It's right for you if...
You need speed. You live for it. You dream about it. And when you're on the mountain, you're gonna get after it. You want a faster-rolling 29˝ wheels, a carbon frame, and the latest DH tech out there.
The tech you get
Session 29 is built with an ultralight and ultra-durable OCLV Mountain Carbon, 190mm rear travel with a RockShox Super Deluxe Ultimate DH shock, Carbon Armor, and integrated frame protection like built-in bumpers for a double-crown fork. Plus, it has frame tech that lets you dial your geometry, like Mino Link and the included fixed-angle headset cups.
The final word
This is the fastest downhill bike we make. This 29er-optimized carbon ride is great for rolling over the rough stuff and getting to the finish line with plenty of time to spare.

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.
