Trek Session 8 29 Gx Mountain Bike
All speed, no hang-ups
Session’s high-pivot design results in a rearward axle path that lets the back wheel move with the rearward force from bumps, not against it. On the trail, it feels like smoother suspension that maintains more forward momentum and provides more grip.
Rock the mullet
Session comes stocked for speed with 29er wheels, but party-in-the-back riders can run a mixed set up with a 27.5˝ rear wheel, or even 27.5″ front and rear for more agility.
Tune for your trail
With Mino Link adjustments on both geometry and suspension, you can easily tune your Session to a progressive feel for racing days or dial it back for park days.
Reach-based sizing
When it comes to DH bikes, your reach affects your fit and ride quality far more than seat tube length. We’ve based Session’s sizing on reach to ensure you can find the set up that’s right for you.
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.
Size-specific chainstay length
The chainstay length, or rear center, grows as the frame reach grows so you get balanced weight distribution no matter your frame’s size. High-speed control and big mountain fun for everyone.
