Summary

The Trek Session is a downhill bike known for its American-made frame and high-quality construction, offering 190mm of travel with a trunion mount Float X2 suspension. It's available in both 27.5 and 29er versions, featuring a stiffer and longer design that's described as a 'terrain eating beast'. While it boasts a high-end build and performance, it comes at a higher price point compared to Asian-made frames.

Review: Trek Session 9.9 29

nov 2018 · Drew Rohde

A review worth reading if you are considering a 29er DH bike. The Trek Session 9.9 downhill bike has a couple interesting quirks but is without a doubt one of the best DH bikes we've ridden in. If you're a racer looking for pick up speed and drop seconds, check this bike out!

Review: Trek Session 9.9 29

oct 2018 · Paul Aston

One of the most successful, recognizable silhouettes on the DH circuit now comes with wagon wheels. So how does it compare to the newest crop of DH bikes?

Highs
  • Ultra light and stiff

  • Exceptional, simple finish

  • Balanced, aggressive geometry

  • Quick acceleration and efficient pedaling

Lows
  • Possibly too light and stiff

  • Top of the line price tag

  • Lacking traction in rough stuff

  • Reach may limit taller riders

Trek Session 8 27.5 review

sept 2018 · Seb Stott

A pricey bike let down by a basic fork, disappointing brakes and dated geometry

Highs
  • ‘ABP’ rear suspension provides a solid, supple action

Lows
  • Relatively short front end feels cramped, high bottom bracket and short frame deliver a sometimes precarious-feeling ride, harsh fork and weak brakes are disappointing for the price

First Look: 2018 Trek Session 29 and 27.5

may 2017

Trek releases the 2018 Session with updated geometry, refined linkage, and a revamped Float X2 shock. There's also a 29 inch version, which the internet will probably have nothing to say about.

may 2017 · Francis Cebedo

Trek’s pursuit of downhill speed has led to a longer, stiffer, Session. A 29er version has been added as well to now that components have caught up with the demands of the big wheel. - Mtbr.com
