Field Test Review: 2024 Trek Slash - Rides Like a Session

Oct 2023 · Dario DiGiulio

Trek did a very good job making the Slash a quiet bike, then seemingly lost the plot when they specced a hard rubber chainslap protector that does little to mitigate the drivetrain noise in bumpy terrain.

Highs
  • Excellent geometry and balanced ride

  • Composed, capable, and predictable suspension

  • Climbs well for such a downhill-focused bike

  • Excels in challenging terrain

Lows
  • Chassis may be too stiff for some

  • Chain drop issues due to improperly spaced lower idler (fixed)

  • Stock chainstay protector did very little to manage noise

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
