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.
  • A 29" wheel version of our classic. The fully manipulated M5 alloy frame delivers superior ride quality, while the shared tube mono-stays increase lateral rigidity, and special forged dropouts let you switch to single speed.
  • The 29"-specific Fox F80RL is lightweight, torsionally rigid and provides plenty of adjustability.
  • Custom Avid Ultimate hydraulic disc brakes come with ultra-stiff caliper bodies, organic pads, carbon brake lever blades and single-speed hardware.
  • Our custom DT Swiss wheels don't cut corners when it comes to quality: 29" rims, sealed cartridge bearings, a DT Swiss rear hub with star ratchet and alloy freehub and DT Super Comp stainless spokes with alloy nipples. Exclusive to Specialized.
  • S-Works Fast Trak LK 2.0" tires roll insanely fast (just like XC champion Christoph Sauser), without sacrificing any traction.
