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 component package with a low-weight carbon frame for one unbelievably fun rig that's fast on flow and fun to ride on techy singletrack.

- Wider Line Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- Bontrager DropLock's shifter-style lever lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiency. Plus, it controls your dropper post too
- This bike’s killer suspension setup is both efficient and ready to party
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
