It's right for you if...
You want an efficient, capable, short-travel trail bike that excels at endurance and stage racing and can handle rough trails and even XC races. You appreciate the performance advantage of carbon and want a super-light bike with race-level components and suspension.
The tech you get
A full OCLV Mountain Carbon frame, upgraded 120 mm Fox Performance 34 Step-Cast Float fork with GRIP damper, 115 mm of rear travel with a Fox Performance Float shock and a 1x12 SRAM GX Eagle drivetrain with Truvativ Descendant 7k DUB cranks. Plus, wide carbon Bontrager Kovee Elite 30 wheels with a 54-tooth Rapid Drive hub for fast engagement, TwistLoc dual remote suspension lockout, Bontrager Line Elite Dropper, Bontrager Kovee Pro OCLV Carbon handlebars and upgraded Shimano SLX hydraulic disc brakes.
The final word
Top Fuel 9.8 is an efficient, capable and ridiculously fun short-travel carbon trail bike with the performance boost of upgraded parts like the drivetrain, fork and brakes. It's built to rip technical terrain and descents, speed through flow sections and withstand the beating that endurance races dole out.

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.
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.
TwistLoc Dual Remote Lockout
TwistLoc simultaneously locks out front and rear shocks with a simple Grip Shift-like motion; and it leaves room for a dropper post lever.

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.
