Top Fuel 9.9 is a top-shelf full suspension mountain bike for riders who are serious about their fun. Its lightweight carbon frame is spec'd to the hilt with high-end suspension and high-performance parts. And all those fancy bits and bobs are really, really good at hitting the party line.

It's right for you if...
You're looking for the fastest way to a good time on the trail, and you're willing to crack open the piggy bank for top-shelf suspension and lots of lightweight carbon.

The tech you get
A light and stiff full carbon frame, 120mm Fox Factory 34 Step-Cast fork, 115mm of rear travel with a Fox Factory Float shock, and a Shimano XTR 1x12 drivetrain. Plus, wide carbon Bontrager Kovee Pro 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, Bontrager DropLock dual remote suspension lockout, and lots of carbon everywhere.

The final word
With Top Fuel 9.9, you get a smooth, fast ride that doesn't shy away from rowdy trails. An OCLV Mountain Carbon frame, top-of-the-line suspension, and carbon components join forces for a nimble and insanely fun ride.

Why you'll love it
- It’s the ultimate down-country bike—light, capable, and trimmed with high-performance components
- Wider Kovee Pro 30 wheels provide better tire support so you can run lower pressure and get more traction
- Bontrager DropLock's shifter-style lever lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiently. Plus, it controls your dropper post too
- This short-travel bike has a killer suspension setup reminiscent of the all-mighty mullet—it's both efficient and ready to party
- 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 (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.
