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.
  • Custom DT Swiss wheels are superior in weight and class: 24mm wide, 28h front, 32h rear with eyelets laced to a precision DT Swiss rear hub by DT Swiss stainless spokes.
  • FACT 9m carbon frame with an oversize 1.5" lower bearing accelerates like a rocket, climbs like a champ and flicks through switchbacks.
  • You want a Stumpy hardtail for all out speed, and that’s why we spec'd the lightweight RockShox SID Race - 90mm travel for the rough stuff, a lockout for efficient climbing and excellent adjustability for everything in between.
