Fuel EX 9.9 makes no compromises. A carbon frame, carbon wheels, a Shimano XTR 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 Shimano XTR drivetrain. Plus, powerful Shimano XTR 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 lets you securely stow ride essentials and doesn't detract from the bike's 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" wheels, S frames get to choose between 27.5" or 29", and sizes M to XL get 29" wheels
- Make it yours: it's fully customizable through Project One

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.
