Details

Top Fuel 9.9 is our top-of-the-line full suspension mountain bike for endurance racers and multi-discipline riders. This down-country rig is built with an OCLV Mountain Carbon frame and spec'd to the hilt with high-performance parts, including a Fox Factory 34 Step-Cast fork, a SRAM XX1 Eagle drivetrain, carbon wheels, and SRAM Level Ultimate brakes. Top Fuel 9.9 flies through singletrack and rips descents, but it really shines when pushed to its full potential during grueling endurance races.
