Details

Fuel EX 9.9 makes no compromises. Top-shelf suspension, carbon everything, and a super-smooth Shimano XTR drivetrain make this ripper ready to rule any trail in style. It's fast, it's light, and it's got everything you need to crush your next trail ride.

It's right for you if...
You want a bike as versatile as you are, and you're demanding—of yourself and of your equipment. You want the lightest weight, the most adjustability, and the highest precision so the last thing you have to worry about on your next adventure is your bike.

The tech you get
A light and stiff OCLV Mountain Carbon frame with internal storage, FOX Factory suspension with Kashima Coat and an efficient yet plush RE:aktiv with Thru Shaft damper. A Shimano XT 1x12 drivetrain for super-smooth shifting that's easy on the thumb—plus an extra-low 51-tooth climbing gear, and Bontrager carbon wheels and a whole bunch of other carbon parts for lower weight and elevated good looks.

The final word
If you can have just one mountain bike, this is it. Fuel EX 9.9 has the lightest parts with the most adjustability and precision. It's equally at home on fast flowy singletrack, brutal leg-busting climbs, and gnarly arm-pumping descents.

Why you'll love it
- Fuel EX 9.9 is for riders who want the best in everything. It's dripping with carbon and has the latest in suspension and drivetrain tech
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- The Fox Factory 36 fork gives you four-way damping adjustments, plus you get Kashima Coat for smoother, more durable stanchions
- 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

Dropper posts

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.

Will my bike have a curved top tube?

Will my bike have a curved top tube?

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.
