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 going to chase after it. You want 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, 190 mm rear travel with a FOX Factory X2 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-optimised carbon ride is great for rolling over the rough stuff and getting to the finish line with plenty of time to spare.

favorite_borderWhy you'll love it
- We put a whole lot into this bike, including nearly a decade of research and development by engineers and designers who wanted to break the mould of DH capability and speed – and they succeeded
- Session 29 is taking downhill to a new place, and it's leading the charge on the World Cup circuit among the very first 29er DH bikes
- The fastest runs demand the most dialled set-up: the air shock and fork on Session 9.9 are adjustable and easy to fine-tune for different tracks
- Mino Link and fixed-angle headset cups let you adjust your geometry for your personal handling requirements
Features
ABP
Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time.

Integrated frame protection
Integrated guards protect top tube from dual-crown fork stanchion impact, and down tube from trail debris. The 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.
