The Stumpjumper 15 with GENIE gives me the advantages of a bike with generous travel, and also the advantages of a bike with reduced travel, all at once. - Allan Cooke. The Stumpjumper 15 erases any compromise in the trail world. Devour big obstacles like a bike with generous excursions? Check. Control, playfulness, and efficiency like an XC bike? Check. Wide customization options to make it perfect for the one biker who really matters: you? Check, check, check. REVOLUTIONARY CAPACITY: GENIE technology combines a snappy, playful ride with a DH-like hiking feel. SUPREME CONTROL: Tangibly better traction than the "Bike of the Year," the Stumpjumper EVO. GENIE-The Flying Carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology we invented fulfills every cyclist's three desires: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and an adjustable platform for a playful feel.THE 'GENIE': GENIE combines the linear stiffness of the coil spring that improves control through the "bump zone" with the progressive curve of the air spring at the end of the stroke to avoid bottom-outs. Truly, it is the best of both worlds-coil and air-with extra adjustability. Say goodbye to compromise and welcome the future of suspension. WHAT SHOCK?: With 16.3 percent better shock force management than a traditional air-spring shock, GENIE makes the Stumpy 15 perform like a bike with longer travel. For example, the Stumpjumper 15 (with 145mm rear wheel travel) and our Enduro (170mm travel) both use 101mm of travel to absorb a shock force of 1080N. GORGEOUS TRAction: Extensive field tests show that Stumpjumper 15 with GENIE provides 57% better traction than a standard air spring shock because GENIE technology offers flexible, coil spring-like performance that keeps the wheel in contact with the ground for a greater percentage of the time than a typical air spring. ADDIO BOTTOM OUT: 39% fewer bottom-out events than a standard air spring. In the case of large shocks, you will benefit from the progressive curve in the last 30% of the GENIE stroke. Thanks to two-stage behavior, GENIE reduces the frequency and severity of bottom-out events. PERFECT GEOMETRY: The geometry of this bike offers great capacity when you need it, agility in tight sections, and efficiency when climbing. The wide cockpit centers you on the bike, optimizing traction and control in corners. The low bottom bracket, relaxed head angle, and optimized fork offset promote stability even in technical terrain. YOUR WAY: The Stumpjumper 15 seamlessly integrates geometry adjustment, making it the most customizable trail bike ever. Six distinct geometry settings let you fine-tune performance for any style and terrain. Steering angle and bottom bracket height can be precisely adjusted for stability or light. WHEEL CHOICE: With our aftermarket links you can choose from large wheels on both the front and rear, or you can use a 27.5" rear wheel for a more responsive and playful ride. Whichever you choose, the geometry is not affected. CARRY ALL YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 increases space in the down tube, an innovation we pioneered.
