S-Works Carbon HT Disc
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 S-Works FACT 10m carbon frame is as fast as it is beautiful - a carbon drive-side with forged disc, non-drive dropouts and tapered head tube for increased rigidity.
  • The smartest fork on the trail. Our Specialized Future Shock S90 with Brain Fade technology (borrowed from our Epic shock) allows you to fine tune your ride, while a tapered carbon steerer increases front end stiffness.
  • Custom Avid Ultimate hydraulic disc brakes with lightweight magnesium lever body and carbon blade, titanium hardware and alloy-backed organic pads provide modulation and control at every speed.
  • The S-Works oversized carbon crankset is feathery light and incredibly stiff, spinning smoothly on an integrated oversize BB - it's the heart of a great drivetrain.
  • Roval Controle SL wheels are lightweight and XC race-ready, with high quality Swiss-made internals and DT Aerolite butted spokes.
