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, 120 mm Fox Factory 34 Step-Cast fork, 115 mm of rear travel with a Fox Factory Float shock and a Shimano XTR 1x12 drive train. 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.

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.
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.
Bontrager DropLock Lever
One easy-to-use lever locks out your suspension and controls your dropper post with no unnecessary handlebar clutter.
Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
