2018 Specialized S-Works SJ FSR Carbon Frame 29/6Fattie

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 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.

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 rear shock. This frame also includes a custom Öhlins STX rear shock with our venerable, easy-to-set-up AUTOSAG system. This Stumpy's design also allows you the opportunity to toggle between 29-inch wheels and 6Fattie wheels (not included), allowing for the ultimate in configuration options for the trail at hand.
