The Stumpjumper 15 Alloy Comp is here and ready to eliminate any compromises in trail performance. Does it handle rough terrain like a big bike? Yes. Does it provide the control, playfulness, and efficiency of bikes with less suspension travel? Absolutely. And what about various adjustment options to tailor the bike perfectly to you and your riding style? Yes, yes, yes. EVEN MORE COMPETITIVE: Our new GENIE shock technology merges a playful and springy ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROL: The Stumpjumper 15 Alloy Comp offers better traction characteristics than our "Bike of the Year," the Stumpjumper EVO. ENDLESSLY CUSTOMIZABLE: Six different geometry settings, Mullet or Full 29er, adjustable spring curve, and much more. GENIE MEETS ALL DEMANDS: Our latest innovation is GENIE. This air shock technology fulfills the three biggest wishes of our riders: an almost “unbreakable” air shock with the smooth riding 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 delivers the best of both worlds – steel and air springs – along with tuning options. Say goodbye to compromises. The future of trail riding begins now. BETTER IMPACT MANAGEMENT: With 16.3% better impact management than conventional air-sprung shocks, GENIE ensures that the Stumpjumper 15 feels like it has much more travel. For instance, the Stumpjumper 15 Alloy with 145 mm rear travel and our Enduro with 170 mm both utilize 101 mm travel to absorb an impact force of 1080 N. MORE TRACTION: Extensive testing in the lab and on the trails has shown that the Stumpjumper 15 Alloy with GENIE has 57% better traction characteristics compared to a conventional air-sprung shock. Our new GENIE technology offers the smooth performance of a steel spring, ensuring more rear wheel contact than a standard air-sprung shock. Your power transfer is improved, providing you with better control. LESS BOTTOM-OUTS: The harder the hits, the more the “silent reserve” of GENIE shows its full potential: In the last 30% of travel, the damping resistance progressively increases, reducing the potential frequency and intensity of bottom-outs. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, a light, agile steering feel in tight sections, and tremendously efficient climbing behavior. The central, spacious cockpit centers riders for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset offer effortless balance in challenging terrain thanks to great stability. A FRAME FULL OF OPTIONS: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike according to preferences and terrain. The head angle and bottom bracket height can be modified for the optimal center of gravity or necessary ground clearance. MULLET OR FULL 29ER: Large wheels for better rollover behavior 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 suitable link in our shop. And don’t worry, geometry and handling characteristics remain the same. SWAT BOX: The ingenious SWAT™ Box 4.0 in the down tube provides a wind-, weather-, and crash-proof storage compartment, even more secure and better integrated in the Stumpjumper 15 Alloy Comp.
