Feb 2025 · Mike Kazimer

It'll be interesting to see what changes the bike undergoes between the first World Cup DH race in Poland to the last stop at Mont-Sainte Anne - stay tuned for a closer, more in-depth bike check in the future..

Review: Trek Session 9 X01 2022

Oct 2021 · Drew Rohde

If you’re looking for a bad ass downhill bike that will literally have you taking your fingers off the brakes longer as it floats over the chunder beneath you, the 2022 Trek Session 9 is worth a solid look.

Highs
  • Holy Moly Fast!

  • Smooth as butter

  • Fair value

  • Inspires confidence like few others

  • Looks good, paint splatter!

  • G5 Tires

Lows
  • 180mm rear brake rotor

  • Rear end can be awkward, long feeling in tight, slow corners

  • Handlebar sweep/lack of rise
