[R]eviewed // Trek Fuel EX

Jun 2023 · Scotty Prendergast

Field Test: Trek Fuel EX - Evolution Underlined

Dec 2022 · Mike Levy

The downtube storage compartment is on the new bike, and while it seems like Trek has put all the things onto the latest Fuel EX, there's one that they didn't: Knock Block.

Highs
  • Wide range of effective geometry adjustments

  • Just as much fun on smooth trails as it is on scary trails

  • Great climber, efficient pedaling

Lows
  • One-piece handlebar might be too stiff for some riders

  • Paint chips easily
