We know full well that for many out there, the ultimate trail bike needs to possess the agility and responsiveness of a 650b trail bike. We tend to agree, which is why we're proud to introduce the S-Works Stumpjumper FSR 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 molding 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. And when you add-in an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, our proprietary Rx Trail Tune at the shock, and a build spec that spares no expense, you have a bike that, without a doubt, is ready for anything on the trail.
  • FACT 11m carbon fiber 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.
  • RockShox Pike RCT3 650b fork features a 15mm Maxle Stealth thru-axle and 150mm of plush travel.
  • Roval Traverse SL 650b carbon wheels work in tandem with the ultra-wide tires to give you loads of extra traction, floatation, and control.
