S-Works Stumpjumper FSR 650b Frame

2017 S-Works Stumpjumper FSR 650b Frame

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.
