Top Fuel 9.8 is a full suspension carbon mountain bike for riders who don't 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 that's fast on flow and fun to ride on techy singletrack. 

It's right for you if...

You’re looking for a do-it-all full-suspension mountain bike that's efficient and fast, but doesn't shy away from some bigger stuff. You want the added stiffness and weight savings of a carbon frame, and want blazing-fast wireless electronic shifting.

The tech you get

A light and stiff full carbon frame, 130 mm RockShox Pike Select+ fork, 120 mm of rear travel with a RockShox Deluxe Ultimate RCT shock and a SRAM GX Eagle AXS wireless electronic transmission with an extra-low 52-tooth climbing gear. Plus, wide Bontrager Line Elite 30 carbon wheels with a 108-tooth Rapid Drive hub for instant engagement, Bontrager Line Elite Dropper and Bontrager RSL integrated carbon bar/stem combo.

The final word

The Top Fuel 9.8 is a ridiculously fun carbon down-country bike with upgraded parts that give you big benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension, and faster, more precise shifts from the AXS transmission.

Why you'll love it

  1. You get clean shifts, even under load, with SRAM's smart, smooth and completely wireless GX Eagle AXS transmission
  2. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
  3. Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
  4. This bike’s killer suspension set-up is both efficient and ready to party
  5. Wider Line Elite 30 wheels provide better tyre support so you can run lower pressure and get more traction
