Add a note to encourage purchase
The Session 9.9 is the pinnacle of downhill mountain bike performance. It's built for one reason: going as fast as freakin' possible down hills. It pairs proven Shimano Saint parts with our premium OCLV Mountain Carbon frame and FOX Factory suspension. This is the same DH bike the pros ride, and the bike of choice for World Champion Rachel Atherton.
