The Stumpjumper 15 Pro is here and ready to eliminate any compromises in trail performance. Does it handle rough sections like a big bike? Check. Does it have the control, playfulness, and efficiency of bikes with less travel? Double check. And what about various adjustment options so you can tailor the bike perfectly to your style? Check, check, check. EVEN MORE CAPABLE: Our new GENIE shock technology combines a playful and springy ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROLLED: The Stumpjumper 15 offers better traction properties 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 UNGRANTED: Our latest innovation is GENIE. This air shock technology meets the three greatest desires of our riders: an almost "bottomless" air shock that has 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 during the first 70% of travel 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 springs—with tuning options. Say goodbye to compromises. The future of trail riding starts now. MORE TRACTION: Extensive testing in the lab and on trails has shown that the Stumpjumper 15 with GENIE has 57% better traction properties compared to a conventional air shock. Our new GENIE technology provides the smooth performance of a steel spring, ensuring more ground contact for your rear wheel on average than a standard air shock. Your forces are transmitted better, 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 travel, the damping resistance progressively increases, thus 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 lightweight, nimble steering feel in tight sections and extremely efficient climbing behavior. The spacious central 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 in challenging terrain thanks to plenty of stability.
