When only the best, most agile trail bike will do, you're looking at the world with a different pair of eyes. To fulfill your needs, you need the S-Works Stumpjumper FSR 650b. It reflects everything that we've learned over the years, and in our eyes, represents the pinnacle of perfection. 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, plus our proprietary Rx Trail Tune at the shock, 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.
  • The custom Öhlins STX single tube air shock at the rear features high- and low-speed compression, as well as low-speed rebound. You'll also find an extra-volume reservoir that allows for more oil, which results in more control and an ultra-plush ride quality.
