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 down hills. It pairs a SRAM X01 DH drivetrain and Code RSC brakes with our premium OCLV Mountain Carbon frame and RockShox suspension with super-fast 29" wheels.
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.
Why you'll love it
- It's like a precision wrecking ball that gives you the confidence to tear down mountains and take the fastest, burliest lines.
- 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.
- Mino Link and fixed-angle headset cups let you adjust your geometry for the exact handling you want.
