The Stumpjumper 15 Expert is here, ready to eliminate any compromises in the trail game. Does it handle rough terrain like a big bike? Yes. Does it offer the control, playfulness, and efficiency of bikes with less suspension travel? Absolutely. And what about various adjustment options, allowing you to perfectly tune your bike to your riding style? Yes, yes, and yes. EVEN MORE CAPABLE: Our new GENIE damper technology combines a playful and bouncy ride feel with the downhill capabilities of enduro bikes. EVEN MORE CONTROLABLE: The Stumpjumper 15 boasts better traction properties 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 LEAVES NO WISH UNFULFILLED: Our latest innovation is GENIE. This air damper technology fulfills the three biggest desires 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 bottom-outs. GENIE offers the best of both worlds – steel and air spring – plus tuning options. Say goodbye to compromises. The future of trail riding begins now.
