The Stumpjumper 15 Pro is here to eliminate any compromises in trail riding. Does it tackle rough trails 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 the bike to you and your riding style? Check, check, check. EVEN MORE CAPABLE: Our new GENIE damper technology combines a playful and responsive riding experience with the downhill capabilities of enduro bikes. EVEN MORE CONTROLLED: The Stumpjumper 15 has 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. The air damper technology that meets the top three wishes of our riders: an almost "bulletproof" 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 offers the best of both worlds—steel and air springs—plus 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 spring dampers, GENIE in the Stumpjumper 15 makes it feel as if the bike has much more suspension travel. For example, the Stumpjumper 15 with 145 mm in the rear and our enduro with 170 mm both use 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 with GENIE has 57% better traction characteristics compared to a conventional air spring damper. Our new GENIE technology provides the smooth performance of a steel spring, resulting in more rear wheel contact and better power transfer, giving 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 frequency and intensity of potential bottom outs. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike offers big bike virtues on demand, with a nimble steering feel in tight sections and highly efficient climbing capabilities. The spacious cockpit centers riders for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset provide effortless balance in challenging terrain thanks to increased 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. The head angle and bottom bracket height can be altered for the ideal center of gravity or necessary ground clearance. MULLET OR FULL 29ER: Larger wheels for better rollover and more momentum, or a smaller rear wheel for increased playfulness? The choice is yours. If you want to change the combination, we offer compatible linkage options in our shop. And don't worry, geometry and ride characteristics remain the same. SWAT BOX: The ingenious SWAT™ Box 4.0 in the downtube provides the Stumpjumper 15 with a wind-, weather-, and crash-resistant storage compartment, now even safer and better integrated.
