Details
Top Fuel 9.9 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents. It gives you the confidence you want through roots and rocks thanks to a 120mm/130mm (rear/front) RockShox suspension package with a Pike Ultimate fork and Deluxe Ultimate shock.

You like to ride everything – long alpine climbs, rooty aspen slalom, fast XC singletrack, and you want a bike that can keep up on the ups and hold its own on the downs. Keeping things light is critical, so you want a carbon frame and the cream of the crop parts, like an all-new, ultra-smooth Shimano XTR Di2 drivetrain.

Shimano's all-new XTR Di2 12-speed drivetrain, Shimano XTR M9220 hydraulic brakes, Bontrager Line dropper post, and tubeless-ready Bontrager Line Pro 30 OCLV Carbon wheels.
