2020 TREK SESSION 9.9 MOUNTAIN BIKE
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.
