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, 120 mm RockShox SID Select+ fork, 120 mm of rear travel with a RockShox SID Luxe Ultimate shock and a new Shimano XT 1x12 drivetrain. Plus, wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, 4-piston brakes for confident descents, 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 tyre 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 set-up 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.
