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 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.

"Racing blood, trail spirit"
"It's devilishly quick, accelerates in a way that makes it seem like my legs actually produce real power. It's stable, planted, and it tracks like it's supposed to. Endurance athletes will be able to remain seated over more terrain, saving precious energy over the long haul, while XC pinners will hook up better on steep technical climbs."Read more
"Super light and fast as hell"
"The new Top Fuel might not be a pure XC-race bike anymore, but it's still precise and very fast. Its new trail orientation makes it a great choice for a rider who wants a fast and light bike with most of the the efficiency of a cross-country race bike, but with bit more versatility and playfulness."Read more

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.
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.
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 setup.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
