Top Fuel 9.8 is a full suspension carbon mountain bike for riders who dont settle. Not for parts nor for one style of riding. It combines a high-end components package–including a SRAM GX Eagle AXS wireless electronic transmission–with a low-weight carbon frame for one unbelievably fun rig thats fast on flow and fun to ride on techy singletrack.
  • You get clean shifts, even under load, with SRAMs smart, smooth, and completely wireless GX Eagle AXS transmission
  • A sleek internal storage compartment gives you a versatile spot to stow tools and gear
  • Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
  • This bike’s killer suspension setup is both efficient and ready to party
  • Wider Line Elite 30 wheels provide better tire support so you can run lower pressure and get more traction

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.

Quick and in control

120mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.

Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

Hassle-free routing

Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.

Will my bike have a curved top tube?

Smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically dont have the same issues with standover height.

You almost forgot your pedals

This bike doesn’t come with pedals because youll have a better ride if you choose your own. Explore the pedal guide to find the best pedals for your riding style. Reach for flat pedals for simple versatility or go for clipless MTB pedals if you want control & efficiency.
