Fuel EX 9.9 makes no compromises. A carbon frame, carbon wheels, SRAM's X01 Eagle 1x12 drivetrain, and FOX Factory Float suspension make this the one carbon full suspension mountain bike that rules every trail. It's fast on singletrack, light on climbs, and stable through the rowdiest terrain you can find.
It's right for you if...
You're a mountain biker through and through, and want a single carbon bike for the best performance on everything from marathon races to gnarly descents and technical trail. You know you'll be riding this bike on every trail, so you're not going to compromise on frame material, suspension, or components.
The tech you get
A light and stiff full OCLV Mountain Carbon frame, 140mm FOX Factory 36 Float fork with GRIP2 damper, 130mm of rear travel with a FOX Factory Float shock featuring Trek's exclusive RE:aktiv with Thru Shaft, and a 1x12 SRAM X01 Eagle drivetrain. Plus, powerful Shimano XT 4-piston hydraulic disc brakes, Tubeless Ready Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive rear hub for quick engagement, a Bontrager Line Elite dropper post, and a Bontrager Line Pro OCLV Carbon handlebar. An internal storage compartment and Control Freak cable routing add to the bike's capability and sleek look.
The final word
If you can have just one mountain bike, this is it. Fuel EX 9.9 has the highest-end parts on the best OCLV Mountain Carbon frame we make. It's equally at home on fast singletrack, gnarly trail, and laying down miles on your next multi-stage race.
Why you'll love it
- Fuel EX 9.9 is the single best choice for riders who want an all-mountain ripper that excels at everything from marathon races to burly technical terrain to singletrack
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5-inch wheels, S frames get to choose between 27.5-inch or 29-inch, and sizes M to XL get 29-inch wheels
- Make it yours: it's fully customizable through Project One
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
