Stumpjumper Pro 27.5
2018 Stumpjumper Pro 27.5
Why should S-Works have all the fun? With our Stumpjumper Pro 27.5, you get most of the same performance features, like custom Öhlins suspension, plus the flick-able, quick-handling ride you'd expect out of a 27.5 wheel size.
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. 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.
And for this model, we outfitted the Pro with a high-performing build spec that features a SRAM X01 Eagle drivetrain, SRAM Guide RS brakes, Öhlins front and rear suspension, and hand-built Roval Traverse carbon wheels, so you get a bike that, without a doubt, is ready for anything on the trail.
