The Stumpjumper 15 Expert is here and ready to eliminate any compromises in the trail game. Can it handle bumps on the trail like a big bike? Check. Does it provide the control, playfulness, and efficiency of bikes with minimal 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 jumping ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROLLABLE: The Stumpjumper 15 has 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 DOES NOT DISAPPOINT: Our latest innovation, GENIE, is an air damper technology that fulfills the top three wishes of our riders: an almost "bulletproof" air damper 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 travel with the progressive spring rate of an air spring in the final 30%. This maximizes control and prevents bottoming out. 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 FORCE MANAGEMENT: With 16.3% better impact force management than traditional air-sprung dampers, GENIE in the Stumpjumper 15 makes the bike feel like it has much more travel. For example, both the Stumpjumper 15 with 145 mm in the rear and our Enduro with 170 mm utilize 101 mm of travel to absorb an impact force of 1080 N. MORE TRACTION: Comprehensive lab and trail tests have shown that the Stumpjumper 15 with GENIE offers 57% better traction characteristics compared to a conventional air-sprung damper. Our new GENIE technology provides you with the smooth performance of a steel spring, leading to more rear wheel contact than a standard air damper. Your forces are transmitted better, giving you more control. FEWER BOTTOM-OUTS: The harder the impacts, the more the "silent reserve" of GENIE shows its full potential: in the last 30% of the travel, the damping resistance increases progressively, thus reducing potential bottoming frequency and intensity. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, a lightweight and agile steering feel in tight sections, and extremely efficient climbing behavior. The central, generous cockpit centers the rider for optimal traction and cornering control. The low bottom bracket, flat head tube angle, and optimized fork offset provide uncomplicated balance and stability in challenging terrain. A FRAME FULL OF OPTIONS: Six individual settings allow the rider to perfectly adjust the ergonomics and efficiency of the bike according to preferences and terrain. Head angle and bottom bracket height can be altered for optimal center of gravity or needed ground clearance. MULLET OR FULL 29ER: Larger wheels for better rollover and more momentum or a smaller rear wheel for more playfulness? You have the choice. If you want to change the combination, we offer the appropriate linkage in our shop. And don't worry, geometry and suspension 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-proof storage compartment, now even safer and better integrated.
