Specialized Stumpjumper 15 Comp Bike (2025)

Specialized Stumpjumper 15 Comp Mountain Bike for Enduro, 2025 model in brown color. Specialized Reference: 93325-5104

The Stumpjumper 15 is here to overcome all the pros and cons of trail riding. Does it handle bumps like a big bike? Check. Short-travel control, fun, and efficiency? Double check. How about a good dose of customization to make it perfect for the one rider who truly matters: you? Check, check, check...

• INCREDIBLE CAPABILITY: The GENIE shock technology combines a lively, playful ride with a bottomless DH feel.
• MAXIMUM CONTROL: Better traction than the "Bike of the Year" Stumpjumper EVO.
• GENIE - The Magic Carpet Ride: The biggest innovation of the Stumpjumper 15 is GENIE. This pending-patent air shock technology delivers the three wishes of every rider: the feel and control of a coil, better bottom-out prevention than a standard air shock, and an adjustable "platform" for a playful feel.
• ILLUMINATE GENIE: GENIE combines the linear elasticity of a coil for improved control in the "bump zone" with the progressive elasticity of an air spring at the end of the travel to avoid bottoming out. Truly, it's the best of both worlds, coil, and air, with more adjustability. Say goodbye to compromises and hello to the future of riding: With 16.3% better bump force management than a traditional air shock, GENIE makes the Stumpy 15 ride like a bike with more travel. For example, the Stumpjumper 15 (with 145 mm of rear wheel travel) and our Enduro (170 mm of travel) use 101 mm of travel to absorb a bump force of 1080 N.
• WIDE TRACTION: Extensive field testing shows that the Stumpjumper 15 with GENIE offers 57% more traction than a standard air shock, as the GENIE technology provides flexible, coil-like performance, keeping the wheel in contact with the ground a higher percentage of the time than a typical air shock.
• GOODBYE BOTTOM OUTS: 39% fewer bottom-outs than a standard shock. During large impacts, it benefits from the rate increase in the last 30% of the GENIE's travel. Due to this steep, two-stage rate increase, GENIE reduces the frequency and severity of bottom-outs. OPTIMIZED GEOMETRY: The geometry of this bike offers the capability of a large bike when you need it, an agile feel in playful sections, and nimble, efficient behavior on climbs. The generous cockpit centers you on the bike, optimizing traction and control in corners. The low bottom bracket, slack head angle, and optimized fork offset maintain stability on rough terrain.
• RIDE YOUR WAY: The Stumpjumper 15 seamlessly integrates benchmark geometry adjustment, making it the most customizable trail bike in history. Six different geometry adjustments allow you to tailor the performance for any style on any terrain. The head angle and bottom bracket height can be finely tuned for stability or clearance.
• WHEELS FOR ALL: With our aftermarket shocks, you can choose between large wheels front and rear or mix things up with a 27.5" rear for a more responsive and playful ride. Whatever you choose, the geometry remains unaffected.
• CARRY IT ALL: The SWAT 4.0 on the Stumpjumper 15 increases storage in the downtube, an innovation we pioneered. It's the most weather-resistant storage system.
• MORE RELIABLE THAN YOU: Our full-suspension bikes are built to be relentless, designed to withstand years of hard riding, and backed by the best support and policies to keep you on the trail. Our unbeatable lifetime guarantee on suspension pivot bearings to the original owner is just one way we've got you covered.
