Stumpjumper 15 Comp Alloy - Shimano SLX, FOX Rhythm - Gloss Smoke / Cool Grey / S2

The Stumpjumper 15 Alloy is designed to eliminate trade-offs in trail riding. It delivers the bump-absorbing capability of a larger bike while maintaining short-travel control, playfulness, and climbing efficiency. The bike features extensive personalization options to suit individual rider preferences and styles.The breakthrough innovation on this bike is GENIE Shock Technology, a patent-pending air spring system that combines the best characteristics of both coil and air springs. GENIE provides the maximum grip and traction of a coil spring feel, better bottom-out prevention than a standard air spring, and the ability to tune mid-stroke and end-stroke support independently. This technology delivers 16.3% better bump force management than traditional air springs, allowing the 145mm rear travel bike to absorb impacts like a 170mm travel enduro bike.Traction performance is exceptional, with GENIE delivering 57% better traction than standard air-sprung shocks by maintaining supple, coil-like performance that keeps the wheel in contact with the ground more consistently. The technology also reduces bottom-outs by 39% compared to standard air springs through its two-stage rising rate in the final 30% of the stroke.Geometry is honed for versatility, delivering big bike capability when needed, nimble handling in tight sections, and efficient climbing characteristics. The generous cockpit centers the rider for optimized traction and corner control, while the low bottom bracket, slack head tube angle, and optimized fork offset provide stability in rough terrain. Six distinct geometry settings allow fine-tuning of head angle and bottom bracket height for stability or clearance preferences.Wheel configuration is customizable through aftermarket shock links, allowing riders to choose between 29-inch wheels front and rear or mix a 27.5-inch rear for a more responsive and playful ride without affecting geometry. The bike features SWAT downtube storage integration for carrying essentials on the trail.The frame is constructed from M5 alloy with SWAT door integration, sealed cartridge bearing pivots, and internal cable routing. The FOX FLOAT 36 Rhythm fork with GRIP damper provides responsive front suspension, while TRP Trail EVO 4-piston hydraulic disc brakes deliver powerful stopping performance. The Shimano SLX drivetrain offers performance-focused, durable shifting, and the X-Fusion Manic dropper post provides infinite adjustability. Specialized backs the bike with a lifetime, no-questions-asked replacement warranty for suspension pivot bearings to the original owner.GENIE Grants Every Trail Rider's WishesThis game-changing, patent-pending air spring technology that we invented grants every trail rider three wishes: feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable "platform" for a playful feel.What's Inside GENIE?Check out how GENIE combines the control-enhancing linear spring rate of a coil spring through the "bump zone" with the progressive spring rate of an air spring at the end of the stroke to reduce bottom-outs. It's the best of both worlds - coil and air - with extra tuneability.

It literally uses more travel for the same size bump, thanks to its flatter spring curve in the first 70% of travel.57% Better TractionGENIE delivers 57% less traction loss time than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground a greater percent of the time than a typical air spring would.Bye, Bye, Bottom OutsSend it with confidence knowing that in field testing GENIE eliminated 39% of severe bottom out events compared to a standard FOX Float air spring.Meet the CreatorsMany (dirty) hands, one (awesome) bike.
