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 drive train and Code RSC brakes with our premium OCLV Mountain Carbon frame and top-shelf RockShox suspension.

You want our fastest downhill bike, with 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.

A full OCLV Mountain Carbon frame, 190mm RockShox Boxxer Ultimate fork with a plush DebonAir spring for better small bump compliance, 190 mm of rear travel with a RockShox Super Deluxe Ultimate DH shock, 29er Bontrager Line DH 30 wheels, SRAM X01 DH drive train, SRAM Code RSC brakes and a Bontrager Line Pro OCLV carbon handlebar.

Best frame, best suspension, best parts and fast-rolling 29? wheels. Session 9.9 is the fastest bike on the mountain, even when that mountain is a stop on the World Cup circuit.
- It's like a precision wrecking ball that lives for tearing down mountains and taking the fastest, burliest lines
- The fastest runs demand the most dialled set-up: 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 your personal handling requirements

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.



OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.



Looks like a World Championship
Trek Factory Racing's Reece Wilson charged his way into the rainbow jersey aboard Session this year, taking all the right risks on a slick course and carving his name in Downhill's history books with a truly gutsy run.
