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.
  • M5 fully manipulated alloy frame, with new larger-diameter ORE top/down tube for superior ride quality and shared tube mono-stays for lateral rigidity.
  • The Fox F90 suspension fork is built light and stiff for XC racing with 90mm travel, compression/rebound adjust and lockout.
  • The custom Shimano crankset is light, stiff and shifts smooth in every condition.
  • S-Works Fast Trak LK tires roll fast and grip tight in race conditions thanks to dual compound treads.
