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 with Mino Link adjustable geometry, a 200mm RockShox Boxxer Select fork with plush DebonAir spring, 210mm of rear travel with an adjustable FOX Performance VAN shock, 27.5˝ Bontrager Line DH 30 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.

Features

Alpha Platinum Aluminum

Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.

Integrated frame protection

Integrated guards protect top tube from dual-crown fork stanchion impact, and down tube from trail debris. Down tube guard is removable, allowing riders to shed valuable grams on race day, or to replace the guard as necessary.

Mino Link adjustable geometry

Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.

    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.
