Session C 27.5 frameset is an agile carbon DH mountain bike that's built for tearing up the biggest descents. Strong and light OCLV Mountain Carbon tubes, 190mm of travel with a FOX Factory shock, and the best frame tech make it the perfect platform for downhill speed.

• 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
• OCLV Mountain Carbon is light and strong, even on the wildest runs
• Race or get rowdy? This bike does both
• 27.5 wheels are great for flicking the bike around through the most technical trail
• Mino Link and fixed-angle headset cups let you adjust your geometry for the exact handling you want

Active Braking Pivot

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.

OCLV Mountain Carbon

Trek's mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.

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.
