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.
  • 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 mold 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
  • 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.
