Overview

About this bike

After one ride on the Stumpjumper Expert 6Fattie, you'll never be merely "riding trail" again. It's a bold statement to make, but the increase in traction, control, and floatation that our 6Fattie Wheel/Tire System provides is nothing short of revolutionary. And then, of course, there's the rest of the bike. It features our FACT 9m carbon fiber for the bulk of 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 revolutionary 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. And when you factor in a build spec that has some of SRAM's best performing and durable components, you have a bike that will have you never looking back—unless it's to see your buddies eating your dust. - FACT 9m carbon fiber Trail Chassis with Stumpjumper FSR M5 alloy 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 FOX 34 Performance fork features 150mm of plush travel to take on big hits and bumpy terrain with supreme confidence and efficiency. - SRAM's 12-speed GX Eagle drivetrain, with a Truvativ Descendent crank, features an ultra-wide gear range that delivers climbing and descending efficiency in spades. On top of this, the one-by setup is notorious for being next to impossible to drop a chain with, plus it provides a significant weight savings in comparison to a standard two-by setup.
