Field Test Review: 2025 Specialized Stumpjumper 15 Alloy

Nov 2024 · Dario DiGiulio

The alloy Stumpy packs a punch for the price, and you can run a cable-actuated derailleur.

Highs
  • Suspension is impressively sensitive

  • Extensive adjustment to alter geometry, wheel size, and shock performance

  • Can descend like a bigger bike

Lows
  • Quite heavy for a trail bike, due primarily to frame weight

  • Genie shock warrants extended setup testing

  • Can be hard to balance sensitivity and support
