The Stumpjumper 15 Alloy Comp is here and ready to eliminate any compromises in the trail game. Does it absorb bumps on the trail like a big bike? Check. Does it possess the control, playfulness, and efficiency of bikes with less travel? Double check. And how about various adjustment options to perfectly tailor your bike to your preferences and riding style? Check, check, check. EVEN MORE CAPABLE: Our new GENIE shock technology combines a playful and agile ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROLABLE: The Stumpjumper 15 Alloy offers better traction characteristics than our "Bike of the Year," the Stumpjumper EVO. ENDLESSLY CONFIGURABLE: Six different geometry settings, mullet or full 29er, adjustable spring curve, and much more. GENIE LEAVES NO WISH UNFULFILLED: Our latest innovation is GENIE. This air shock technology fulfills the three biggest desires of our riders: an almost "uncrushable" air shock with the smooth ride 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 stroke with the progressive spring rate of an air spring in the last 30%. This maximizes control and avoids bottom-outs. GENIE offers the best of both worlds – steel and air springs – along with tuning options. Say goodbye to compromises. The future of trail riding starts now. BETTER IMPACT MANAGEMENT: With 16.3% better impact management than conventional air shocks, GENIE in the Stumpjumper 15 ensures that the bike feels like it has much more travel. For example, both the Stumpjumper 15 Alloy with 145 mm of rear travel and our Enduro with 170 mm utilize 101 mm of travel to absorb an impact force of 1080 N. MORE TRACTION: Extensive lab and trail testing have shown that the Stumpjumper 15 Alloy with GENIE has 57% better traction characteristics compared to a standard air shock. Our new GENIE technology delivers the smooth performance of a steel spring, providing better rear wheel contact than a regular air shock. Your power is transferred more effectively, giving you more control. LESS BOTTOM-OUTS: The harder the hits, the more GENIE's "silent reserve" unleashes its full potential: in the last 30% of the travel, 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, with a light and agile steering feel in tight sections and incredibly efficient climbing behavior. The central, spacious cockpit centers the rider for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset provide easy balance even in challenging terrain, thanks to plenty of stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bikes according to preferences and terrain. Head angle and bottom bracket height can be modified for the optimal center of gravity or required ground clearance. MULLET OR FULL 29ER: Large wheels for better rollover and more momentum or a smaller rear wheel for enhanced playfulness? You decide. If you want to change the combination, we offer the appropriate linkage in our shop. And rest assured, the geometry and ride characteristics remain the same. SWAT BOX: The innovative SWAT™ Box 4.0 integrated into the down tube provides a wind-, weather-, and crash-resistant storage compartment, now even safer and better integrated in the Stumpjumper 15 Alloy.
