At a glance

The 2017 Specialized S-Works Stumpjumper FSR 650b is an All Mountain Carbon mountain bike. It has RockShox suspension and a SRAM drivetrain. The bike is part of Specialized's Stumpjumper range of mountain bikes.

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 moulding process also allowed us to revolutionise 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.
