The Stumpjumper 15 Alloy Comp is ready to impress in the trail game. Does it tackle challenges like a big bike? Yes. Does it have the control, playfulness, and efficiency of bikes with less travel? Absolutely. And does it offer customization options for individual riding styles? Definitely. EVEN MORE COMPETENT: Our new GENIE damping technology combines agile handling with the downhill capabilities of enduro bikes. EVEN MORE CONTROL: The Stumpjumper 15 Alloy offers better traction characteristics than our award-winning Stumpjumper EVO. VERSATILE ADJUSTABILITY: Six geometry settings, mullet or full 29er, adjustable spring curve, and more. GENIE MEETS ALL DESIRES: Our latest innovation, GENIE, offers an incredibly powerful air shock with fine-tuning like a coil shock. THE BEST OF BOTH WORLDS: GENIE combines the linear spring rate of a coil shock with the progressive rate of an air shock. This maximizes control and avoids bottom-outs. No more compromises. IMPROVED SUSPENSION PERFORMANCE: With a 16.3% improvement in shock absorption, GENIE ensures that the bike provides more travel. For example, the Stumpjumper 15 Alloy only uses 101mm of travel to absorb a force of 1080N. MORE TRACTION: Tests show that the Stumpjumper 15 Alloy with GENIE has 57% better traction than conventional air shocks. FEWER BOTTOM-OUTS: Strong shocks are met with increased damping resistance in the final 30% of the travel thanks to GENIE. PROGRESSIVE TRAIL GEOMETRY: The geometry provides agile handling and efficient climbing. Central riding position for optimal traction and control. A lower bottom bracket and flatter head tube angle provide stability. A FRAME FULL OF OPTIONS: Six settings to tailor ergonomics and efficiency to preferences and terrain. Changes to head angle and bottom bracket height are possible. MULLET OR FULL 29ER: Large wheels for better rolling or a smaller rear wheel for more playfulness. Adjustments are possible with the appropriate linkage. SWAT BOX: The SWAT™ Box 4.0 in the downtube provides a secure, weather-protected storage compartment.
