Details

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 parts package—including a new SRAM GX Eagle AXS wireless electronic drivetrain—with a low-weight carbon frame for one unbelievably fun rig that's fast on flow and fun to ride on techy singletrack.

- The SRAM GX Eagle AXS drivetrain is smart, smooth, and completely wireless
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- 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
