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

High-class fitness bike with proven road technology and a classy component package. Buy if you want a capable, high-spec yet sensible-handling bike with a flat bar

Highs
  • Comfortable-yet-fun ride, IsoSpeed decoupler, lightweight, Shimano 105

Lows
  • Cost is the biggest one, funky-looking grips, only available in black
