Equipped with a SRAM X01 DH drive train and Code RSC brakes, it also boasts a premium OCLV Mountain Carbon frame, ensuring unparalleled durability and response on the trails.

This bike is perfect if you're a thrill-seeker chasing the fastest downhill stretches and gravity-defying jumps. The Session 9.9 29 offers phenomenal customisation potential, with the ability to fine-tune your suspension, fit and handling on a ride that makes no compromises.

The rock-solid build features a full OCLV Mountain Carbon frame, a 190mm RockShox Boxxer Ultimate fork with a plushy DebonAir spring for increased small bump compliance, and rear travel assisted by a RockShox Super Deluxe Ultimate DH shock. Reliable Bontrager Line DH 30 wheels keep you grounded when it matters most, complemented by a speedy SRAM X01 DH drive train and precise SRAM Code RSC brakes. And when it comes to control, nothing beats the Bontrager Line Pro OCLV carbon handlebar.

The Session 9.9 29 is built for ultimate speed, even on World Cup circuit stops. Dive into the roughest terrain and most challenging lines with confidence, as you wield a precision wrecking ball that loves tearing down mountains. And with adjustable air shocks and a dial-in set option for different tracks, you can tailor every ride for maximum performance.

Ample control accompanies killer speed thanks to the innovative Active Braking Pivot (ABP), uniquely tuned to manage accelerating and braking forces separately, for a riding experience that enhances command and confidence.

The OCLV Mountain Carbon represents TREK's stand-out, mountain-specific carbon fibre toughness. With unique materials and lay-up procedures underlined by advanced engineering, this is a bike that more than meets the rigorous demands of downhill racing.
