Frame S-Works Stumpjumper 15 EVO 2026

Description

The Stumpjumper 15 with GENIE gives you the advantages of a bike with generous travel, and also those of a bike with short travel, all together. – Allan Cooke. The Stumpjumper 15 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. Plenty of customization options to make it perfect for the one rider that really matters: you? Done, done, done. REVOLUTIONARY CAPABILITY: GENIE technology pairs snappy, playful handling with DH-level suspension feel. SUPREME CONTROL: Tangibly better traction compared to "Bike of the Year," the Stumpjumper EVO. PERSONALIZATION: Six geometry settings, mullet or 29er wheel builds, adjustable compression curve, and more. GENIE—The magic carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology we invented fulfills every cyclist's three wishes: the feel and control of a coil spring, better bottom-out resistance than a standard air spring and an adjustable platform for playful feel. THE 'GENIUS': GENIE combines the linear stiffness of coil spring that boosts control through the "impact zone" with the progressive curve of the air spring at the end of travel to prevent bottom-outs. Truly, it's the best of both worlds – coil and air – with extra adjustability. Say goodbye to compromises and welcome the future of suspension. WHAT IMPACT?: With impact force management 16.3% better than a traditional air spring shock, GENIE makes the Stumpy 15 perform like a bike with more 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 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. GOODBYE BOTTOM OUT: 39% fewer bottom-out events compared to a standard air spring. In the case of big hits, you'll benefit from the progressive curve in the final 30% of GENIE travel. Thanks to its two-stage behavior, GENIE reduces the frequency and severity of bottom-out events. REFINED GEOMETRY: this bike's geometry delivers serious 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 tube 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 trailbike 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 dial in stability or quickness. WHEEL CHOICE: With our aftermarket links you can choose 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 increases space in the down tube, an innovation we pioneered.
