The Stumpjumper 15 Expert has arrived, ready to eliminate any compromises in trail riding. Does it handle rough patches on the trail like a big bike? Check. Does it have the control, playfulness, and efficiency of bikes with minimal suspension travel? Double check. What about various adjustable settings to perfectly customize your bike to your preferences and riding style? Check, check, check. EVEN MORE CAPABLE: Our new GENIE damper technology combines a playful and jump-friendly ride with the downhill capabilities of enduro bikes. EVEN MORE CONTROLLED: The Stumpjumper 15 offers better traction than our "Bike of the Year," the Stumpjumper EVO. ENDLESSLY CONFIGURABLE: With six different geometry settings, mullet or full 29er options, adjustable spring curves, and much more. GENIE LEAVES NO DESIRES UNFULFILLED: Our latest innovation is GENIE. The air damper technology meets the three greatest wishes of our riders: an almost "indestructible" air damper that provides 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 in the first 70% of the travel with the progressive spring rate of an air spring in the last 30%. This maximizes control and minimizes bottom-outs. GENIE offers the advantages of both steel and air springs while also allowing for tuning. Say goodbye to compromises. The future of trail riding starts now. BETTER IMPACT MANAGEMENT: With 16.3% improved impact management compared to conventional air-sprung dampers, GENIE in the Stumpjumper 15 makes it feel like the bike has significantly more suspension travel. For example, the Stumpjumper 15 with 145mm in the rear and our Enduro with 170mm both use 101mm of travel to absorb an impact force of 1080 N. MORE TRACTION: Extensive testing in the lab and on trails has shown that the Stumpjumper 15 with GENIE has 57% better traction than a conventional air-sprung damper. Our new GENIE technology delivers the smooth performance of a steel spring, resulting in better rear wheel contact with the ground than a standard air damper, enhancing power transfer and providing you with more control. LESS BOTTOMING OUT: The harder the hits, the more GENIE’s “silent reserve” fully expresses its potential: in the last 30% of travel, the damping resistance progressively increases, reducing potential bottom-out frequency and intensity. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, with a lightweight steering feel in tight sections and exceptional climbing efficiency. The spacious central cockpit centers riders for optimal traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset provide easy balance in challenging terrain due to enhanced stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike according to preferences and terrain. Head angle and bottom bracket height can be modified for optimal center of gravity or necessary ground clearance. MULLET OR FULL 29ER: Larger wheels offer better rollover and more momentum, or a smaller rear wheel for added playfulness? You have the choice. If you want to change the combination, we offer the appropriate linkage in our shop. No worries; geometry and suspension characteristics remain the same. SWAT BOX: The ingenious SWAT™ Box 4.0 in the downtube provides a weather- and crash-resistant storage compartment, now even more secure and better integrated in the Stumpjumper 15.
