Stumpjumper 15 EVO Expert 2026

Description

Stumpjumper 15 with GENIE gives you the advantages of a bike with generous travel and those of a bike with shorter travel, all together. – Allan Cooke. The Stumpjumper 15 eliminates every compromise in the world of trail riding. Devour big obstacles like a long-travel bike? Done. Control, playfulness and efficiency like an XC bike? Done. Wide customization options to make it perfect for the only rider who really matters: you? Done, done, done. REVOLUTIONARY CAPABILITY: GENIE technology combines a snappy, playful ride with the feel of DH-level travel. SUPREME CONTROL: Noticeably better traction than the "Bike of the Year," the Stumpjumper EVO. CUSTOMIZATION: Six geometry settings, mullet or 29er wheel configurations, adjustable compression curve, and much more. GENIE—The magic carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology, invented by us, grants every rider's three wishes: 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 "GENIUS": GENIE combines the linear stiffness of a coil spring, which improves control through the "mid-stroke," with the progressive curve of an air spring at the end of the stroke to prevent bottom-outs. Really, it's the best of both worlds, coil and air, with extra adjustability. Say goodbye to compromises and welcome the future of suspension. WHICH IMPACT?: With impact management 16.3% better than a traditional air shock, GENIE makes the Stumpy 15 perform like a bike with greater travel. For example, the Stumpjumper 15 (with 145 mm rear wheel travel) and our Enduro (170 mm travel) both use 101 mm of stroke to absorb an impact force of 1080 N. TRACTION GALORE: Extensive field testing shows that the Stumpjumper 15 with GENIE delivers 57% better traction than a standard air spring shock, because GENIE technology offers flexible, coil-like performance that keeps the wheel in contact with the ground for a greater percentage of the time than a typical air spring. BYE-BYE BOTTOM OUT: 39% fewer bottom-out events than a standard air spring. On big hits, you'll benefit from the progressive curve in the final 30% of GENIE's stroke. Thanks to its two-stage behavior, GENIE reduces the frequency and severity of bottom-out events. REFINED GEOMETRY: This bike's geometry offers great capacity when it matters, agility in tight sections, and efficiency on climbs. 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 on 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. The head angle and bottom bracket height can be precisely adjusted to ensure stability or agility. WHEEL CHOICE: With our aftermarket links you can choose large wheels front and rear, or run a 27.5" rear wheel for a more responsive, playful ride. Whatever you choose, the geometry remains unaffected. CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 increases space in the down tube.
