It can be easy to say that a bike is revolutionary—that it features all of the latest and greatest technology. Rarely, however, is a trail bike so far ahead of the pack that it leaves you scratching your head wondering, "How'd they do that?" Well, the S-Works Stumpjumper FSR Carbon 6Fattie is that bike. It features our FACT 11m carbon fiber for the construction in order to provide an ultra-lightweight, strong, and stiff frame. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the 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. Then there's our 6Fattie Wheel System that takes 650b wheels and wraps them in 650bx3.0" tires to provide a drastic, life-changing level of traction, control, and floatation. Impressively, 6Fattie pulls this off without sacrificing anything to climbing prowess. 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 going to change the way that you ride 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 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. 
  • Roval Traverse SL 6Fattie carbon wheels work in tandem with the ultra-wide tires to give you loads of extra traction, floatation, and control.
