It's right for you if...
You're looking to build a rugged DH or park bike for the biggest trails out there, and want a 27.5˝-optimised frameset with exclusive trail tech, like adjustable Mino Link geometry, which can't be found anywhere else.
The tech you get
A burly Alpha Platinum Aluminium frame with 210 mm of travel with an adjustable FOX Performance VAN shock, integrated frame protection, FSA Orbit headset and exclusive trail tech like ABP and Mino Link. Built for 27.5˝ wheels.
The final word
This burly frame set is perfectly capable of taking on the roughest, fastest descents you can find, and it's equally at home in the park, too. The best DH frame tech, a stable geometry and a quality shock give you a head start on your dream downhill rig.

favorite_borderWhy you'll love it
- Session has the heart of a monster truck: it rolls over everything, gives you the confidence to take on rougher trails, and saves you when you don't take the right line
- Quality FOX Performance suspension and our ABP frame design keep you in control
- Race or get rowdy? This bike does both
- 27.5 wheels are great for flicking the bike around through the most technical trails
- Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
Features
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Looks like a World Championship
Trek Factory Racing's Reece Wilson charged his way into the rainbow jersey aboard Session this year, taking all the right risks on a slick course and carving his name in Downhill's history books with a truly gutsy run.
