The Stumpjumper 15 Alloy Comp is here and ready to eliminate any compromises in trail performance. Does it tackle bumps on the trail like a big bike? Check. Does it have the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And what about various adjustment options to perfectly tailor your bike to your preferences and riding style? Check, check, check. EVEN MORE CAPABLE: Our new GENIE damper technology combines a playful and springy ride with the downhill capabilities of enduro bikes. EVEN MORE CONTROL: The Stumpjumper 15 Alloy offers better traction than our "Bike of the Year," the Stumpjumper EVO. ENDLESSLY CUSTOMIZABLE: Six different geometry settings, mullet or full 29er configuration, adjustable spring curve, and much more. GENIE LEAVES NO DESIRES UNFULFILLED: Our latest innovation is GENIE. This air damper technology fulfills the top three wishes of our riders: an almost "impermeable" 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 in the first 70% of the travel with the progressive spring rate of an air spring in the last 30%. This maximizes control and prevents bottoming out. GENIE brings together the advantages of both steel and air springs, along with tuning options. Say goodbye to compromises. The future of trail riding starts now. BETTER IMPACT FORCE MANAGEMENT: With 16.3% better impact force management than conventional air-sprung dampers, GENIE ensures that the Stumpy 15 rides as if it has significantly more travel. For example, both the Stumpjumper 15 Alloy with 145 mm rear travel and our enduro bike with 170 mm utilize 101 mm of 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 offers 57% better traction compared to traditional air-sprung dampers. Our new GENIE technology delivers the smooth performance of a steel spring, resulting in increased rear wheel contact compared to a standard air damper. This improves power transfer and gives you more control. LESS BOTTOMING OUT: The harder the hits, the more the "silent reserve" of GENIE reveals its full potential: In the last 30% of the travel, the damping resistance progressively increases – reducing the potential frequency and intensity of bottom outs.
