Trek Session 8 29 GX
Details
Session 8 is a downhill mountain bike with a robust alloy frame and high-pivot suspension design that keeps you nimble, planted, and blazing fast on even the most punishing runs.
It's right for you if...
You practically live at the downhill park, and want a fast, traction-packed DH bike that can handle your gnarliest runs thanks to a suspension design that keeps you in control the whole way down.
The tech you get
A burly alloy frame, 200mm rear travel with a FOX DHX shock, 200mm RockShox Boxxer Select with plush Charger RC damper, powerful Code R 4-piston brakes, and a SRAM GX 7-speed drivetrain.
The final word
Session has always been the go-to DH bike. Now it's more of a ripper than ever thanks to new suspension design that delivers more traction, speed, and virtually no pedal kickback.
Why you'll love it
- New suspension layout with a high pivot and idler pulley increases traction, carries more speed, and reduces pedal kickback for more stability
- Virtually zero pedal kickback means you'll stay confidently planted and in control during descents—especially when landing jumps or drops
- The high pivot design delivers a more efficient rearward axle path so you'll carry more speed and your wheel won't get hung up on obstacles
- Adjust your suspension progression by flipping the lower shock mount chip—20% for plush park rides, 25% for racing efficiency
- Our new DH sizing system is based on reach, not rider height, which is the most important factor in a great downhill bike fit
