Technical Specifications
STILL LEAVING ITS COMPETITION IN THE DUST after decades in production, the Stumpjumper® Hardtail makes no apologies for being the leanest, lightest (some models are under 20 lbs.) and most precision hardtail on the market. Tradition works.
  • The bike that started it all, in a updated 29" package - the M5 alloy frame with oversized ORE top/down tube and perfect geometry makes you forget you're riding big hoops. Forged dropouts let you switch between geared or single speed.
  • Custom Avid Elixir hydraulic disc brakes offer excellent modulation thanks to organic pads, adjustable levers and size-specific rotors in a lightweight set up.
  • S-Works Fast Trak LK 2.0" tires roll insanely fast (just like XC champion Christoph Sauser), without sacrificing any traction.
