Overview
About this bike
When only the best will do, you need the ultimate trail bike. In other words, you need the Specialized S-Works Stumpjumper 29/6Fattie. It reflects everything that Specialized has learned over the years and represents the pinnacle of trail performance. Starting at the carbon layup, it features their highest-end FACT 11m for an ultra-lightweight, strong, and stiff construction. The carbon molding process also allowed them to add 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 a 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, allowing the ultimate in configuration options for the trail at hand. For the spec, they included a build that spares no expense and features a full SRAM XX1 Eagle groupset, SRAM Guide RS brakes, Ohlins front and rear suspension, and hand-built Roval Carbon wheels, so you get a bike that's ready for anything on the 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 Ohlins 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. - The XX1 Eagle drivetrain is the pinnacle of shifting performance, floating through the 12-speed cassette with crisp, precise shifts.
