The EX performs brilliantly on everyday singletrack—the kind of trails you want to ride for hours upon hours. Its handling traits are balanced and nimble, thanks in part to its low bottom bracket and ample standover.

Trek Fuel EX 8 29 review

A cross-country lineage doesn’t hold the Fuel EX back on the trail

Matt Wragg / Immediate Media

Well-specced, fun, agile and responsive trail bike

Heavier or more aggressive riders may want a stiffer fork and more progressive suspension, dropper post isn’t the best out there

The Trek Fuel EX 8 29 is a bike with a lineage going back to cross-country racing. This DNA shines through, but without the drawbacks that this can bring — the Fuel EX is a genuine trail bike.

• Best bike: our buyer's guide to which bicycle type you should buy in 2018
• The Trek Fuel EX 8 29 is one of our Bike of the Year bikes for 2018. To read reviews of the other contenders and the categories tested across road, mountain and women's bikes, visit our Bike of the Year hub .

Trek uses its ABP linkage design on this aluminium frame, with a rear pivot planted around the rear axle. This, combined with the custom RE:aktiv shock delivers a bike that not only climbs well, but can handle the descents too.

The RE:aktiv shock has an inertia valve inside it, which effectively gives an auto on-off pedal platform to prevent the shock from suffering too much influence from pedal inputs, while still remaining active on the descents.

In practice this works well, and it feels like there’s a subtle improvement in feel over some previous generations.

If you mash on the pedals you can definitely get the shock cycling through its stroke — it’s not a lock-out as such (there’s a low-speed compression lever for longer smooth climbs), but on pedally sections the bike feels very calm, composed and efficient.

While older versions had a slight clunk when the platform opened, the current generation is smoother, and there’s less of a noticeable feel when the platform gives way to the bike’s travel.

Once in the travel, the Trek is relatively active, happy to sit into the travel, rather than on top of it. The Fuel EX doesn’t feel super at home on the steepest or roughest of trails, but with a cross-country heritage, this isn't such an issue.

Riders who want to get the most from the bike could add a volume spacer or two to the shock for more progression out of the back end, as the faster and steeper you go, the more the bike likes to find its way to the depths of its travel. It’s here that the bike also feels like it gets knocked around a bit, losing some of that sure-footedness composure it has elsewhere.

However, on the trails it’s most suited to, the ABP suspension does a great job. The rear wheel tracks the ground well, boosting confidence, partly thanks to the fully floating shock that's bolted between the main swingarm and the rocker linkage.

Despite its 14kg weight, it doesn’t feel lardy and it’s happy to be lifted and placed where you want it on the trail. It is, in fact, better suited to a more refined, precise ride, rather than just being pummelled into whatever is in the way — it's a bike that goes fast and rewards riders who are happy to place it where it’s needed.

The frame, combined with the planted feel through the suspension feels like a solid, tight package too. It’s not flexing everywhere, but fortunately avoids feeling harsh, though the front triangle’s stiffness results in a definite accuracy as you guide it through the chop. Thanks to this it’s a fast, stable and fun bike that seems to want to accelerate everywhere.

Through the use of its Mino Link you can change the geometry of the Fuel EX, though I generally kept it in the ‘Low’ setting, best for the 29in wheels.

There’s room for 650b+ wheels in there too, and at this point it might be wise to switch to the high setting to account for the lower ride height given by plus-wheels.

For £2,700 / $3,199 I feel the Fuel EX 8 29 is decent value for money. Trek uses a lot of its in-house Bontrager kit, and generally this is no bad thing.

The Line Comp 30 wheels don’t feel heavy or wooden and the cockpit is a decent shape (though I’d like a slightly wider than 750mm bar). The Line dropper post hasn’t proved the most reliable though, getting a touch sluggish in cold or grimy conditions.

Due to supply issues, the test bike came with Schwalbe Nobby Nic tyres, but Trek lists Bontrager SE5s as the stock tyre. I would like to ride the bike with the Bontrager rubber as the relatively hard compound Nobby Nics on the bike aren’t the grippiest and I feel I could get more out of the bike with slightly better tyres.

Up front is a 130mm Fox Rhythm 34 fork with the Grip damper. This is the base model 34, but one that I'm rarely disappointed to see. Okay, the spring curve from stock is a touch linear, but add a volume spacer or two and it’ll ramp up towards the end of the stroke.

However, the feeling through the bar is smooth and composed, without the slightly harsh or spiky feeling other ‘budget’ forks can have. This year’s Performance and Performance Elite level Fox forks feel better than last year's, but they don’t feel drastically better than the Rhythm 34s here.

SRAM’s Guide R brakes offer decent braking power for a bike such as the Fuel EX, and the GX Eagle groupset now has to be regarded as the benchmark trail groupset.

Trek also offers an XT 2x11 option for the same money in some territories, though I feel the GX Eagle is the one to go for.

2014 Fuel EX 8 29 - Review and Service Questions

• Add to quote

I have same bike, 2014 fuel ex 8 29. Owned for about 1 year, about 800 miles. I had the fork damper unit replaced with fit 2015 as well. I also did seals and gold fluid on the fork. Pretty happy with the fork now, though I am no expert and am not as sensitive to fork performance as some. I also recently (at 600 miles, 200 miles ago) had an issue with the rear triangle in that the rear 12 mm thru axle didn't want to thread in. Upon closer inspection, the rear drop out were out of alignment by some ~.1 inches. Trek store was a good sport and warrantied and that issue is gone. I did notice 2 rides later that one of the rear drop out bearing flanged nut thingy (pardon my French) was loose so I just torqued up with a crescent wrench by hand. NO issues since. I also tacod my front wheel on some brutal trail whoop-d at around miles 250. I am not exactly sure what happened. Result was seriously bent, not quite what I would call a true taco, though so bend I had to kick it to clear fork so I could ride home. Back at home I built some custom clamps from 2x4s and stood on it and brought it back into to round more or less, then trek store adjusted spokes to bring it back into true as much as they could. Nearly true since and no issues. This is the duster of course. I do know the inner wall is visibly rupture din spots but I am not running tubeless and with a bit of rim tape (I use light gauge duct tape) the tubes don't seem to care. All is well there. I also have a slop in the rear wheel axle. Not sure where it is. I recently attempted to tighten brake side lock nuts but I still have a bit of slop. I have ridden that once (today) and now I also have some sort of click/creak coming from the rear of the bike, could be anything, not assuming it is rear wheel related. No big deal. I also recently broke a rear spoke. Replaced myself and one ride on it and it no more broken spokes. Good bike. Main issue with it right now is nothing against the bike really, just that I can't seem to easily prop up front wheel and/or wheelie (though I never have tried prior) and after reading up I suspect the chain stays aren't designed quite as short as they could be. I also have shorter arms for my size which doesn't help. I am looking to do 2016 ex 8 27.5 perhaps. Waste of money really, I probably wont be able to wheelie still. I wouldn't worry about suspension bolts except to keep them tight. Maybe take everything apart and relube rear shock after 2k miles. That is my plan.  

Yeah I noticed it to be a little hard to pull back on, but as you already said, another bike and I still probably couldn't do it well. Yeah the slop in the rear wheel was driving me crazy. I have it sitting in my basement right now and can mimic the play by hand holding each side of the ends. I also think inherently, the 28h duster is probably not the best option for someone who likes to flog the bike and weighs 190-200 geared up. I am also having a creek, and I think it is the BB because it happens mostly when Im standing and crankin up a hill. Im going to stick to my 1000mi teardown/grease plan for the rear suspension/bearings and bottom bracket  

I have the same bike. The only issue I had was I somehow lost the main nut on the main suspension bolt. It's got some huge torque on it too! My torque wrench doesn't go that high! I check all the others frequently now.  

I have the same bike. I like it a lot. Pretty much everything has been upgraded except for the bottom bracket and headset. It's 28 lbs with pedals. The best upgrade has been the Reaktiv shock and Fox 34 fork. The 32 was too noodly for me at 195 pounds. I second the opinion on the wheels. Trek warrantied the wheel set due to the ticking noise as well as the rear hub imploding on me mid ride with a set of Duster Elites. I'm guessing there isn't much difference between the Duster and the Duster Elites, but they are sitting on the shelf anyway. I replaced them with some Easton EC70 trail carbon wheels. Much better! I often wish I would have picked up the Remedy for the additional travel, but every time I get on a grinder of a climb, I am happy to be on the Fuel. It climbs really well, and still handles the descents well enough for me.  

I also thought about the Remedy and may look to go that route next time. I don't NEED the extra travel, but it would definitely be used if I had it. I hear it climbs pretty good with Re:activ. I really like this bike now though, and am looking to probably keep it exactly as is, even the 3x, and hopefully running well. I dont want to put any more money into it because I really want a Carbon HT. I think the creaking BB is the only thing that is not perfect on this bike now and a slight rotor warp in the front. Edit: Was cleaning the bike up and removed the seat post entirely and went to crank it up the hill and "BB" sound is gone.... I guess I need to grease the seatpost. Fuel EX 8 is perfect again.  

I know I'm resurrecting an old thread, but saw this while looking for info on the experience I've had with my Fuel. 2014 Fuel Ex 8 29er. Thank god I bought 3 year red shield. 4 wheel sets now I believe. Broken Evo link. More hubs than I can count. Rear shock went to hell, lost air pressure mid ride and had to be rebuilt. Last fall had chain sag when pedaling backwards. So far they have replaced the wheel, the hub, the axle, the thru-axle, bottom bracket, cassette and derailleur bearings. Still sags. My red shield is up and I'm concerned about the cost of keeping it on the trail. It spends 2 weeks a month at the LBS already. They are going to replace the rear axle nuts (my cost now) so I hope that fixes it but dang.

Apologies for resurrecting an old thread. But I’m looking for the service manual (if it exists) for the 2014 Trek Fuel EX 8 or 9 29er. Bill of materials and exploded view would be ideal. I know these are not readily available to the consumer. Internet search only found the generic trek manual. Sent from my iPhone using Tapatalk

Pinkbike's 2022 Mountain Bike of the Year

"This is a bike that could be used to head out for a big meandering backcountry adventure one day, roll up to the starting line in a local enduro race the next, or even head into the bike park for a lap or three without missing a beat."

Editor's Choice: Best Mid-Travel Trail Bike

"The burliest, most versatile, and most capable Fuel yet; truly up for whatever you want to ride [...] The updated geometry sits comfortably amongst today's best trail bikes [...] Absolutely shreds right out of the box."

"Our favorite Trek"

"Fuel EX proved itself a happy climber. From slabs to roots and square-edge hits, the Fuel EX handled it masterfully. A damn fine trail bike right out of the box, no matter your riding style."

"Fuel EX is a masterpiece"

"Fuel EX absolutely devours chunky terrain while still retaining the ability to tractor up steep climbs. I have become convinced that a bike with long, stable geometry and mid-level travel really can provide the best of both worlds."

Editor's Choice

"The term ‘quiver killer’ may be old and tired, but there’s nothing old-fashioned about a versatile mountain bike that can handle nearly any terrain [...] Riding the Fuel EX this summer was a treat!"

"Loves to ride fast, both up and down"

"Fuel EX is a highly adaptable bike that feels comfortable in a really wide variety of terrain but doesn’t confuse itself for anything more or less. Bike riders, rejoice."

"Ready for anything"

"Fuel EX's geometry feels ready for just about anything. There's plenty of traction for climbing and a nice fluttery feel on descents, calmly smothing out the trail chatter."
