Session 8
Trek
Downhill
Session 8 is an alloy downhill mountain bike (2025), from Trek, in the Session series. Rider-wise, it fits a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, while being more at home in gravity-focused bike park riding. Its profile is strongest in areas like capable suspension support for rougher terrain, a balanced ride feel between comfort and directness, and good fit flexibility for dialing in rider position. The main trade-off is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
