So, you are more likely to get a matching fit with Fuel EX than Top Fuel. However, the advantage of Top Fuel is that you can have a custom-made bike matching your body size.

4. Geometry

These two Trek mountain bike families differ in their geometry, which affects their overall feel.

Fuel EX, for example, has a balanced trail geometry, which bridges the gap between the fast-handling short-trail geometry and the slow-handling greater-trail geometry.

As a result, the bike is easier to handle at high-speed and, pretty stable, and offers you more control. You cannot ask for anything better than a balanced trail geometry.

On the other hand, Top Fuel has a progressive geometry characterized by a longer wheelbase, thus more relaxed and promising more control.

5. Trek Top Fuel Vs Fuel EX Suspension Technology

Both Trek MTBs employ Active Braking Pivot (ABP) and Mono Link suspension technologies. ABP generally tunes the bike suspension to the braking and acceleration to enable you to brake more confidently and boss the trail.

Mono Link in opposite allows you to adjust the bike’s geometry quickly and on the go. The difference is that Fuel EX employs Re: Aktiv suspension technology while Top Fuel uses Anti-Squat suspension technology.

Re: Aktiv offers Fuel EX more grip, control, and a responsive feel, while Anti-Squat suspension allows you to go faster with every step. The more you pedal a Top Fuel, the faster it accelerates.

6. Trek Ex Vs Top Fuel Project One

Project One is Trek bike’s customization project. While Project One is available for top high-end Top Fuel models, it’s not available for Fuel EX. So, if you want a custom-made MTB for competition, Top Fuel is the way to go. 

That, however, doesn’t make Fuel EX an inferior family. No! There are so many high-end Fuel EX models to choose from, and they all come in all frame sizes, which means you can easily find your fit.

7. Bike Weight

There is at least a 2-4-pound difference between Fuel EX and Top Fuel of the same generation and size. For example, while Fuel EX 9.9 X01 AXS weighs 28.15 pounds, Top Fuel 9.9 XXL weighs 26.13 pounds.

That makes Top Fuel lighter than Fuel EX, and it’s understandable, given that Top Fuel is a cross-country racer while Fuel EX is a trail bike.

8. Top Speed

Being the lighter of the two and employing Anti-Squat technology makes Top Fuel faster than Fuel EX. That hugely explains why Top Fuel is a cross-country bike as it’s speedy, thus suitable got cross county.

Though you can race with a Fuel EX since it’s an all-terrain trail bike, you cannot go as fast as someone riding an XC bike, which is Top Fuel.

9. Bike Price

Trek Top Fuel costs more than Fuel EX because of the lower weight advantage, anti-squat technology, and Project One customization availability.

When it comes to choosing a mountain bike , there are many factors to consider. One important factor is the type of wheels you want. There are two main types of mountain bike wheels: 26-inch and 29-inch. Each has its own pros and cons.

26-inch wheels are the traditional mountain bike wheel size. They’re smaller and lighter than 29ers, which makes them easier to maneuver on tight trails. They’re also more affordable. However, they don’t roll over obstacles as easily as 29ers.

29-inch wheels are the newer standard for mountain bikes. They’re larger and heavier than 26ers, making them tougher to maneuver on tight trails. But their increased size helps them roll over obstacles more easily. They were also more expensive.

the Trek Fuel EX and Top Fuel are two of the most popular mountain bikes on the market. Both bikes offer great performance and features, but there are some key differences between them. One of those differences is in the wheels.

The Trek Fuel EX comes with 27.5″ wheels, while the Top Fuel has 29″ wheels. There are pros and cons to both wheel sizes, but it’s ultimately up to you to decide which one is best for your riding style.

If you’re looking for a bike that can tackle any terrain, the Trek Fuel EX is a great option. It’s extremely versatile and can handle everything from singletrack trails to technical downhill sections. The 27.5″ wheels offer good traction and rolling speed, making the Fuel EX a great all-around bike.

If you’re mostly riding on smooth trails or racing, the Top Fuel is a great choice. The 29″ wheels roll over obstacles much easier and provide a smoother ride. The downside is that the bike can feel sluggish on tighter trails, so if you like to mix up your riding, the Fuel EX might be a better option.

What Is The Difference Between Trek Top Fuel And Fuel EX?

The Trek Top Fuel and the Fuel EX models are both great choices for mountain biking. They both have their own unique set of features that make them stand out from the rest. Here is a quick comparison of the two models:

Trek Top Fuel:

– Carbon frame

– 29” wheels

– 120mm of travel

– Shimano XT/SLX drivetrain

– Weight: 28 lbs

– Aluminum frame

– 27.5” or 29” wheels (depending on the model)

– 140mm of travel

– SRAM GX/NX drivetrain

– Weight: 30 lbs (27.5” model), 31 lbs (29” model)

As you can see, the Top Fuel has a carbon frame which makes it lighter weight than the Fuel EX. It also has slightly less travel, but that is because it is designed as a cross-country race bike.

The Fuel EX is more of an all-around mountain bike that can be used for everything from racing to trail riding. It is available with either 27.5” or 29” wheels, so you can choose the size that best fits your riding style.

Both models come with Shimano or SRAM drivetrains, so you can choose the one that you are most comfortable with. The Top Fuel is also available in a women’s specific model.

Is The Trek Fuel EX An XC bike?

The Trek Fuel EX is a full-suspension mountain bike that is popular among cross-country (XC) riders. Some people may wonder if the Fuel EX is more suited for XC riding or if it can handle other types of mountain biking as well.

The truth is, the Fuel EX is an incredibly versatile bike that can perform well on a variety of terrain. While it may not be the absolute best choice for every type of mountain biking, it is certainly capable of handling most XC trails and even some more technical ones.

If you’re looking for a do-it-all mountain bike that can tackle just about anything, the Trek Fuel EX is definitely worth considering.

So, which bike is right for you? If you’re looking for a race-ready machine that can handle just about anything, the Top Fuel is definitely worth considering. However, if you’re more interested in an all-around trail bike that’s still incredibly capable, the Fuel EX is a great option. Ultimately, it comes down to your personal riding style and preferences.

Overview of the Trek Fuel EX

The Trek Fuel EX epitomizes the modern trail bike. As a full-suspension 29er, it’s designed to provide control and stability across various terrain and trails. This makes it an excellent choice for a daily rider or all-mountain enduro racing.

With 140mm of front suspension travel and 130mm in the rear, the Fuel EX soaks up bumps and obstacles whether you’re going uphill or downhill. This plush suspension lets you maintain momentum and power over even the most technical trails. Trek’s active suspension technologies, like the Re:aktiv shock, provide a smooth and responsive feel.

An aluminum or carbon frame paired with quality components like Shimano SLX, XT drivetrains, and Bontrager Line wheels give the Fuel EX durability and all-weather performance. The balanced trail geometry provides a middle ground between agility and high-speed stability.

One standout feature is the Fuel EX’s versatility. It has 29” and 27.5” wheel options to fit many riders. The frame sports a water bottle mount and is compatible with a front derailleur if you want to run a 2x drivetrain. Plus, there are multiple build specs at different price points.

Overall, the Trek Fuel EX lives up to its reputation as a confidence-inspiring trail bike ready to take on everything from mellow singletrack to the most gnarly downhill trails.

Overview of the Trek Top Fuel

Whereas the Fuel EX leans towards trail riding, the Top Fuel is Trek’s thoroughbred cross-country racing bike. It prioritizes speed, acceleration, and climbing ability above all else.

The Top Fuel lives up to its name with 120mm of suspension travel front and rear. This shorter travel paired with a carbon frame provides a lightweight and responsive feel on fast cross-country courses and flowy singletrack. The 120mm may be less than the Fuel EX, but it’s explicitly dialed to smooth roots and more minor hits at speed.

Trek only outfits the Top Fuel with 29” wheels, taking advantage of the larger diameter’s faster rolling and obstacle-clearing ability. The geometry is optimized for cross-country racing with a steep 74° headtube angle and a shortened wheelbase for quick steering.

High-end carbon frames keep complete bike weights under 23 pounds. The premium build specs feature Shimano XTR or SRAM XX1 Eagle drivetrains with 12-speed cassettes and race-ready carbon componentry. The suspension comes dialed from Fox Racing Shox or RockShox with lockout.

While not the best choice for technical downhill and enduro racing, Top Fuel’s cross-country prowess is hard to match. Trek engineers have created a World Cup-level XC rig to quickly shoot up climbs and rail berms. It’s built for riders who want every advantage when racing against the clock.

Here is a comparison chart highlighting the key differences between the Trek Fuel EX and Top Fuel mountain bikes:

Direct Comparison of Key Specifications

Now that we’ve provided an overview of each model let’s directly compare some of the key specs and components. This will reveal precisely where the Fuel EX and Top Fuel differ.

• Suspension Travel:  The Fuel EX has 140mm front and 130mm rear suspension, while the Top Fuel has 120mm front and rear. The Fuel EX has more travel and is better suited for rough trails.
•   Wheel Size:  The Fuel EX has 29” and 27.5” options. The Top Fuel is only available in 29”. The Fuel EX fits more riders.
•   Frame Material:  The Fuel EX has alloy or carbon frames, and the Top Fuel is carbon exclusively. The Top Fuel frame is lighter.
•   Geometry:  The Top Fuel has a steeper 74° head tube angle than the Fuel EX’s 67.8°. This makes it handle quicker at high speeds.
•   Drivetrain:  The Fuel EX is spiced with Shimano SLX/XT or SRAM GX. The Top Fuel gets higher-end XTR or XX1 Eagle drivetrains.
•   Brakes:  Both bikes come equipped with hydraulic disc brakes. The Top Fuel often gets higher-end Shimano XTR brakes.
•   Weight:  The Top Fuel size 19.5” can get under 23 pounds. The Fuel EX tends to weigh around 26-28 pounds.

As you can see, the Top Fuel edges out the Fuel EX regarding specs. But the Fuel EX is no slouch and offers tremendous versatility at a more accessible price point.

Riding Experience and Performance

Beyond just the specs, what matters most is how a bike rides out on the trail. This section compares how the Trek Fuel EX and Top Fuel perform when put to the test.

The Fuel EX is the more versatile of the two bikes. With its well-rounded geometry and quality suspension, it can comfortably handle various terrain. Flowy singletrack, steep descents, big jumps, and technical sections are manageable thanks to the balanced handling and plush 140/130mm of travel.

The Fuel EX also fares well in enduro racing, where uphill and downhill performances are equally important. The 27.5” wheels provide quick handling and acceleration on climbs while the long travel soaks up hardcore downhill runs. It’s also great for lift-served riding at bike parks.

Alternatively, the Top Fuel shines at high speeds over less technical terrain. Its stiff, lightweight carbon frame and fast-rolling 29” wheels let you fly up climbs and hold momentum over undulating singletrack. The 120mm of travel provides enough cushion for smoothing roots and more minor obstacles at a race pace.

While the Top Fuel can still handle intermediate trails, its limitations become more apparent on steep, loose descents than the Fuel EX. Quicker steering also requires more focus at high speeds. But for cross-country racers, it delivers every advantage possible when it counts.

Both bikes utilize quality components and advanced suspension designs to provide a precise, confidence-inspiring ride. However, the Top Fuel’s focus on weight and speed gives it the edge for racing, while the Fuel EX takes the lead for versatility.

Ideal Use Cases Given the differences in design and performance, the Trek Fuel EX and Top Fuel best suit slightly different riding applications.

The Fuel EX is the better choice for mountain bikers looking for a high-performance daily driver. It excels at everything from mellow singletrack to downhill riding while providing quality components at a reasonable price. The Fuel EX is also excellent for newer riders exploring different disciplines and trail types.

In comparison, the Top Fuel is ideal for competitive cross-country racers and riders who prioritize lightweight and absolute speed above all else. Its flyweight carbon frame and fast-rolling 29” wheels give it superior acceleration and handling at a race pace over less technical trails. The premium specs are worth it for racers chasing every advantage.

To summarize:

Fuel EX – Better value for the aggressive trail rider. More versatile for varied terrain. Casual trail riders looking to have fun on the descents while exercising good fitness on climbs are likely better served by the well-rounded Fuel EX at a more affordable price point. But hardcore cross-country racers should give the advantage to the Top Fuel.

Wil reviews the Trek Fuel EX 2023

Having undergone a ground-up redesign for 2023, the Trek Fuel EX has entered its burliest and biggest travel form yet. This latest model represents the 6th generation of Trek’s popular mid-travel trail bike, with the original having debuted all the way back in 2005. Trail riding has evolved a lot since then, and the new Fuel EX aims to keep up with that evolution by incorporating almost every mod-con you can think of.

Of course it’s big news whenever Trek releases a new Fuel EX, and given how important this bike is for the US brand, we were curious to see how the raft of updates would play out on the trail. We had a bit of an idea, having thoroughly enjoyed riding the electrified Trek Fuel EXe over the past few months. Would the muscle-powered version deliver the same good vibes? And how would it compare to the previous models that have given us so many fond riding memories over the years? We’ve been putting the Trek Fuel EX 2023 to the test to find out!

Watch our video review of the Trek Fuel EX 2023:

Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike.

An overview of the Trek Fuel EX 2023

For 2023, the Trek Fuel EX is built around an entirely new frame that’s produced in carbon and alloy variants. Suspension travel has increased by 10mm at both ends, with the new Fuel EX now sporting a 150mm fork and 140mm of rear travel via the ABP four-bar suspension design.

It’s worth noting that the frame will handle a 160mm travel fork, and thanks to the two-position Mino Link, it can also be run as a mullet. Borrowed from the Session downhill bike, there’s a two-position flip chip at the lower shock mount that offers linear and progressive settings. The latter option is what makes the new Fuel EX coil shock compatible.

On top of that, Trek will be offering aftermarket headset cups to steepen or slacken the head angle by a degree. Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike. It’s certainly an appealing package on paper, and one that’s ready to take on contemporaries like the Specialized Stumpjumper , Merida One-Forty , Canyon Spectral and Giant Trance X .

Trek Fuel EX price & specs

There are a number of different models available in the Trek Fuel EX 2023 lineup, though availability will vary depending on where you are in the world.

In Australia, prices currently range from $4,999 AUD for the Fuel EX 7, and go up to $8,999 AUD for the Fuel EX 9.8 XT model. The cheapest option is actually the Fuel EX 5, though that model carries over the previous generation frame. For a closer look at the specs, prices and all the new details, check out our Trek Fuel EX 2023 overview article for more.

Here we’ll be diving into our experience of testing the Trek Fuel EX 9.9 XX1 AXS model, which will be available in Australia in limited quantities through the custom Project One bike builder. It’s a media bike that was provided to us by Trek, and of course it comes dripping with lots of gold, carbon and wireless bits. However, as usual with our reviews, we won’t be going into detail about the Gucci-level spec. Instead, we’ll be concentrating on the important aspects that are shared throughout the Fuel EX lineup; the frame design, suspension performance and its on-trail handling.

The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Trek Fuel EX size & geometry

From X-Small through to XX-Large, the Trek Fuel EX is produced in no fewer than seven different sizes. Seven! Given that many brands only offer four or sometimes even just three frame sizes, that’s impressive.

The two smallest sizes feature 27.5in wheels, while the Medium and above come standard with 29in wheels. The Small is the only option that is available in either wheelsize.

At 175cm tall I’ve been riding a Medium, which features a 450mm reach. Thanks to the use of short seat tubes, a rider of my height could easily upsize to the M/L size to get a longer 470mm reach. Personally, I’ve found the fit of the Medium to be spot-on.

As for geometry, the Fuel EX features a 64.5° head angle and approximately a 77.5° effective seat tube angle in its stock configuration. The rear centre length varies between sizes, going up to 450mm on the largest frame. On the Medium I’ve been riding, the rear centre is a compact 435mm.

Coming off the Fuel EXe, I found it easy to settle into the Fuel EX. The only modification I needed to perform was to chop the comically wide handlebars from 820mm down to a more reasonable 780mm.

Suspension & tyre setup

Getting the Fuel EX set up is made easy thanks to Trek’s detailed online suspension calculator . Input the bike model and your riding weight, and out spits suggested air pressure and rebound settings for both the fork and shock. It even suggests tyre pressures, giving you a good place to start before hitting the trail. When brands like Canyon struggle to provide any recommendations at all, Trek should be commended for helping riders to get the most out of their bike.

For my 68kg riding weight, Trek suggests setting up the Fox 36 fork slightly softer and slower than usual. Recommended rear shock sag is 29%, and the calculator’s suggestion of 158psi got me to exactly that figure. Initially I set the rebound at 6/15 clicks as recommended, but while everything felt quite balanced front to back, the suspension was a little sluggish and duller than I wanted. Speeding up the rebound by a couple of clicks in both the fork and shock helped to make the whole bike feel a bit more lively, while improving small-bump reactivity.

Although the Bontrager SE5 tyres feature reinforced Core Strength casings, I still fitted a CushCore Pro insert to provide some additional pinch-flat protection and insurance for the carbon rims. Tyre pressures were set as per Trek’s recommendations with 20psi in the front and 22psi in the rear.

Trek Fuel EX weight

Confirmed weight for our Trek Fuel EX test bike is 14.4kg. That’s with the tyres set up tubeless, but without the CushCore insert or pedals.

It’s on the heavier side for a high-end carbon trail bike, though the 2.5in tyres, stocky carbon wheels and AXS components aren’t exactly the lightest going. Of course weights do vary throughout the Fuel EX lineup depending on the spec, and you can see the weights for all the different models in our range overview .

A contributing factor to the overall weight is the new frame, which has gained almost 700g over its predecessor. Trek claims the carbon frame weighs 3.4kg with the rear shock, making it a bit of a porker alongside some of the competition;

• Scott Genius HMX Carbon: 2,249g
• Specialized Stumpjumper Carbon: 2,280g
• Giant Trance X Advanced Pro 29: 2,498g
• Specialized Stumpjumper EVO Carbon: 2,750g
• Canyon Spectral CF: 3,047g
• Trek Fuel EX Carbon: 3,400g

The new alloy Fuel EX frame is heavier again, coming in at a hefty 4.6kg with shock.

Of course weight isn’t everything, and it’s unsurprising that the new frame has gotten heavier given how much longer and slacker it is. Still, for those who are especially concerned by grams, there are certainly lighter options on the market.

What do we dig about the Trek Fuel EX 2023?

With its added heft and updated geometry, the Trek Fuel EX 2023 is no doubt the burliest iteration yet. The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Indeed it’s massively capable for a 140mm travel bike, with the slack 64.5° head angle and roomy wheelbase giving it a purposeful stance on the trail. The geometry is superb, with welcome updates that have brought the Fuel EX right up to speed.

The steeper seat angle is particularly noticeable over the old bike, providing a much improved seated position on steep climbs. Pedalling efficiency has also levelled up. Trek has lifted the main pivot above the chainring to increase anti-squat, which helps to reduce pedal-induced bobbing. The Float X shock has a two-position climb switch, but I never once needed to use it while riding off-road since the rear end is so well behaved.

It rips through the turns

Once up to speed on flower singletrack, the taut chassis means the Trek Fuel EX is highly responsive when rounding corners and pushing into berms.

With its boxy downtube, split top tube and the supporting strut for the lower shock mount, the front triangle is heavily braced to resist torsional flex. Along with the wide main pivot and boxy one-piece chainstays, the Fuel EX possesses a strong spine from its shapely head tube to the rear thru-axle. The muscly frame effectively translates handling inputs while resisting lateral deflection through the turns.

Likewise, the short rear end and generous 38mm BB drop are fantastic when threading your way through twisty sections of trail, keeping you connected to the terrain and contributing to the playful ride quality. The low-hanging BB did mean I caught the pedals occasionally, so those who frequent off-piste terrain and technical climbs will want to consider flipping the Mino Link into the High position to indulge in an extra 7mm of pedal clearance.

Otherwise the riding position and weight distribution are totally sorted. The handling is approachable, and the Fuel EX doesn’t demand a whole lot from you as the rider. Compared to the old bike it does need a more concerted lean when entering tighter corners, though this is a part of the natural evolution of modern trail bike geometry. Even if you’re coming off a 5-year old bike, you’ll only need a few rides to get accustomed to the Fuel EX’s steering behaviour.

Trail-tweakable

In addition to the Mino Link, we’ve also been experimenting with the lower shock flip chip on the Trek Fuel EX. Requiring just a single 6mm hex key, it’s a quick adjustment to make trailside, and the change in suspension behaviour is noticeable.

I ended up preferring the ‘Less’ setting, which provides a more linear leverage rate. With the shock set at the recommended sag, this position provides great pedalling support, along with more comfort and activity deeper into the stroke. There’s still a good deal of progression though. Combined with the large bottom-out bumper in the Float X shock, hitting full travel proved to be a well-controlled affair.

One of our fellow testers, who generally spends more time in the air than on the ground, preferred riding in the ‘More’ setting. This increases progression, providing a stronger ramp-up in the latter half of the travel. He also reduced the shock pressure by 5psi to further enhance small-bump compliance, while still being able to enjoy the additional big-hit support. Pedal efficiency isn’t as stable in this setting, but it does mean the Fuel EX takes to jumps like a duck to water, popping off lips enthusiastically and absorbing hard landings with a solid and flex-free touchdown.

One thing to note on the More/Less flip chip is that while you are altering the progression of the air spring, you’re also affecting the damper too. As well as adjusting air pressure, we found we needed to tweak the rebound and low-speed compression settings between the two positions. It is indeed a useful tuning tool, but it doesn’t dispel the need for air volume spacers entirely.

What does it struggle with?

With the Trek Fuel EX adopting a beefier frame, the added weight is noticeable compared to lighter bikes in this category. That’s compounded by the heavy-duty brakes, stocky wheels and chunky tyres, which mean there’s more inertia to overcome during micro-accelerations on an undulating climb.

For those who are looking for a sharper and sprightlier trail bike to whip through the trees along smoother singletrack, the latest Trek Top Fuel will be a better fit. In comparison, the new Fuel EX is a burlier beast that thrives on steeper and more technical terrain.

Curiously, it does feel stiffer than the electrified version, the Fuel EXe . Despite both our test bikes featuring carbon frames with a near-identical build kit, I’ve found the Fuel EX to transmit more trail feedback.

Some of this may be due to structural differences, and perhaps the more favourable sprung-to-unsprung mass ratio on the electric version thanks to the added weight of the motor and and battery. Either way, the Fuel EX doesn’t exactly exude off-camber compliance. As a lighter rider on very rocky terrain, I’ve found myself getting knocked around a little more than I would like.

This sensation reminded me of the Canyon Spectral 125 , which proved to be overly stiff and quite uncomfortable at slower riding speeds. The Fuel EX is more compliant overall than the Spectral 125, but it’s still pretty stiff.

It’s not as supple as Fuel EX models gone by

Contributing to this sensation, the suspension isn’t as plush as previous Fuel EX models, particularly those that featured the Thru Shaft shock. Those bikes did require the rider to make use of the compression lever to provide pedalling support, but it meant that in the open mode the rear end absorbed the terrain like melted butter.

You may have noticed that Trek has been making a conscious move away from proprietary suspension components lately, and that’s coincided with building bikes that offer more neutral pedalling performance. The increased anti-squat is one part of the equation on the new Fuel EX, and the other part is the custom-tuned Float X, which Trek has configured with a digressive compression tune on the main piston. This creates a decent low-speed threshold, which provides a level of support that sits between the Open and Medium settings on the previous RE:aktiv damper.

The result is that you can ride with the shock fully open, and the Fuel EX still offers great stability under pedalling inputs, with no real need to activate the climb switch. If you detest remote lockouts and having to flip shock levers all the time, this will certainly be appealing.

The downside is that the suspension isn’t as supple over smaller rubble and at slower speeds. Along with the stiff chassis and carbon wheels, more of those vibrations are transmitted to the rider. As such, careful consideration with tyre pressure is needed to maximise grip and comfort.

Because there is more support however, the Fuel EX gives your feet a stronger platform to push off of, with greater feedback during high-load scenarios. Indeed the harder and faster you push, the better the Fuel EX responds. In that sense, it’s less of a comfy cruiser like its predecessors, and more of a mid-travel bruiser that loves to ride hard and fast.

Component highs & lows

As a complete bike, the Trek Fuel EX is a solid package that puts the emphasis on capability over light weight.

The Bontrager SE5 tyres are a good example, coming in at 1,100g each on our workshop scales. They roll reasonably well given their weight and size, and we’ve found them to provide consistent grip on rocky, hard-packed soil, which will suit most Aussie trail riders. The tread is a little shallow though, and the compound isn’t the softest, which sees them struggling to latch on when the conditions are wet and loose. We’d prefer something a little stickier and toothier up front, like a Maxxis Minion DHR II with 3C MaxxGrip rubber.

While the carbon Bontrager Line Pro rims are quite stiff, they have proven to be plenty tough. We’ve tested five of these wheelsets across various bikes over the past few years and we’ve not encountered a single issue. The y also come with a two-year crash replacement guarantee, which is great insurance given the hell that you can put this bike through. Furthermore, the frame itself comes with a lifetime warranty for the original owner.

There’s still plenty of real-world protection though, including a generous two-piece armour plate that bolts to the underside of the downtube. There’s also a metal chain-suck guard behind the chainring, and a full-coverage chainstay protector. Along with the fully guided internal cable routing, the Fuel EX is an impressively quiet and rattle-free bike on the trail. Well, except for the rear thru-axle lever, which I removed after the first ride.

Otherwise the finishing details are all sound. The adoption of a bigger 34.9mm seat tube diameter is welcome, as it accommodates a stiffer and stronger dropper post, particularly for the larger sizes. Mechanics will be happy to see a threaded BB shell, and we’re fans of the downtube storage. The trap door has none of the play that we encountered on the last Fuel EX we tested, with a tight fit and a nice lever action.

It’s certainly a high quality chassis, and many riders are likely to appreciate the in-built versatility. We’re looking forward to trying out the adjustable head angle once the aftermarket cups become available, and we’d also be keen to try out the Fuel EX with a coil shock. Setting it up as a mullet will be more straightforward, especially as you only need to buy an air spring to extend the Fox 36 up to 160mm of travel.

Trek Fuel EX vs Specialized Stumpjumper

Alongside the Trek Fuel EX, the Specialized Stumpjumper is one of the most popular and well-known trail bikes in this category. In terms of travel and the overall build, the Fuel EX sits right in between the regular Stumpjumper and the Stumpjumper EVO. However, it’s the regular Stumpy that I’ve been spending the most time on lately, both in its stock configuration and with a burlier mullet setup .

Compared to the Fuel EX, the Stumpjumper has a touch less travel with a 140mm fork and 130mm at the rear. It also uses a simpler suspension layout, with the carbon models employing a flex-stay design. Combined with its slimmer tube profiles, the carbon Stumpjumper frame is very light. Specialized claims it weighs just 2.28kg including the shock, which is over a kilo lighter than a carbon Fuel EX.

This theme extends to the Stumpjumper’s build kit, with Specialized electing for the skinnier Fox 34 over the 36. Along with an in-line shock, lighter brakes, wheels and tyres, there’s a considerable difference in the overall bike weight. For example, the Stumpjumper Pro we tested weighed 12.84kg.

While the geometry is pretty similar between the two bikes, the Specialized Stumpjumper rides much lighter on the trail compared to the Trek Fuel EX. It offers more comfort, with its lithe chassis and smooth suspension performance providing better compliance over rough terrain. It’s quite sporty and sprightly, though its active suspension design does need taming on the climbs by making use of the rear shock’s compression lever.

In comparison, the Fuel EX is more naturally efficient. It’s also more planted at speed, with its sturdy chassis and supportive suspension providing better big-hit capability. It feels more like a short travel enduro bike, which will suit heavier and harder riders.

Both bikes will handle a longer fork and can be set up as a mullet, though Specialized makes a specific link for the Stumpjumper to maintain the stock geometry. There is greater versatility in the Fuel EX chassis, with the option to adjust the head angle and fit a coil shock.

As for value, the Fuel EX offers a more appealing spec package. A Stumpjumper Expert sells for $9,800 AUD and comes with a Fox 34 GRIP2 fork, SRAM G2 brakes, an X01 drivetrain, alloy wheels and handlebars. In comparison, an equivalent Fuel EX 9.8 XT sells for $800 AUD less. It gets a simpler GRIP damper for its Fox 36 fork, though it does feature a piggyback shock, a Shimano XT groupset, a carbon one-piece RSL cockpit and carbon wheels with that 2-year crash replacement guarantee.

Flow’s Verdict

For many trail riders, the Trek Fuel EX 2023 is likely to tick just about every box on your new bike wish list. It’s as up to date as it gets, featuring loads of adjustability, internal storage and a nuanced approach to its size-specific geometry. Along with the increased travel and muscly frame, it offers greater stability and big-hit control over its predecessor, while still being a fun and involving bike to ride on modern flow trails.

It is a bit of a chonker though, so those who are looking for a lightweight and speedy trail bike may be better served by the latest Top Fuel .

The stiff chassis and supportive suspension also mean the Fuel EX tends to transmit more feedback, making it less comfortable to ride over rocky terrain. We’d be curious to try out a lighter shock tune to see how much of a difference that would make to the overall ride quality, but in its stock form the Fuel EX isn’t as plush as competitors like the Giant Trance X and Specialized Stumpjumper .

It is impressively efficient though, and the stable suspension gives you a load of support when you’re really giving it the beans on the descents. In this sense, the Fuel EX is closer in feel and performance to an enduro bike. You’ll still want to look towards the Slash if you’re serious about racing, but outside of the tape the Fuel EX will handle just about everything a modern trail centre or bikepark could throw at it. And for those who really want to up the limits, the adaptable chassis can easily be configured for some pretty aggressive riding.

Indeed for those who are chasing maximum capability without going to a big, spongy enduro bike, the Fuel EX is a mighty appealing option.

Tested: Trek Top Fuel

Don't call it a race bike. Trek's new Top Fuel is for railing steep fast decents with no course tape in sight.

Takeaway: Trek’s latest edition of the Top Fuel moves from being a big cross country racer and becomes a short travel trail bike. With new longer and slacker geometry, plus 5mm of extra travel, it aims to give riders the efficiency they want for long days while still enabling them to ride more technical trails with confidence.

• Fully guided internal routing in the front triangle plus a 73mm BSA threaded bottom bracket simplifies maintenance for both professional and home mechanics.
• The new Top Fuel has clearance for 2.5” tires; which makes perfect sense as even XC racers are now running 2.4” tires as standard.
• The downtube storage compartment is now featured on all Top Fuel models, including the alloy versions. It’s a great feature that often gets nixed on lower priced frame models.

Price: $11,500 Weight: 26.8lbs (size XL) Style: Full suspension 120mm trail bike Frame: OCLV Mountain Carbon, internal storage, tapered head tube, Knock Block 2.0, internal guided routing, downtube guard, magnesium rocker link, Mino Link, ABP, Boost148, 120mm travel Wheel Size: 29” Fork: RockShox SID Ultimate, DebonAir spring, Charger Race Day damper, tapered steerer, 44mm offset, Boost110, 15mm Maxle Stealth, 120mm travel Rear Shock: RockShox Deluxe Ultimate RCT, 185mm x 50mm Drivetrain: SRAM Eagle AXS, wireless, 12-speed Cranks: SRAM XX1 Eagle, DUB, 55mm chainline, 175mm length Chainring: 30 tooth Cassette: SRAM Eagle XG-1299, 10-52T, 12-speed Brakes: SRAM G2 Ultimate hydraulic disc, carbon levers Front Wheel: Bontrager Line Pro 30, OCLV Mountain Carbon, Tubeless Ready, 6-bolt, Boost110, 15mm thru axle Rear Wheel: Bontrager Line Pro 30, OCLV Mountain Carbon, Tubeless Ready, Rapid Drive 108, 6-bolt, SRAM XD driver, Boost148, 12mm thru-axle Tires: Bontrager XR4 Team Issue, Tubeless Ready, Inner Strength sidewalls, aramid bead, 120tpi, 29.x2.40'' Saddle: Bontrager Arvada, austenite rails, 138mm width Seatpost: RockShox Reverb AXS, 170mm travel, wireless, 34.9mm, 480mm length Handlebar / Stem: Bontrager RSL Integrated handlebar/stem, OCLV Carbon, 27.5mm handlebar rise, 820mm width, 0 degree stem rise, 45mm stem length

While XC race bikes were becoming longer travel, yet another new category of mountain bikes started to gain traction with riders: down-country. This new breed of bikes combines elements of longer travel all-mountain and trail bikes (such as slack geometry, more powerful brakes, and heavier casing tires) with shorter travel and lighter-weight frames. Essentially, burly XC bikes that you can ride all day, are efficient climbers, and very capable at descending. This is the approach Trek took with the latest Top Fuel.

The new Top Fuel strikes a similar silhouette to the older model, with a vertically mounted shock layout and Trek’s Active Braking Pivot suspension system; which now delivers an extra 5mm of travel in the rear to match the 120mm travel fork. The Top Fuel’s geometry is in line with other bikes in the emerging down-country category, with the headtube angle becoming 1.5 degrees slacker and reach increasing by 10mm as compared to the previous generation of the bike. The Top Fuel now also has clearance for 2.5 inch tires, for those who want to push traction to the limit.

The new Top Fuel edges ever closer into the territory of its longer travel sibling, the Fuel EX. The updated geometry of the Top Fuel actually makes the Fuel EX look a bit dated in comparison. The two bikes have identical headtube angles, with the Top Fuel having a longer reach and a steeper seat angle as well. You can even fit a 130mm fork on the Top Fuel, which would make it slacker than the Fuel Ex. Basically, the Top Fuel is no longer a race oriented bike. It has now morphed into an efficient trail bike for riders that still want solid pedaling performance to get up the climbs, but who want additional speed, confidence, and control on the descents.

Builds & Pricing

There are a total of nine different Top Fuel builds offered by Trek, plus carbon and alloy framesets. The Top Fuel is also available through Trek’s Project One program, allowing riders to customize everything from components to paint.

We got to test the Top Fuel 9.9 XX1 AXS build, which at $11,050 is (depending on your perspective) either a reasonable price for a modern high end bicycle or completely bonkers. With bikes such as Specialized S-Works Epic EVO coming in at a cool $13,000, and the Scott Spark 900 Ultimate EVO AXS at $14,000, the Top Fuel 9.9 almost seems price conscious.

The cheapest Top Fuel model, the alloy framed Top Fuel 5, features a RockShox Recon fork, X-Fusion X-Pro2 shock, and a Shimano Deore drivetrain at $2,630. The Top Fuel 7 has a Recon Gold fork with a mix of Shimano SLX and XT parts, plus Bontrager Line Comp wheels for $3,530. The Top Fuel 8 is the priciest alloy build at $3,830, with a RockShox SID fork and Deluxe Ultimate shock plus more powerful Shimano M6120 four-piston brakes.

The Top Fuel 9.7 is the most affordable of the carbon builds at $4,230. It uses Fox Rhythm 34 fork with a Float DPS shock and is finished with a mix of Shimano SLX and XT, plus Bontrager Line wheels. The Top Fuel 9.8 has three different versions based on your component preferences. You can go mechanical with SRAM GX or Shimano XT for $7,050 or upgrade to GX AXS for $7,550. All three use RockShox SID Select+ forks and Deluxe Ultimate RCT shocks, along with Bontrager Line Elite 30 wheels. Moving to the top of the price range, for $9,550Trek offers the Top Fuel 9.9 XTR build for Shimano and Fox lovers. It uses Fox Factory level suspension, a full mechanical XTR drivetrain, and Bontrager Line Pro 30 wheels. Riders preferring Rockshox Ultimate level suspension and electronic XX1 AXS shifting will need to spend $11,050 to get the most expensive Top Fuel model, the 9.9 XX1 AXS.

If you’d rather build your bike from the frame up, Trek offers alloy and carbon framesets. The Top Fuel AL frame sells for $2,320 with a Fox Float DPS shock. The carbon frame is priced at $3,720 and includes a Fox Factory Float DPS shock.

Geometry & Fit

The new Top Fuel has received the slacker and longer treatment, and as a result, the head tube angle is now a degree and a half slacker at 66º across the entire size range. Reach grows by 10mm while BB height and chainstay length remain the same from the previous generation.

Trek offers seven different sizes of the Top Fuel, including an M/L option for riders often caught between the medium and the large. With a stock stem length of 45mm on all sizes except an XS, our 6’3 tester felt cramped on the size XL and likely would have benefited from sizing up to an XXL. The issue was resolved with a longer stem, but the most expensive 9.9 builds of the Top Fuel Trek use its integrated Bontrager RSL handlebar and stem combo. It’s easy enough to swap out as it thankfully doesn’t run any lines internally, but it still means riders will need to supply both a bar and a stem to make fit adjustments. As always, it’s highly recommended that you get a test ride in at a shop before buying a new bike if possible.

Ride Impressions

The new Top Fuel is very much a short travel trail bike meant for ripping down burly trails. Thanks to a 40mm increase in wheelbase, a slacker head tube angle, and other geometry changes over its previous version, it feels much more planted and composed on rough and fast descents. It’s a bike that wants to hold a line and stay planted on the ground. This worked well in certain situations, like scrubbing speed on a rough bit of trail heading into a turn. Other times it made me have to fight the bike a bit to make quick line adjustments.

To highlight the new trail bike character of the Top Fuel, Trek has made some component choices to suit the bike's new intended purpose. Opting for four-piston SRAM G2 brakes, as well as grippier XR4 tires, for better control on steep descents. The frame is also beefed up with a larger downtube that now includes a storage compartment for snacks or, more likely, flat-fix tools. The seat tube also grows in diameter to increase stiffness and accommodate a larger diameter 34.9mm dropper post. The remote lockout is also gone from the handlebars – which, perhaps more than any other change, makes the Top Fuel's intent as a trail bike crystal clear.

Trek’s ABP suspension design has had many years of refinement and is a genuine four-bar platform, unlike many 120mm bikes that use a flex pivot. In contrast, all the pivot points on the Top Fuel use sealed bearings, resulting in a suspension setup that feels much more active. The design does a good job of isolating braking from the suspension, resulting in less skipping and bouncing when you’re hard on the brakes in a rough section of trail.

The downside of the Top Fuel’s trail bike transformation is that it’s now a bit heavy. Our premium 9.9 XX1 AXS XL sample came in at nearly 27 lbs. This isn’t wildly heavy for a trail bike, but typically you get a bit more suspension travel with that weight penalty. For reference, the Scott Spark I tested earlier this year has the same amount of suspension travel as the Top Fuel but is a full three pounds lighter. Trek does say that the Top Fuel is compatible with a 130mm fork, and I can’t help but think the new Top Fuel would have made a lot more sense with the increased travel straight from the factory.

After having multiple testers on the Top Fuel over the last few weeks, our consensus has been that the Top Fuel would thrive in a place that has a lot of machine built or well maintained, and steep trails. Trails where you can get the Top Fuel moving fast allow the progressive all-mountain geometry to shine and make the bike feel much more capable than its 120mm of travel would suggest.

The new Top Fuel is undoubtedly more capable than its previous version while maintaining much of its pedaling efficiency. Riders with more than a casual interest in racing should probably look at bikes such as the Scott Spark , Canyon Lux Trail , or Specialized Epic EVO . The Top Fuel is perhaps the ideal bike for riders who want a trail, or even all-mountain, bike geometry experience, but don't want the extra weight or need the extra bit of travel.

Trek Top Fuel vs Gen5 Fuel Ex

• Add to quote

mtb128pedal said: Liking the Fuel EX 8. Went from 780mm bars to 750mm. Need to cut to 700mm. Added a Top Fuel knock block thing for the blender computer mount. A Top Fuel would work but the extra suspension will come in handy. View attachment 2020624 View attachment 2020622 View attachment 2020623 Click to expand...

I owned the previous gen TF (2020 115/120mm) actually traded it for a Gen 5 just to switch up and make the overall stable a little more versatile. Wasn't riding the TF since I had purchased a new Ripley. I originally didn't think keep the Fuel around long but every time I ride it don't want to get rid of it. In General it is a question of what is more important, some versatility lots of speed, more versatility but more forgiving and comfort. Some info for consideration: I think the Fuel EX (gen 5) gets a bad online rep. Based on limited reviews versus rep from riders who own and ride one. It is definitely a pure do it all trail bike. Jack of all Master of none. It wont pedal like a short travel bike, it wont descend like a long travel slacked out bike. It will be versatile and keep your riding through any real trail system. Has active rear suspension for tech climbing and plowing through the trail and is plenty firm if you have a shock with compression adjustment switch. If you want short travel firm pedaling bike that can still descend and speed is the most important factor for you TF. If you want a more pure trail bike where steady all day long efforts still reward hard pedaling but comes at expense of slower climbing but more forgiving bike than Fuel. I would also argue I bet can find deals on the old Fuel EX or great deal used as everyone is liquored up on the new Fuel Gen 6 which IMO is just a totally different bike.  

We’re loving the TF but haven’t ridden the FEX, so no comparison here. It feels very quick but stable. One is likely a slightly better climber and the other a slightly better descender. Your best choice depends on riding style and priorities. There’s probably a two-pound weight penalty for the extra travel, so consider which matters more to her. A skilled rider will love both and outride me on either model. Recently a guy on the Sig Sauer forum replied to a post asking which pistol of two similar models was more accurate by saying all of mine are more accurate than I can shoot.  

The new Top Fuel actually weighs .88lbs more when comparing the aluminum models. TF8 vs EX8 Thanks for sharing your info on your bike.  

I own both. The TF's pedaling is quite a bit more lively or snappy. The FEX is a bit smoother. For me, the snappy pedaling trumps the smoothness factor. Note that I set my TF up with a 130 mm fork right out of the gate, and I believe all 2023 TFs are coming that way stock. I believe frame weights are darn near identical.  

I’m hoping they will release a 2023 TF8 that is 130. Right now you have to get a 9.8 or higher to get a stock 130. Thanks for posting your perspective  

I don’t understand why they are suddenly putting 130mm forks on the TF, what was wrong with 120mm ?  

They've also switched from SID -- rampant bushing problems -- to Pike forks -- pretty bombproof. I know I like my TF with a 130 fork, and that's possible with the Pike, but not with the SID.  

What you end up getting? I'm looking at the TF8 or FEX8 Gen 5 too. And to throw in a little wallet creep the TF9.7. I like the 9.7 but afraid at 210 lbs I'd fall on it a break some carbon. Like the TF8 has the threaded BB. Did some short test rides of both on pavement, rough grass and on and off curbs. I like the quicker steering of the TF. FEX is a little cushier. My current ride is an old cobbled together bike with a Performancebike frame and 60mm travel Tora. I have not broke it like the 5 Raleigh warranty frames before. So 120mm travel looks like a downhill bike to me.

Bikes have gotten heavier. May be the creep of suspension travel or I hope ruggedness. InN 2018 the Slash still had more travel. More than I'm looking for.  

So what ya get. I’m still on the fence. Bumped my Tora fork to 225 psi (the correct pressure) and added a PNW Coastal dropper to my 26er hard tail. A little compliance (40mm) in the post helps.  

I have a the fuel ex 8.9 and have really enjoyed the bike. Great geometry and reliable components. However a bit heavy for true xc riding and more travel than most really need. TF has my interest.  

Tough choice. I came close to a TF 9.7. Chickened out and went aluminum. Changing from 2.6 tires to 2.4 or narrower tires and lighter wheels will lighten it. Oh I have some GR1 35 mm tires on my stick Domane wheels. Wonder how they would fit on the Fuel EX wheels. I think if I want something more XC I’ll get a Super Caliber. N+1.
