We know full well that for many out there, the ultimate trail bike needs to possess the agility and responsiveness that comes with 650b wheels. We tend to agree, which is why we developed the S-Works Stumpjumper 650b. It reflects everything that we've learned over the years, and in our eyes, represents the pinnacle of trail performance.

Starting at the carbon layup, it features our highest-end FACT 11m for an ultra-lightweight, strong, and stiff construction. The carbon moulding process also allowed us to revolutionize how you carry your trail essentials with the all-new SWAT™ Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame. Further improving the ride, you'll also find an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, a slacked out front end, and our proprietary Rx Trail Tune at the shock.

For this S-Works model, we outfitted it with a build spec that spares no expense. This means that it's loaded with a full SRAM XX1 Eagle groupset, SRAM Guide RS brakes, Öhlins front and rear suspension, and hand-built Roval Carbon wheels. So with this Stumpjumper, you have a bike that, without a doubt, is ready for anything on the trail.

  • FACT 11m carbon fibre Trail Chassis with Stumpjumper FSR full carbon rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT™ Door create exceptional handling and zero-hassle storage.
  • The Öhlins RXF 36 fork was designed to be the gold standard in frontend suspension. It operates off of a three-chamber air spring design (two positive and one negative), and it utilizes proprietary TTX damping technology. Combined, this allows both parallel and separated oil flow that controls the overall pressure levels.
  • The XX1 Eagle drivetrain is the pinnacle of shifting performance, floating through the 12-speed cassette with crisp, precise shifts.

Occasionally, without notice, manufacturers change product design and/or specifications.
