At a glance

The 2018 Specialized S-Works Stumpjumper 29/6Fattie is an All Mountain Carbon mountain bike. It sports 29" wheels and a SRAM drivetrain. The bike is part of Specialized's S-Works Bikes range of mountain bikes.

- When only the best will do, you need the ultimate trail bike. In other words, you need the S-Works Stumpjumper 29/6Fattie. 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 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 to make things even better, the Stumpy’s design also allows you the opportunity to toggle between 29-inch wheels and 6Fattie wheels (not included), allowing the ultimate in configuration options for the trail at hand. For the spec, we included a build that spares no expense and features a full SRAM XX1 Eagle groupset, SRAM Guide RS brakes, Öhlins front and rear suspension, and hand-built Roval Carbon wheels, so you get a bike that’s ready for anything on the trail.
