Overview
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.
Why you'll love it
- You care about the finer things in life, like silky-smooth suspension that feels greater than the sum of its numbers, and fully wireless shifting that keep your setup tidy and low maintenance
- You can tackle any trail on the mountain with its progressive geometry that makes light work of steep, punchy climbs, and turns around to rally the descents
- It comes with light and stiff carbon wheels that make quick work of technical terrain and keep you on your line, even when things get hairy
- We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels
- With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
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."

"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."
