Trek FX 2 Disc Equipped review: Unspectacular but effective

Sep 2022 · Benjamin Page

The Trek FX 2 Disc is a versatile all-rounder with surprising levels of comfort and stability

Highs
  • The frame has a great balance between responsiveness and comfort

  • Equipped for night riding, bikepacking or commuting

  • Can carry a decent amount of weight

  • Stable ride for long distances

Lows
  • Would need a drivetrain upgrade to become a serious fitness bike

  • On the heavy side for a rigid frame
