Overview

About this bike

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 650b wheels and wraps them in 650bx3.0" 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, Ohlins 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. - 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.
