Stumpjumper 15 Alloy is here to obliterate every trade-off in the trail game.

Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you? Check, check, check.

The biggest innovation on the Stumpjumper 15 Alloy is GENIE. This patent-pending air spring technology grants every trail rider three wishes: the maximum grip and traction of a coil spring feel, better bottom-out prevention than a standard air spring, and the ability to tune mid-stroke and end-stroke support independently.

With 16.3% better bump force management than a traditional air-sprung shock, GENIE makes the Stumpjumper 15 Alloy ride like a bike with more travel. Extensive field testing proves that Stumpjumper 15 Alloy with GENIE delivers 57% better traction than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance.

Features:

  • GENIE Shock Technology for a playful ride with a bottomless DH feel.
  • Six-way geometry adjustment for unmatched personalization.
  • 16.3% better bump force management than traditional shocks.
  • 57% better traction than standard air-sprung shocks.
  • 39% fewer bottom-outs than a standard air spring.
  • Honed geometry for big bike capability and nimble feel.
  • SWAT downtube storage for carrying essentials.
  • Aftermarket shock links for wheel choice flexibility.
