The Beta Tests: Trek Slash 9.8

Mar 2021 · Lydia Tanner

The Trek Slash has been 29-inch-only since 2016, and the 2021 version is evidence of its head start in the big-wheel enduro category.

Highs
  • Superb high-speed stability

  • Great traction in variable terrain

  • Supple and generous-feeling suspension

Lows
  • Less maneuverable at slow speeds

  • A lot of bike to get back up the hill
