It's right for you if...
You want the fastest downhill bike we offer. You want the speed of 29˝ 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
A full OCLV Mountain Carbon frame, 190mm RockShox Boxxer Ultimate fork with plush DebonAir spring, 190mm of rear travel with a RockShox Super Deluxe Ultimate DH shock, 29er Bontrager Line DH 30 wheels, SRAM X01 DH drivetrain, SRAM Code RSC brakes, and a Bontrager Line Pro OCLV carbon handlebar. 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˝ 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.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
