The Stumpjumper 15 Expert is here and ready to eliminate any compromises in trail riding. Does it tackle rough sections like a big bike? Check. Does it offer the control, playfulness, and efficiency of bikes with less suspension? Double check. And what about adjustable settings 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, springy ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROL: The Stumpjumper 15 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 WISHES UNFULFILLED: Our latest innovation, GENIE, features air damper technology that fulfills the three biggest wishes of our riders: an almost "indestructible" 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 stroke with the progressive spring rate of an air spring in the last 30%. This maximizes control and prevents bottom-outs. GENIE offers the best of both worlds – steel and air spring – 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 traditional air-sprung dampers, GENIE in the Stumpy 15 makes the bike feel as if it has much more travel. For example, the Stumpjumper 15, with 145 mm at 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 trails has shown that the Stumpjumper 15 with GENIE has 57% better traction characteristics compared to a conventional air-sprung damper. Our new GENIE technology provides the smooth performance of a steel spring, ensuring more contact with the ground than a regular air-sprung damper. Your forces are transmitted more effectively, giving you more control. LESS BOTTOM-OUTS: The harder the hits; the more the "silent reserve" of GENIE reveals its full potential: In the last 30% of the suspension travel, the damping resistance progressively increases - thereby reducing the potential bottom-out 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 capabilities. The central, spacious cockpit centers riders 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 due to high stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the bike's ergonomics and efficiency according to preferences and terrain. The steering angle and bottom bracket height can be altered for optimal center of gravity or necessary ground clearance. MULLET OR FULL 29ER: Large wheels for better rollover and more momentum, or a smaller rear wheel for added playfulness? The choice is yours. If you want to change the combination, we offer the suitable linkage in our shop. And don’t worry, geometry and suspension characteristics remain unchanged. SWAT BOX: The ingenious SWAT™ Box 4.0 in the down tube provides the Stumpjumper 15 with a wind-, weather-, and crash-proof storage compartment, now even safer and better integrated.
