The days of coil suspension only appearing on the bikes of Enduro World Series pros, like Curtis Keene and Jared Graves, are over. Now, with the Specialized Stumpjumper Coil Carbon 29er Mountain Bike 2018 you too can experience the exceptional pedalling efficiency and downhill-crushing damping that comes with a coil shock. 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 all-new 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 to complement the 29-inch wheels that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end. Handling suspension duties out back is the revolutionary Öhlins twin tube coil shock, making for the perfect combination of pedaling efficiency and downhill-smashing damping that will have you going faster both up and down the trail. And to make things even better, the 2018 Stumpjumper 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 2018 Stumpjumper Coil Carbon, Specialized outfitted it with SRAM's simple GX one-by shifting, SRAM Guide R brakes, Öhlins front and rear suspension, and hand-built Roval Traverse carbon wheels. Specialized Stumpjumper Coil Carbon 29er 2018 Features FACT 11m carbon fibre Trail Chassis with Stumpjumper FSR full carbon rear end blends stiffness with light-weight to form the pinnacle of efficiency, complete with fully enclosed cable routing. Integrated SWAT Door & Stem Top Cap create zero-hassle storage. The Öhlins TTX 22 M twin tube coil shock delivers the ultimate combination of efficiency & damping abilities. Complete with multiple high-speed & low-speed compression + rebound adjustment options. Featuring a three-chamber air spring, the Öhlins RXT 36 fork stays smooth and high in the travel without compromising bump absorption, traction, or stability. it also features low-speed and rebound adjustments, and sports 150mm of plush travel. SRAM's 11-speed GX groupset features a 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.
