It's right for you if...
You're a regular on the lifts and at the bike park. You're looking for a playful, versatile, durable DH rig with proven performance and a park-ready geometry, and want a lot of tech for your money.
The tech you get
An Alpha Platinum Aluminum frame, 200mm/210mm RockShox front and rear suspension with an adjustable air fork, Bontrager Line DH wheels, SRAM Guide R brakes, and a DH-specific SRAM GX 7-speed drivetrain. Race, rip, ride. This bike does it all.
The final word
Fast, durable, agile, and stable. Session 8 is fully capable of taking on the gnarliest descents, the biggest jumps, and the burliest trails. It's a versatile, confidence-inspiring ride with the best in DH tech and a geometry that's not so low and long that it doesn't play nice at the park.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
