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. Huge customization possibilities to make it perfect for the only biker who really counts: you? Done, done, done. REVOLUTIONARY CAPABILITY: GENIE technology pairs snappy, playful handling with a DH suspension feel. SUPREME CONTROL: Tangibly better traction compared to "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 we invented fulfills the three wishes of every cyclist: the feel and control of a coil spring, better bottom-out prevention compared to a standard air spring and an adjustable platform for a playful feel. THE 'GENIUS': GENIE combines the linear stiffness of the coil spring that enhances control through the "impact zone" with the progressive curve of the air spring at the end of the stroke to prevent bottoming out. Truly, it's the best of both worlds – coil and air – with extra adjustment possibilities. Say goodbye to compromises and welcome the future of suspension. WHICH IMPACT?: With impact force management 16.3% better than a traditional air spring shock, GENIE makes the Stumpy 15 perform like a bike with greater 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: In-depth field testing shows that Stumpjumper 15 Alloy with GENIE delivers 57% better traction than a standard air spring shock because GENIE technology offers flexible performance, similar to a coil spring, which keeps the wheel in contact with the ground for a greater percentage of the time compared to 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 travel. Thanks to two-stage behavior, GENIE reduces the frequency and severity of bottom-out events. REFINED GEOMETRY: this bike's geometry offers huge capability 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 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 trailbike ever. Six distinct geometry settings let you fine-tune performance for any style and terrain. Head angle and bottom bracket height can be precisely adjusted to guarantee stability or playfulness. 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 snappier, more playful handling. Whatever you choose, geometry isn't affected. CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 Alloy increases space in the down tube, an innovation we pioneered.
