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 new SRAM X01 Eagle drivetrain 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.
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
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.
