Top Fuel 9.9 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.
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 parts packed with performance advantages.
The tech you get
A light and stiff OCLV Mountain Carbon frame, 130 mm RockShox Pike Ultimate fork with DebonAir spring and Charger 3 RC2 damper, 120 mm of rear travel with a RockShox Deluxe Ultimate RCT shock and SRAM's wireless 12-speed XX AXS direct-mount transmission that's as light as it is precise. Plus, a wide carbon Bontrager Line Elite 30 wheels with a 108-tooth Rapid Drive hub for instant engagement, 4-piston brakes for confident descents, a RockShox Reverb AXS Dropper and carbon handlebar/stem combo.
The final word
The Top Fuel 9.9 is a performance-built carbon rough-terrain bike with top-tier parts that give you noticeable benefits on the trail, like more speed from the carbon wheels, more grip from the ultra-smooth suspension and incredible shifting performance from SRAM's wireless XX AXS transmission.
