Stumpjumper 15 EVO Comp Alloy 2026

Description

Stumpjumper 15 Alloy with GENIE gives you the advantages of a bike with generous travel and those of one with reduced travel, all at once. – Allan Cooke. The Stumpjumper 15 Alloy eliminates every compromise in the trail world. Devour big obstacles like a long-travel bike? Done. Control, playfulness and efficiency like an XC bike? Done. Extensive 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. GENIE—The magic carpet: The biggest innovation on the Stumpjumper 15 Alloy is GENIE. This patent-pending air spring technology, invented by us, grants the three wishes of every rider: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and an adjustable platform for a playful ride. THE 'GENIUS': GENIE combines the linear stiffness of a coil spring, which improves control through the "mid-stroke zone," with the progressive curve of an air spring at the end of the stroke to prevent bottoming out. Really, it's the best of both worlds – coil and air – with extra tuning options. Say goodbye to compromises and welcome the future of suspension. WHICH IMPACT?: With impact management 16.3% better than a traditional air-sprung shock, GENIE makes the Stumpy 15 perform like a bike with more travel. For example, the Stumpjumper 15 Alloy (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 Alloy with GENIE delivers 57% better traction than a standard air-sprung shock, because GENIE's flexible, coil-like performance keeps the wheel in contact with the ground for a greater percentage of the time than a typical air spring. GOODBYE 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 you need it, agility in tight sections, and efficiency on climbs. The wide cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, relaxed head angle and optimized fork offset promote stability even on technical terrain. YOUR WAY: The Stumpjumper 15 Alloy seamlessly integrates geometry adjustment, making it the most customizable trail bike ever. Six geometry settings let you fine-tune performance for any riding style and terrain. The head angle and bottom bracket height can be precisely adjusted to deliver stability or agility. WHEEL CHOICE: With our aftermarket links, you can choose big wheels front and rear, or run a 27.5" rear wheel for a more responsive and playful ride. Whichever you choose, the geometry is unaffected. CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 Alloy increases space in the down tube, an innovation we pioneered.
