It's 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 6Fattie/29 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/Tire System that takes 27.5 wheels and wraps them in 27.5x3.0" tires to provide a drastic, life-changing level of traction, control, and floatation. Impressively, 6Fattie pulls this off without sacrificing anything to climbing prowess. This system also allows you the opportunity to toggle between 29-inch wheels (not included) and 6Fattie wheels, allowing the ultimate in configuration options for the trail at hand. Further improving the ride, you'll also find an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, a slacked out front end, and our proprietary Rx Trail Tune at the shock.
For this S-Works model, we outfitted it with a build spec that spares no expense—featuring a full SRAM XX1 Eagle 12-speed groupset, SRAM Guide RS brakes, Öhlins front and rear suspension, and hand-built Roval Traverse SL carbon wheels. With the Stumpjumper, you have a bike that, without a doubt, is ready for anything on the trail.
