Session 8 Wild Mushroom

Detail Information

The Trek Session 8 in Wild Mushroom is purpose-built for riders chasing podiums, bike park laps and the steepest downhill trails imaginable. Developed for gravity riders who demand speed, control and confidence, the Session 8 combines race-proven suspension technology with durable components to tackle the most demanding terrain.

At its core is Trek's robust Alpha Platinum Aluminum frame, engineered to withstand the punishment of downhill racing while delivering impressive stiffness and durability. The advanced high-pivot suspension design provides 200mm of rear wheel travel, allowing the rear axle to move rearward through impacts for improved momentum, increased traction and greater composure through rock gardens, roots and braking bumps.

Up front, the legendary RockShox Boxxer Select dual-crown fork delivers 200mm of plush travel, absorbing the biggest hits with precision and confidence. Paired with a Marzocchi Bomber rear shock, the suspension package provides exceptional stability, grip and control on technical descents.

When speed needs to be scrubbed, SRAM Maven Bronze hydraulic disc brakes deliver massive stopping power with outstanding modulation, giving riders confidence to brake later and ride faster. The dedicated SRAM GX DH 7-speed drivetrain offers close-ratio gearing optimised for gravity racing, ensuring fast, reliable shifts under the toughest conditions.

Designed around modern downhill geometry, the Session 8 inspires confidence at race pace while remaining agile through tight corners and technical sections. Finished in the distinctive Wild Mushroom colourway, it stands out just as much in the lift line as it does on the podium.

Whether you're racing downhill, riding shuttle laps or spending weekends in the bike park, the Trek Session 8 is engineered to help you ride faster, smoother and with total confidence.
