High value, high performance, and impressive versatility– those are three features many would love to see in a mountain trail bike. But does Trek Fuel Ex 5 hold up to its marketing in a review– or are there better options?

Trail mountain biking is nothing new. But in the past decade, trail mountain biking has steadily grown from a niche activity to one loved by many. You only need to look at 2020 mountain bike riding statistics to get a picture of just how impactful trail biking has become and what it means for many. 

Trail riding is unsurprisingly the most popular of all types of mountain biking , including enduro, downhill , and more. In a survey, over 92 percent of cyclists participated in the trail ride, a little over 56 percent in enduro, and 30 percent in downhill in 2 years. 

But what’s driving so many to hit the trails? Trail riding is the most accessible for new riders, requires less heavy-duty equipment, and poses a lower risk of injury vs something like downhill riding. Mountain biking of all forms is a means of exercise, exposure to fresh air, and enjoying the community. 

But even though the survey also indicated mental health benefits– with over 92 percent of respondents saying cycling helps balance negative emotions–there remains a barrier. Mountain biking is expensive, and not everyone can afford the equipment. But even if you can, you don’t want to overspend– and you also want to find a bike that will provide a smooth, stable ride.

That’s why I want to look at Trek Fuel Ex 5 , a trail bike that claims to be of great value. This guide will tell you my selection criteria for finding the best trail bike and review how Trek Fuel Ex 5 compares.

Fuel EX 5 is a full-suspension trail bike that's ready to handle it all. The Fuel EX 5 hits the mark as a high-value, high-performance mountain bike with exceptional versatility.

What is trail mountain biking?

When you think about mountain biking, you may picture steep inclines and declines and even jumps. But in between that rigorous biking and road biking is trail mountain biking. Trail riding is a general term that encompasses off-road riding.

Dirt and grass path away from a hectic life. Unlike with road biking, you’re not going to encounter cars– though you could encounter other cyclists if you pick a popular TRS that are most common, and they may feature twists, turns, and inclines or declines– but that isn’t the main focus.

The concept of trail riding is providing timail. You’ll contend with various terrain, and trail mountain biking is more challenging in terms of technique and balance– but also slower than road cycling. 

Is mountain biking a better workout than road biking?

Whether or not mountain biking is considered a better workout vs road biking, as you can imagine, is somewhat a matter of perspective. That is: how do you define a good workout? For some, it’s calories burnt. Others are worried about muscle gains or enjoyment.

All of these, and, of course, cardiovascular fitness, are valid factors. Mountain biking is more ideal for muscle development and a full-body workout. You’ll use more upper body strength, while road riding is mostly focused on lower legs and cardiovascular endurance. 

You can cover more ground more quickly road cycling, but the ground you’re covering riding on trails is more challenging. Holistically, mountain biking is considered a slightly better workout– with the added advantage of scenic and quiet locations. Still, road biking can be an excellent workout if you enjoy it more or if that’s simply what you have access to. 

Do I need a trail bike?

The first step is to assess whether or not you need a trail bike. Chances are if you’re considering a trail bike, it’s for good reason. If you already have a road bike it may be tempting to take it out on a trail- but that’s not a good idea. While bike categories may seem arbitrary, they exist for a reason.

Road bikes are typically made with a lightweight aluminum frame or other lightweight material, slim tires, and dropped geometry. A road bike is designed to reduce friction and optimize speed– so it’s not going to hold up well on uneven terrain. Road bikes simply don’t provide the traction and control you need for trail riding.  

What is the difference between a trail bike and a mountain bike?

Mountain bike is an umbrella term for many types of bikes. A trail bike is a form of a mountain bike, so it’s a misnomer to say the two are different. So instead, I want to take a look at specific bike types and how they compare with a trail bike. 

What is the difference between enduro and trail MTB? 

Enduro mountain bikes are hardy bikes designed for downhill riding. They’re notable for their long travel and also accelerate at steep inclines. Enduro bikes are bulkier than general trail mountain bikes but are also more efficient, designed for trail racing competitions. You should get an enduro if you plan on racing or want to take on steep descents and inclines.

If you just want to ride recreationally on moderate trails, a trail bike will save you money, storage space and is a bit easier to learn how to ride.  All-mountain bikes are included in the general category of enduro (which refers to racing), so the differences between trail and all-mountain bikes are the same as for enduro. 

What’s the difference between a trail bike and a motocross bike?

Motocross bikes have a very specific purpose. These bikes are a form of a motorcycle and are ridden on muddy tracks with controlled conditions. Not only are they motor-operated, but they also feature bulky tires and handlebars and are bulky.

Dirt bikes are in between– nonmotorized bikes meant to tackle muddy conditions with knobby tires and a heavy frame. Trail bikes are far lighter and a bit more versatile, meant to tackle different trial types, and also designed for riding in fair to moderate conditions. 

What’s the difference between XC and trail?

XC, or Cross Country , is a popular mountain bike type known for its versatility. XC bikes are ridden on trails and roads, making them a great crossover bike– though they’re more efficient on trails and not meant as a replacement for road bikes. It depends on the model you’re looking at.

Still, XC bikes are more lightweight and accelerate more easily than your average trail mountain bike. XC bikes are used for tortuous paths, but they’re not equipped for climbing or descending as much. XC bikes are used more for racing, while trail bikes are used for general rides and focus on control and greater shock absorption. 

What is a trail bike good for?

A trail bike is the most popular type of mountain bike for a good reason. It’s less specialized than other mountain bikes and can be used for most trails. Trail bikes can climb up or descend, though they aren’t intended for racing or especially steep inclines and declines or as inclement weather. Think of a trail bike as a recreational bike that’s harder than a road bike and offers more stability than a racing XC bike. 

Can you jump a trail bike?

Technically you can jump just about any bike, but there are bikes designed for jumping. Trail bikes are not a great option for jumping, as they don’t have the acceleration and inertia to get much air. And while they offer control, that control isn’t designed for performing jumps. At most, you could do some modest jumping. If your main objective is to find a bike for jumps, I recommend a dirt bike. 

Can I take a trail bike to a bike park?

While trail bikes are more versatile than some mountain bikes, they aren’t designed for road or bike parks. Trail bikes do perform at their best on trails. 

Can you use a trail bike for downhill?

Trail bikes climb and descend efficiently. They offer control, but they’re not meant for the very steepest trails, nor are they designed for purely downhill biking. The key here is to understand that trail bikes value control over speed.

You can’t expect to do downhill racing, but a good trail bike can handle inclines and declines. 

How do I choose a trail bike? ( My Buying Criteria)

If you’ve decided that a trail bike is the right type of bike for you, make sure that you find a bike that’s going to last and provide stability. Before I review Trek Fuel Ex 5, here’s a succinct guide to my selection criteria for finding a great trail bike. 

What trail mountain bike size should I get?

Determining the right size is important for comfort and control, but it can also be tricky. Different brands have different sizing standards. Smaller frames or sizes may vary from manufacturer to manufacturer, so the best idea is to refer to that brand’s sizing guidelines. Click Here for Trek Mountain Bike Sizing . 

How important is bike standover height and the top tubes?

Another sizing consideration is the standover height. A bike’s standover height refers to the length of the top tube to the ground and most commonly included within sizing information. This is important and also can lead to a better fit.

A standover height that’s too great can risk injury, while a too short height can leave you feeling cramped. For straight handlebars, I recommend an inch to two inches of clearance

. This provides a good fit and proper visibility. A sign a bike is too small is if you’re sitting on the bike and easily able to touch the ground with your feet.

Is a 27.5 or 29er tire better for a trail bike?

For the tire size, your most common options are a 27.5 vs a 29er. Both are fine, but I mean more towards a 29er for a trail bike. A 27.5 tire is generally more efficient at accelerating, but a 29er is going to provide a bit more traction and control.

But size isn’t the only factor in finding the best tire type. A dual compound improves durability. You’ll want a tread pattern that offers grip and traction for turning corners and some sidewall support. Puncture resistance is ideal for trail riding too. 

What material is best for trail cycling?

You’ll have an option of aluminum, carbon, steel, and titanium for most mountain bikes. Of these, I’d recommend carbon the most for a trail bike. While titanium is a bit smoother and lasts just as long, it does get quite pricey, and may not be necessary for a trail bike.

Carbon is lightweight and, unlike steel, not prone to corrosion. Aluminum is attractive for being lightweight and budget-friendly– but I’d prefer aluminum for something like a road bike, as it’s more prone to damage. 

How many gears should a trail bike have?

Considering that mountain bikes can have up to 40 gears, it can feel like you need as many gears as possible, but that’s not the case. For a solid trail bike, I recommend around 20-27 gears.

This provides more control and versatility- needed for trail riding– but doesn’t require you to search long and hard and pay top dollar. Aside from the number of gears, also pay attention to the type of gears.

You’ll also have the option between single, double, and triple drivetrains. 

Of these, I recommend a double drivetrain. It’s a nice balance for a trail bike. You’ll have situations where you may need more than a single, but you also aren’t using a trail bike the same way you would an enduro bike. 

Are disc brakes better on a trail mountain bike?

Between disc brakes and rim brakes, I recommend disc brakes for trail bikes. They’re smoother, more reliable, and less likely to become damaged when riding on trails. Some even consider a bike on a trail without disc brakes to pose safety hazards– I’d consider this feature nonnegotiable.

But you will need to decide between mechanical vs hydraulic brakes. Hydraulic brakes use fluid for stopping power, while mechanical brakes are purely based upon traditional brake chain force. Hydraulic brakes tend to be smoother and more expensive, and they’re quicker to respond.

I prefer hydraulic brakes for a trail bike, especially if you get caught in inclement weather. That doesn’t mean mechanical brakes are bad– they’re just not as efficient. 

Is a hardtail mountain bike good for trails?

Full suspension tech is better for a trail bike if you have the money, though you can argue it’s not a must-have. With the full suspension, you’ll get both rear and front shock, equipping the bike with greater traction, steering control and making for a more comfortable ride for bumpy trails

. You’re adding weight and cost, but for many, those trade-offs are well worth it, especially since trail bikes aren’t intended for racing and quick acceleration. With a hardtail, you have a rear shock and a lighter setup. If you opt for a hardtail bike, I recommend sticking to even trails. If you’re doing fairly light trail riding, a hardtail may be just fine. 

How much travel do you need for trail riding?

Bike travel is measured to determine the distance from the front or rear suspension that will absorb force. Thus, the greater the travel, the more shock resistance.

Bikes with greater travel may not accelerate as quickly, but they provide a smoother, more controlled ride for uneven trails. 100mm is the minimum I’d go, but 120mm to 130mm is a great range.

Above 140mm isn’t necessary for a general suspension trail bike. 

How much is a trail bike?

As you can imagine, the price of a trail bike ranges depending on materials, construction and brand. Trail bikes are more expensive than road bikes, but they’re also less expensive than something like an enduro bike.

You’re unlikely to find a trail bike that quality features for under $1,500, but spending a bit more leaves room for some great upgrades. 

Are dropper seatposts worth it?

Dropper posts are sometimes used for mountain bikes to provide greater adjustments than your Seatpost. This can provide greater visibility and comfort, and for some avid cyclists, it’s worth it. However, for a trail mountain bike, it’s not usually necessary. 

How do I choose the right mountain trail bike seat?

There is no perfect saddle for a trail bike seat, as we all have different bodies and different personal preferences. There are three general categories for mountain bike saddles: performance, racing, and recreation.

Since trail bikes aren’t used for racing, opt for a recreation saddle, or a performance saddle if you like a little versatility. You’ll want some cushioning and shock absorption, with gel offering the best cushioning and foam second.

A synthetic material like nylon that’s weather-resistant is wise for a trail bike. A center cut-out will provide a lighter profile and some breathability. Still, a saddle without a cut-out has more overall cushioning. 

What is Trek known for?

Now that you know my criteria for finding the best trail bike, I want to examine Trek as a brand. If you’ve considered buying a mountain bike before, chances are you’ve heard the Trek name, and for a good reason. Trek is one of the most popular makes for mountain bikes of all kinds.

Trek is also known for its wide selection of entry-level bikes, which some competing brands don’t offer to the same extent. That is of course tied to the fact that Trek is the largest US-based cycling company. The Roth Distributing Company owns Trek. 

Where are Treks made?

Up until 2017, Trek bikes were all manufactured and shipped from Waterloo, Wisconsin. Now they outsource some of their manufacturing to Asian countries, so none of their bikes are fully made in the United States. 

Is Trek a good movie?

Trek retains its reputation as a solid brand for entry-level and more specialized mountain bikes. One way they’ve done so is by staying on top of new biking technologies while still offering bikes at an accessible range of prices. Their diverse inventory and willingness to improvise both highlights why Trek bikes remain well regarded and popular. 

How long does a Trek bike last?

Trek bikes don’t all last the same time because that depends on the materials used and how heavily the bike is used. There’s so much variability– for all brands– for these and other factors that it can be difficult to estimate.

While most Trek bikes are well made, you’re not guaranteed that a bike will last a certain length of time. Regular bike maintenance is critical for whatever model you purchase. 

Is the Trek Fuel Ex 5 Worth It?

Trek Fuel Ex 5 is a striking but approachable bike, marketed as a high-value and high-performing option. With a dropper post and other great features, is it all hype or worth your money?

What type of bike is the Fuel Ex 5?

The Fuel Ex 5 is a mountain trail bike equipped with a blend of higher-end and accessible materials and features. It’s touted as a gateway to a mountain bike. The wording makes me think that the Fuel Ex 5 is trying to cater to those new to mountain or trail biking, or perhaps those who want great features but not at an eye-watering price point. 

How much does a Trek Fuel Ex 5 cost?

Still, the price is higher than some trail bikes by a good $1,000, so it’s important to investigate every feature offered. Prices are subject to change and vary based upon your make and specifications. Still, you’re looking at spending roughly $2,500 as of the end of 2021/ early 2022. 

What material is the Trek Fuel Ex 5 made out of?

The Trek Fuel Ex 5 features a lightweight aluminum frame, which surprised me for a few reasons. For one, at the price point, I expected perhaps a carbon fiber frame. But it also is a little heavy for its make.

Aluminum isn’t a terrible choice if you’re starting suspension trail riding. It is reasonable for moderate trails– but it can dent and become damaged by impact and debris. I do appreciate that aluminum won’t easily rust. 

How much does a Trek Fuel Ex 5 weigh?

The Trek Fuel Ex 5 comes in at 34 pounds and 6 ounces for medium frame size. This is interesting because the average weight for a full suspension trail bike with an aluminum body is between 29 and 33 pounds.

This makes the Trek Fuel Ex 5 a bit heavy for what you’d expect, especially considering it’s not a full-suspension bike. I would argue this isn’t the biggest problem for a trail bike, but it still should be noted.

Your ride will feel a little less springy than you might expect from an aluminum body. 

How much travel does a Trek Fuel Ex 5 have?

Here’s where the Trek Fuel Ex 5 shines: the travel. You get an impressive 140mm of travel, providing a smoother and more controlled ride. This is generous for a general trail bike, and an advantage over some competing bikes. 

Does the Trek Fuel Ex 5 have a dropper post?

The Trek Fuel Ex 5 likewise has a dropper post. By opting for a dropper post, you’re getting more versatility out of your seat positioning, as well as offering a slight advantage for visibility. While not a must-have, it’s a nice feature to have if you know how to use it effectively. 

What kind of drivetrain does the Trek Fuel Ex 5 have?

Trek Fuel Ex 5 has a Shimano 1×12 drivetrain. You’re getting 12 gear speeds and a single cassette. The 12 gears are sufficient for a trail bike for moderate trails, even if it’s not as generous as some models.

Shimano is a respectable brand and usually makes quality products. Their 12-speed drivetrain provides a stable and clean stop with new Hyperglide technology that’s meant to improve the single drivetrain experience.

For a single drivetrain, it’s a solid option, but I do wish they added a double drivetrain. 

What type of brakes does Trek Fuel Ex 5 have?

Hydraulic disc brakes are used for this model, which is a great upgrade for a mountain trail bike. The breaks are also manufactured by Shimano, which is another plus.

Is the saddle comfortable on the Trek Fuel Ex 5? 

The saddle is a Bontrager Arvada . This is a performance saddle seen on both road and trail bikes and is made with microfiber. Microfiber is known to be lightweight and fairly durable. While it’s not fully weather-resistant, it can repel water.

The rail is made out of steel, which is strong but also can corrode over time. The cut-out is designed for pelvic rotation and is focused on balancing comfort and efficiency.

It’s a reasonable saddle choice– not a stand-out, but suitable for regular trail riding. 

Arvada Comp adds comfort and reduces soft-tissue pressure by creating a strategic cut-out in the saddle shell. 

What are the tires like for Trek Fuel Ex 5?

The tires are a  27.5” Bontrager XR4 Comp , with a 30 TPI. The size is designed a little more for acceleration than traction. 30 threads per inch for the tire is on the low end. Utility tires are around 15 tpi, while the high end may be 120 TPI.

For general trail riding, you want a tire that falls between 60 and 120 TPI, and it is always a trade-off and balance. The highest tapis has less rolling resistance, while the lower end is less likely to puncture.

If you do buy the Trek Fuel Ex 5, you may want to consider if you can swap out the tires for a bit higher tpi. 

The XR4 Team Issue TLR tire offers incredible grip and fast-rolling efficiency in a new and improved tread pattern with 120 TPI casing. Save yourself from punctures with our Inner Strength sub-tread protection while squeezing out every bit of cornering traction with the 61a/50a dual-compound rubber. 

Frequently Asked Questions

Answer: This depends on the model you’re considering. If you look at a newer model of both, you’ll be getting a carbon body with either bike. They also both feature full suspension for a general mountain bike. The main difference is that the Trek Fuel Ex 9.7 and the Top Fuel 9.7 are in the wheels, travel, and gear capabilities. The Top Fuel comes with either 27.5 or 29ers, while the Top Fuel Ex has 29ers and more gear capabilities. The Ex is better for a trail bike, while the Fuel could be argued for as an XC bike. 

Answer: Ther Trek Fuel EX 9.8 features a carbon frame and weighs 28.94 pounds for a medium frame. 

Answer: This Trek model is a versatile trail bike with a platinum aluminum frame and 150mm travel. It weighs 31.92 pounds for a medium frame. 

Final Thoughts

The Trek Fuel Ex 5 has some great features going for it: hydraulic brakes, a dropper post, impressive travel, a respectable saddle, and well-designed gears. It is a bit limiting in other ways.

For example, an aluminum body frame but a heavier than average weight and low TPI tires make this bike a bit mixed in terms of features. It’s a decent bike for general light to moderate trail, and what’s here is mostly well done– I do wish it was a little cheaper.

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.

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.

Is Trek Fuel EX 7 Gen 5 A Good Bike? [Trek Fuel EX 7 Gen 5 Review]

Table of Contents

Trek Fuel EX 7 Gen 5

• Price: $3,499.99
• Frame： Alpha Platinum Aluminum
• Gears: 1 x 12 speed
• Tire: 29×2.60″ (max)

What we like about it: The smooth DebonAir spring and dropper design and the 1×12 SRAM NX Eagle drivetrain make for a great full-suspension bike.

What we don’t like about it: some people think it would be better if it had 4 piston brakes, we think the Trek Fuel EX 7 is perfectly adequate when braking.

Rating: （4.7/5)

Introduction

Did you know? When our reviewers rode it on country roads, passers-by saw our Trek Fuel EX 7 and said “Wow, look at that bike! Look at that bike!”. Its unique design and paint job are very attractive.

After two months of reviewing the Trek Fuel EX 7, we can see why some people call it a “stable and reliable utility bike”. of the bumpy feeling.

Not only that, but the Trek Fuel EX 7’s Alpha Platinum Aluminum body and vacuum tires reduce its overall weight, allowing us to control it with less force when riding.

We all agree that the Trek Fuel EX excels on downhill and hills, but we don’t think it’s any less suitable for riding on other roads.

For this, we also took to the sand and relatively smooth roads of the sea and found that the Fuel EX 7 2.6” tire size has a strong grip on fine, loose sand and the traction of the front wheels does not slip. The wide size of the tires allows the whole car to float better on the sand. Some people would think, however, that such wide tires would encounter some difficulties on flat roads.

In our review, the EX 7 Trek would indeed be less than excellent in terms of speed, but very strong in terms of stability. Here is our detailed review of the Trek Fuel EX 7’s descents and climbs, key features, components, and specifications, as well as a comparison of its previous versions.

If you prefer exciting descents and exploring uncharted paths, take a look at our review.

I once heard a saying from the old country of the East: “It’s easy to get up the mountain, but hard to get down”. So when we saw the Trek Fuel EX 7, we had a feeling that it would shine in the drop test.

During our 3 month long review, the EX 7 Trek conquered me again and again with its strength. First of all, the road was full of ups and downs and unpredictable conditions, but the EX 7 Trek was able to complete this section without any problems.

The Fuel EX 7 crushes over unavoidable rocks with ease and without making you aware of the obstacle you’ve just encountered. In addition, we encountered unforeseen difficulties during the test, with rain suddenly falling on an apparently sunny day, which made us want to abandon the downhill test on the forest road for a while.

The results really didn’t disappoint me, th Fuel EX 7 didn’t leave us needing great force to keep ourselves and the car close to the ground in the fast descents. This result left everyone but me wide-eyed, and I was actually surprised inside, but I didn’t show it.

In this respect, the performance of the Fuel EX 7 gave me a concrete idea of the value for money compared to the very expensive mountain bikes I have ridden before.

Steep and rugged downhill trails are known to be a great challenge for both the rider and the mountain bike, and we were totally impressed by the downhill appeal of the Fuel EX 7 as it descended over this terrain.

Reasons for Outstanding Performance

Why we would say it performs well, has a lot to do with the configuration of the rear suspension. The Trek Fuel EX 7’s upgraded fork has enough travel to absorb vibrations in the swoop and damp the shock very well.

Not only that, but the vacuum tires, which are wide enough to act as shock absorbers when on sharp and exciting downhill roads. When we encounter larger rocks, the powerful drivetrain takes the rider straight through. When we encounter larger mounds of dirt, the dropper is designed to give us a good rebound and a strong performance in terms of shock absorption.

In sharp turns, the relatively loose head tube angle (66°) will be more stable in the face of steering.

It is also equipped with DebonAir, which not only makes the body lighter, but also acts as a cushion on bumpy paths.

As I tried to create a trail for myself, the components of the EX 7 Trek did the trick, allowing me to experience not only wind-like speed but also a great sense of security as I flew down.

When it came to downhill trips, the Trek Fuel EX 7 excelled and was a great descender.

As we all know from hiking and climbing, we need to have a strong conviction when climbing. I believe the Trek Fuel EX 7 has the same conviction when it comes to climbing. Of course, this is not just wishful thinking on my part, but the vacuum tires on the Fuel EX 7 Bontrager XR4 Team Issue and the set-up of the fork tell the story.

Fire Road Ride

The test was at the place where I live, where there is a fire road leading to the top of a nearby hill. Being on such a road gave me stress. Here I have to admit that I have fallen nose-to-nose many times due to skidding.

This time the Bontrager XR4 Team Issue vacuum tires on the Fuel EX 7 stopped me from being upset about the fire road. There was another rocky section of road to climb on the way to the summit, and the Trek Fuel EX 7’s lightweight body and lockable rear fork allowed us to enjoy the sunset before it was too late.

If you don’t want to get your money’s worth, check out other mountain bikes, but I’d recommend you give the Fuel EX 7 a go.

The Trek Fuel EX 7’s Bontrager XR4 Team Issue tires, with their aggressive appearance, proved to be excellent in loose and rocky conditions. Even on gravel-laden terrain, the large 27.5×2.60′ size and aggressive tread provided agile cornering and plenty of braking power.

Brief Sum-up

When our testers carried out the climbing test, we felt the full traction of the tires. Not only that, but the lockable shock forks make climbing even easier.

It comes with Shimano hubs, and the Rapid Drive 54 hub has the ability to quickly and efficiently convert effort into forwarding momentum. So when the reviewer was on the pedals, the Rapid Drive 54 hub’s timely acceleration function provided a huge boost.

The Trek Fuel EX 7’s SRAM NX Eagle 1×12 drivetrain and a maximum of 50 gears were designed to give us a stable ride on the climbs.

Key Features

What surprised me was the paint color of the Trek Fuel EX 7, which attracted me at first sight. The cool Radioactive Red, and the restrained Dark Prismatic, all caught my fancy.

Also noteworthy is the Control Freak’s cable management, which threads any combination of shift, brake, locking, and drip post cables through the frame for a neat look.

We are also concerned that the EX Fuel 7 has a water bottle mounting hole in the downtube. You may think this is too small, but you may not have noticed that the upper part of the downtube can be opened. You can put some tools and other essentials in there and it doesn’t make the body heavier or less tidy.

Not only that, but the Alpha Platinum Aluminum is light enough and strong enough to provide a powerful ride for climbing. It also allows for agile maneuvering if you encounter an urgent turn.

To be honest, the length of the Trek Fuel EX 7’s compact Effective top tube (size M 60.3) would not allow a tall rider like me to stretch my arms. So, you should always be aware of the size when buying.

However, the Trek Fuel EX 7’s smaller frame (XS and S) has a top tube that tilts down as it approaches the seat tube, which lowers the stand-up height. This helps smaller riders to get on and off the bike and allows them to straddle the bike more easily.

Some people may be concerned that this is detrimental to taller riders, but the Trek Fuel EX takes care of this too. The larger M and above Trek Fuel EX has a straight top tube, which is just as beneficial for those of you with longer legs.

There are many different sizes of Trek EX Fuel 7 mountain bikes, so you can find one that fits your height.

Right off the bat, the Trek Fuel EX 7’s geometry struck me as novel, resembling an obtuse triangular frame. It allowed our reviewer to apply more forceful hand force to the head tube for steering control when descending. Not only that, but the slack seat tube angle (67.5° in M size) will allow you to actively lower the height of your center of gravity when climbing, for better and more stability on climbs.

The looser head tube angle (66.0° in size M) may be perceived as a hindrance to steering, but our review showed that it provides more stable steering in rough and difficult terrain. To complete the picture, we also looked at the length of the Frame reach, 44cm in size M. This shorter Frame reach will allow smaller people to stretch their arms freely, and the air spring design will give cushioning to protect the arms.

The lower BB (max. 34.6 cm) will make the bike more stable by lowering the center of gravity and will give you greater safety on very aggressive descents.

Not only that, but we’ve also looked at the Fuel EX 7 equipped with ABP, which allows you to actively adjust the suspension, meaning you get more agile and reliable control when you hit an obstacle, which is certainly not a novel experience.

Components and Specifications

Sram nx eagle 1 x 12 speed.

The Trek Fuel EX 7 uses the SRAM NX Eagle, a 1×12 speed drivetrain, which gives the Fuel EX 7 a wider range of speeds. Some people think that this is the most entry-level drivetrain for the NX 1×12 and that the 1×12 is heavy compared to the other high end 12 speed SRAM NX Eagle. I don’t think so, and I don’t think that the extra few hundred grams on a full-suspension bike at this level actually has any impact on the overall ride (because of the air fork setup).

Not only that, but the SRAM NX Eagle uses a steel frame for the rear derailleur, although not the high-end carbon and aluminum. However, this does not reduce its durability and is using the same shifting technology, which reduces your difficulties when shifting and allows for smoother shifting.

Shimano RT56, 6-bolt, and SRAM CenterLine, 6-bolt Braking

The Trek Fuel EX 7 uses Shimano RT56, 6-bolt and SRAM CenterLine, 6-bolt brakes on the front and rear wheels respectively, and the dual piston braking equipment will have a more responsive braking ability.

The Trek EX Fuel 7 combines these two brakes, not only to give the Trek Fuel EX 7 smoother braking, which will remain smooth when braking, but also to adapt to braking on all types of terrain.

In addition, this two-piston brake installation is not as difficult as one might expect and can be done quickly.

When I was swooping down from the edge of the road on the Trek Fuel EX 7, the smooth braking of the twin pistons quickly brought me to a halt when I didn’t have time to react to a tight turn on the high-speed descent. I really think it’s going to be one of my favorite mountain bikes.

If you have high standards when it comes to braking your bike, then the price and braking of this bike will successfully catch your eye.

RockShox 35 Gold RL Fork

At this price, the Trek Fuel EX 7 uses a RockShox 35 Gold RL fork. the DebonAir springs are lighter than the others and the Motion Control damping has low-speed compression and adjustable lockout. The fork’s 140mm of travel can be a hindrance to riding on flat roads, but I don’t think this will affect my enjoyment of this value-for-money fork.

Fox Performance Float Shock absorbers

The Trek Fuel EX 7 uses Fox Performance Float shocks. This is a higher priced shock and is very durable. This fork won’t hold you back, it has an internal 3-position DPS damper with 3 adjustments. This makes it possible to deal with a wide range of situations and dampens the shock better. This is really a shining point that makes me happy.

The Trek Fuel EX 7 is equipped with Bontrager XR4 Team Issue vacuum tires, which are available in sizes up to 29”.

The Bontrager XR4 Team Issue will be relatively light in weight with its vacuum tires. The 29×2.60” tire size is suitable for climbing on a wide range of terrain and the 120tpi not only provides plenty of power but is also puncture resistant.

Compared to mountain bikes with fat tires, this one will perform surprisingly well on flat road rides. Its steering traction, when we encounter urgent corners, will provide a great boost.

Trek Fuel EX 7 Previous versions

As you know, the Trek Fuel EX 7 is the upgraded EX series, preceded by the Trek Fuel EX 5. The Trek Fuel EX 7 is slightly more expensive than the Trek Fuel EX 5, but the Trek Fuel EX 7 has upgraded the suspension, drivetrain, and tires to give you a safer and freer ride. If you prefer to spend more time off-road in the mountains and riding on steep descents, I think you could look at the Trek Fuel EX 7.

What do we like about it?

• The full shock absorbers shine when facing downhill.
• Simple and easy to handle dropper that can be modulated for shock absorption when the rider jumps.
• The aluminum frame is not only light in weight but also strong and wear-resistant.
• Multiple sizes, friendly to people with short stature.

What don’t we like about it?

• It would have been better if the operation of the dropper could have been simpler and easier (e.g. electric control), but at this price this is reasonable.
• Some would argue that the SRAM NX Eagle, with its 1×12 drivetrain, would be relatively heavy in terms of weight, but I don’t think the relatively few hundred extra grams would affect the speed of the ride.
• What material is the frame of the Trek Fuel EX 7 made of?

The frame of the Trek Fuel EX 7 is made of Alpha Platinum Aluminium.

• What is the maximum tire size of the Trek Fuel EX 7?

The maximum tire size on the Trek Fuel EX 7 is 29×2.60″.

• What is the drivetrain of the Trek Fuel EX 7?

The drivetrain of the Trek Fuel EX 7 is an SRAM NX Eagle, 1 x 12 speed.

Comparison Table

Trek fuel ex 7 vs norco fluid fs a3.

The two mountain bikes don’t feel very different in terms of their overall design. When I was riding the Norco Fluid FS A3, I noticed that the Norco Fluid FS A3 was bulkier, although it had an outstanding performance on climbs. After this, I found out that the Norco Fluid FS A3 is made of 6061 Alloy, and the platinum aluminum used in the Trek Fuel EX 7 is lighter in weight and very hard-wearing.

Let’s move on to the brakes. The Norco Fluid FS A3 uses the Tektro HD-745 4-piston design, which gives it good performance in terms of braking.

The Norco Fluid FS A3 SRAM SX 1×12 transmission, however, has some difficulties when facing downhill. the SRAM NX Eagle of the Trek Fuel EX 7, with its 1×12 transmission, gives it an excellent performance when facing downhill.

If exciting downhill riding is more your thing, check out the Trek Fuel EX 7.

Trek Fuel EX 7 vs Marin Rift Zone 29″ Carbon 2

I have to say that the Marin Rift Zone 29″ Carbon 2 is a mountain bike with a high-end design. It uses a carbon frame, which is expensive, but that doesn’t detract from my appreciation of the Trek Fuel EX 7.

The Trek Fuel EX 7 uses a platinum aluminum frame, which is relatively inexpensive and you don’t have to worry about its longevity. design for sensitive and stable braking. Its brake lever has an optimized lever shaft position that not only has extra contact points but also matches the habits of most riders.

If you are into rich paint colors, take a look at the Trek Fuel EX 7. I think it is good value for money and the excellent components give the Trek Fuel EX 7 even more capability.

Trek Fuel EX 7 vs Intense Sniper T 29 Expert

The Intense Sniper T 29 Expert is a hardtail bike with an expensive carbon fiber frame, which makes it lighter overall and will make it easier to ride on long trail rides. The dropper and fork are designed to absorb shock. Intense Sniper T 29 Expert is available in two paint colors, and each paint color is a combination of several colors that will be more appealing to youngsters.

To be honest, there is nothing for me to complain about except the price of the Intense Sniper T 29 Expert. For around $1000 the Trek Fuel EX 7 full shock bike gives me a premium experience not only in terms of shock absorption, but also in terms of descending and climbing features. If, for example, you want a good value for money bike, check out the Trek Fuel EX 7.

Trek Fuel EX 7 vs Trek Fuel EX 5

These two bikes from Trek Fuel EX use the same Alpha Platinum Aluminum for the frame and are the same 1×12 shifting, the difference being the Trek Fuel EX 5 Shimano Deore M6100. This drivetrain has a lower rear derailleur and chain tension in lower gears to maintain consistent power even on rough trails.

Of course, we also have to look at the SRAM NX Eagle in the Trek Fuel EX 7. Some people think that the SRAM NX 1×12 will be heavier, but I don’t think this has much of an effect on the Trek Fuel EX 7. On the contrary, the overall weight of the Trek Fuel EX 5 is heavier than the Trek Fuel EX 7.

In terms of components, the Trek Fuel EX 7 has been upgraded. The Trek Fuel EX 7 is more agile than the Trek Fuel EX 5. The Trek Fuel EX 7 has a Knock Block design which protects your head tube if you are making a sharp turn and reduces frictional losses.

As the Trek Fuel EX 5 is not a vacuum tire, it is heavier and the Trek Fuel EX 7 is designed with a vacuum tire, which rolls faster and provides the same great traction on bumpy trails.

The Trek Fuel EX 7 is more expensive due to the cost of the vacuum tire. However, I think this is totally justified as it gives you a more comfortable riding experience.

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.

Trek Fuel EX Vs Top Fuel Similarities

After looking at the things that set Fuel EX and Top Fuel apart, here are some things that the two Trek MTBs have in common.
