It's right for you if...
You have refined taste in mountain bikes, and don't like to settle. You want a bike built to tackle the whole mountain and rule it all with the finest technology the bike industry has to offer, from its light and stiff carbon frame and wheels that track through the hairiest lines, to the FOX Factory fork and fully wireless SRAM XX1 top-tier groupset.
The tech you get
A featherweight OCLV Mountain Carbon frame built to handle the rough and rowdy, a pair of finely laced carbon wheels that track through technical terrain with ease, and SRAM's top-tier XX1 AXS fully wireless electronic drivetrain. Plus, you get the silky smooth travel of a 150mm FOX Factory 36 Fork with EVOL air spring and GRIP2 damper and 140mm of FOX Factory Float rear suspension with 2-position damper, all topped off with adjustable geometry for fine-tuning your ride to you and internal frame storage that lets you keep your setup tidy without leaving behind trail essentials.
The final word
Fuel EX 9.9 is a bike built to satisfy those with the finest taste. It pairs together an all- mountain trail capable carbon frame with the finest components you'll find on a modern mountain bike, from its carbon hoops to wireless SRAM XX1 AXS shifting. It's all wrapped up with adjustable geometry, so you can fine tune your ride to always feel how you want it.

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."

"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."

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Slack or steep, the choice is yours
Install angle adjust headset cups (sold separately) to tweak the 64.5-degree head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.
Adjust the sus for full send
Adjust leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock.
Size-specific stays
Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.
Business in the front, party in the back
Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a 160mm fork, and get ready to party.
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
New frame, new possibilities
Forward-thinking frame design opens possibilities for riders who want full customization. A bigger seat tube lets you roll with a beefier, longer dropper post, and broader shock compatibility plays well with tons of aftermarket shocks, including coil.
Need an adjustment?
Make your head tube angle slacker or steeper by one degree with angle-adjust cups.
