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 Trek's premium OCLV Mountain Carbon frame and FOX Factory suspension with super-fast 29-inch wheels. This is the same DH bike the pros ride, and the bike of choice for World Champion Gee Atherton.
It's right for you if...
You want the fastest downhill bike Trek offers. You want the speed of 29-inch wheels and the stability of a full-on DH frame. You seek out the fastest lines, and the biggest jumps. You like to dial in your ride, and want the ability to fine-tune your suspension, fit, and handling on a bike that makes no compromises.
The tech you get
An OCLV Mountain Carbon frame, 190mm tunable front and rear FOX Factory air suspension, Bontrager Line DH wheels, and proven Shimano Saint drivetrain and brakes. This is a full-on DH race bike, and it's built so you can refine your setup for your fastest runs with Mino Link and an adjustable fixed-angle headset.
The final word
Best frame, best suspension, best parts, and fast-rolling 29-inch wheels. This is the only choice if you're a true DH devotee. Session 9.9 is simply the fastest bike on the mountain, even when that mountain is a stop on the World Cup circuit.
Why you'll love it
1 - It's like a precision wrecking ball that gives you the confidence to tear down mountains and take the fastest, burliest lines
2 - The fastest runs demand the most dialed setup: the air shock and fork on Session 9.9 are adjustable and easy to fine-tune for different tracks
3 - Mino Link and fixed-angle headset cups let you adjust your geometry for the exact handling you want
