Specialized Stumpjumper 15 EVO Alloy Comp - S3, Gloss Grey Blue / Cast Blue Metallic, 2026

The Stumpjumper 15 Alloy is here to erase all the compromises made in the trail world on bikes. Soak up bumps like a bike with big travel? We've got. Handling, playfulness, and short-stroke efficiency? Double-checked. How about a hefty helping of personalization to make it perfect for the only rider that really matters - you? We've got it, we've got it and we've got it. BREAKTHROUGH CAPABILITY: GENIE shock technology combines a nimble, playful ride with bottomless DH feel. UNIQUE CONTROL: Measurably better traction than the "bike of the year" Stumpjumper EVO. UNSURPASSABLE PERSONALIZATION: Six geometry settings, mixed wheels or 29", tunable suspension curve and more. GENIE-Riding on a flying carpet: the biggest innovation on the Stumpjumper 15 Alloy is GENIE. This patent-pending air spring technology we invented fulfills three desires of every trail rider: coil spring-like feel and control, better bump prevention than a standard air spring, and a tunable "platform" for a playful feel. The GENIE combines the linear suspension of a coil spring, which improves ride control in the "impact zone", with the progressive springing of an air spring at the end of the stroke to prevent bump stops. It really is the best of both worlds - coil and air - with the option of additional tuning. Say goodbye to compromise and hello to the future of riding. WHAT A BUMPY RIDE: With 16.3% better shock absorption than traditional GENIE air shocks, the Stumpjumper 15 Alloy rides like a bike with more travel. For example, the Stumpjumper 15 Alloy (with 145 mm of rear wheel travel) and our Enduro model (with 170 mm of rear wheel travel) both use 101 mm of travel to absorb 1080 N of impact force. TRAction: Extensive field testing has shown that the Stumpjumper 15 Alloy with GENIE technology provides 57% better traction than standard air-suspension shock absorbers because GENIE technology provides coil spring-like performance that keeps the wheel in contact with the ground a greater percentage of the time than a typical air spring. SBOHEM STOPS: 39% less stops than a standard air spring. In big bumps, you benefit from a rising spring curve in the last 30% of the GENIE's travel. With this two-stage, dramatically rising curve, GENIE reduces the frequency and severity of stops. PERFECT GEOMETRY: This bike's geometry provides big-wheel capability when you need it, agility in tight sections, and lively and efficient climbing. The generous cockpit seats you perfectly on the bike and optimizes traction and cornering control. The low centre, laid-back head tube angle and optimised fork offset ensure stability on off-road terrain. RIDE YOUR WAY: The Stumpjumper 15 Alloy seamlessly integrates a reference geo setup, making it the most adaptable trail bike ever. Six different geometry settings let you fine-tune the performance for any style and terrain. Head angle and center height can be fine-tuned for stability or trailability. CHOICE OF WHEELS: With our aftermarket swaybars, you can choose between big wheels front and rear, or mix it up with a 27.5" rear wheel for a more responsive and playful ride. No matter what you choose, the geometry will remain the same. TAKE IT ALL: The SWAT on the Stumpjumper 15 Alloy increases storage space on the downtube, an innovation we were the first to introduce. It's the smoothest-functioning, most weather-resistant flush-mount system ever. MORE WEIGHT THAN YOU CAN STAND: Our full-suspension bikes are built to be tireless, designed to withstand years of hard riding, and backed by the best support and lockouts to keep you on the trail. Our unbeatable first-owner, no-questions-asked lifetime suspension pivot bearing replacement is just one of the ways we take care of you.
