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.

The Trek Session has been a staple of the World Cup DH scene and the newest version is one of the biggest updates we’ve seen.

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!

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?
Ultra light and stiff
Exceptional, simple finish
Balanced, aggressive geometry
Quick acceleration and efficient pedaling
Possibly too light and stiff
Top of the line price tag
Lacking traction in rough stuff
Reach may limit taller riders

Sep 2018 · Seb Stott
A pricey bike let down by a basic fork, disappointing brakes and dated geometry
‘ABP’ rear suspension provides a solid, supple action
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

If you're a DH racer, your special edition bike usually comes out during worlds - if you're good enough to qualify and your bike sponsor loves you.

All new carbon framesets for both 27.5 and 29 inch wheels for Trek's downhill race bike

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.

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
