With the supremacy to keep firing at full gas all the way down your run, the Trek Session C 27.5 Mountain Bike Frameset is the perfect choice for discerning riders yearning for greater control and speed on fresh, loamy tracks.

The low weight frame and Fox Factory Float X2 rear shock work together to keep your rear end pinned and front end responsive, nimble and snappy, so you can finally sit at the bottom of the trail and wait for your friends like a true pro.

Trek Session C 27.5 Mountain Bike Frameset 2021

If Rachel Atherton or Gee Atherton is anything to go by, the Trek Session C 27.5 Mountain Bike Frameset is a fully-fledged trail shredder ready to take your ride control, handling and ultimately, speed to new heights. Everything about this frameset is designed to keep you pinned, firing at full gas and assuring you of supremacy when you check out your times down the run.

The frame is constructed from Trek’s OCLV Mountain Carbon, keeping the overall weight insanely low and letting you handle a bike as you want it to handle: snappy, responsive and agile. The E2 tapered head tube furthers durability of the front end and stops any flex in the front, whilst a down tube guard reduces rock strike damage when you’re pounding over rock gardens at full gas. Designed solely for downhill use only, the geometry of the Session is entirely developed for stability and handling, allowing you to rip into the corners and send huge jumps with more confidence than you ever thought imaginable.

With this in mind, a 210mm front fork is an ideal choice for the Session C 27.5, giving impressive impact absorption and keeping your front end in check. Stopping the rear from bouncing around like a rabbit on steroids, Trek has introduced a Fox Factory Float rear shock. Tuned by the Trek Suspension Lab, this shock features externally adjustable rebound and low-speed compression, meaning you can perfect your ride to your preferences and shred the trails with full knowledge your bike is built to do the job.


  • Longer, more aggressive geometry keeps you attacking the whole way down
  • OCLV Mountain Carbon with Carbon Armor is downhill tough
  • Fine-tune your ride with Mino Link and an all-new adjustable headset system
  • Fast 27.5˝ wheels get you down the mountain first
