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 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, 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.

Why you'll love it
- 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
- 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
