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.
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, and want blazing fast wireless electronic shifting.
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 AXS wireless electronic 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 big benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension, and faster, more precise shifts from the AXS drivetrain.
