Stumpjumper 15 EVO Comp Alloy 2026

Description

The Stumpjumper 15 Alloy with GENIE gives you the advantages of a bike with generous travel, and also those of a bike with reduced travel, all together. – Allan Cooke. The Stumpjumper 15 Alloy erases every compromise in the trail world. Devour big obstacles like a bike with generous travel? Done. Control, playfulness and efficiency like an XC bike? Done. Wide customization options to make it perfect for the only biker that really counts: you? Done, done, done. REVOLUTIONARY CAPABILITY: GENIE technology pairs snappy, playful handling with a DH-level suspension feel. SUPREME CONTROL: Tangibly better traction compared to 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 cyclist: 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 the coil spring that improves control through the "impact zone" with the progressive curve of the air spring at the end of the stroke to prevent bottom-outs. Truly, it's the best of both worlds – coil and air – with extra tunability. Say goodbye to compromises and welcome the future of suspension. WHICH IMPACT?: With impact force management 16.3% better than a traditional air spring damper, GENIE makes the Stumpy 15 perform like a bike with greater travel. For example, the Stumpjumper 15 Alloy (with rear wheel travel of 145 mm) and our Enduro (travel of 170 mm) both use 101 mm of stroke to absorb an impact force of 1080 N. TRACTION GALORE: Extensive field testing shows that Stumpjumper 15 Alloy with GENIE delivers 57% better traction than a standard air spring damper 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. GOODBYE BOTTOM OUT: 39% fewer bottom-out events compared to a standard air spring. In case of big hits, you'll benefit from the progressive curve in the final 30% of GENIE stroke. Thanks to its two-stage behavior, GENIE reduces the frequency and severity of bottom-out events. REFINED GEOMETRY: This bike's geometry offers big capacity when you need it, agility in tight sections, and climbing efficiency. The wide cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, relaxed head tube angle and optimized fork offset promote stability even on technical terrain. YOUR WAY: The Stumpjumper 15 Alloy perfectly 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. Head tube angle and bottom bracket height can be precisely adjusted to give you stability or clearance. WHEEL CHOICE: With our aftermarket links you can choose between large wheels on both front and rear, or you can run a 27.5″ rear wheel for more responsive, playful handling. Whatever you choose, geometry isn't compromised. CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 Alloy increases space in the down tube, an innovation we pioneered.
