The Stumpjumper 15 Alloy Comp is designed to tackle any trail challenge with ease. Can it handle big obstacles like a larger bike? Absolutely. Does it possess the control, playfulness, and efficiency of bikes with shorter travel? Definitely. Is it customizable to perfectly match the rider and their style? Without a doubt. EVEN MORE POWERFUL: The new GENIE damping technology combines a playful ride with the downhill capabilities of enduro bikes. EVEN MORE CONTROL: The Stumpjumper 15 Alloy offers superior traction compared to the award-winning Stumpjumper EVO. ENDLESSLY CUSTOMIZABLE: Six distinct geometry settings, mullet or full 29er options, adjustable spring curves, and much more. GENIE LEAVES NO WISH UNFULFILLED: Our latest innovation, GENIE, meets the top three desires of riders: an almost insurmountable air damper with the smooth feel of a steel spring—plus ultra-fine adjustability. THE BEST OF BOTH WORLDS: GENIE combines the linear spring rate of a steel spring for the first 70% of travel with the progressive spring rate of an air spring for the last 30%. This maximizes control and prevents bottom-outs. GENIE offers the best of both worlds—steel and air spring—along with tuning capabilities. Say goodbye to compromises. The future of trail riding is here. IMPROVED IMPACT FORCE MANAGEMENT: With a 16.3% enhanced impact force management, GENIE in the Stumpjumper 15 makes the bike feel like it has much more travel. For example, both the Stumpjumper 15 Alloy and our enduro bike use 101 mm of travel to absorb an impact force of 1080 N. MORE TRACTION: Extensive testing shows that the Stumpjumper 15 Alloy with GENIE delivers 57% better traction than conventional air-sprung dampers. The new GENIE technology provides the smooth performance of a steel spring, improving ground contact and enhancing control. LESS BOTTOM-OUTS: The harder the hits, the more GENIE reveals its potential: In the last 30% of travel, the damping resistance increases progressively, reducing the frequency and intensity of bottom-outs. PROGRESSIVE TRAIL GEOMETRY: The bike's geometry offers great capabilities, a light steering feel in tight sections, and extremely efficient climbing. The spacious cockpit provides excellent traction and cornering control, while the low bottom bracket, slack head angle, and optimized fork offset contribute to stable balance. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust ergonomics and efficiency. The steering angle and bottom bracket height can be modified for optimal center of gravity or necessary ground clearance. MULLET OR FULL 29ER: Choose larger wheels for better rollover or a smaller rear wheel for more playfulness—it's up to you. If you want to change the combination, we offer the appropriate linkage. Geometry and suspension remain consistent. SWAT BOX: The reliable SWAT™ Box 4.0 in the down tube features a weatherproof and crash-proof storage compartment, now even better integrated.
