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.

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.

A light and stiff full carbon frame, 120 mm Fox Factory 34 Step-Cast fork, 115 mm of rear travel with a Fox Factory Float shock and a new SRAM X01 Eagle drive train with an extra-low 52-tooth climbing gear. 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.

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.
- It's the ultimate down-country bike - light, capable and trimmed with high-performance components
- Wider Kovee Pro 30 wheels provide better tyre 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 set-up reminiscent of the all-mighty mullet - it's both efficient and ready to party
- Make it yours: it's fully customisable through Project One

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. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.

Rapid Drive 108 rear hub
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
