Top Fuel 9.8 is a full-suspension carbon mountain bike for riders who don't settle for one style of riding.

It combines a high-end parts package—including a 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.

Why you'll love it

  1. Wider Line Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
  2. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
  3. This bike’s killer suspension setup is both efficient and ready to party
  4. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius

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, but don't mind saving some money on the parts.

The tech you get

A light and stiff full carbon frame, 120mm RockShox SID Select+ fork, 120mm of rear travel with a SID Luxe shock, and a SRAM GX Eagle drivetrain with an extra-low 52-tooth climbing gear. Plus, wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, Bontrager Line Elite Dropper, and carbon handlebars.

The final word

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

Sizing & Fit

This Medium frame generally fits riders 5'4"-5'9", but there are some other factors, like arm and leg length, that determine a great fit.
