Trek Session 8 Full Suspension Mountain Bike 2025
Trek Session 8 Full Suspension Mountain Bike 2025
The Session 8 is a downhill mountain bike with a burly 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 all the way down.
The tech you get
A burly alloy frame, 200 mm rear travel with a Marzocchi Bomber shock, 200 mm RockShox Boxxer Select with plush Charger RC damper, powerful Code R 4-piston brakes and a SRAM GX 7-speed drivetrain.
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 that 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
The final word
The Session has always been the go-to DH bike. Now it's more of a ripper than ever thanks to a new suspension design that delivers more traction, speed and virtually no pedal kickback.
