Manufacturer Description

Session 9.9 is the pinnacle of downhill mountain bike performance. This is the same DH bike the pros ride, and it's built for one reason: going as fast as freakin' possible downhill. It pairs a SRAM X01 DH drivetrain and Code RSC brakes with our premium OCLV Mountain Carbon frame and top-shelf RockShox suspension.
