/
$3,999.99 Model 30283

While the rest of the industry was mucking about with 29˝ DH bike prototypes for professional mountain bike racers, we brought the party to the people with our first production 29er downhill bike. Session C 29 frameset pairs fast-rolling 29er performance and our proven downhill frame technology. It's long, stable, and aggressive, with a geometry dialed for your fastest runs ever.

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.

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.
