The Stumpjumper 15 Alloy is here and ready to eliminate any compromises in trail riding. Does it handle rough terrain like a big bike? Check. Does it possess the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And what about various adjustment options, allowing you to tailor your bike to your preferences and riding style? Check, check, check. PERFECTED KINEMATICS: As the epitome of a trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal impact management. In terms of anti-squat, we have created a balance between the previous model and the Stumpjumper EVO, as both offered excellent riding characteristics. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, with a light and agile steering feel in tight sections and exceptional climbing efficiency. The spacious central cockpit positions the rider for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset provide effortless balance in challenging terrain thanks to enhanced stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to fine-tune the ergonomics and efficiency of their bike according to their preferences and the terrain. The head angle and bottom bracket height can be adjusted for optimal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: Of course, we can build a frame that is maximally stiff, but that isn't always practical. To achieve a true connection with the bike, the frame needs to exhibit some flex. We designed the M5 aluminum chassis—front and rear and the connection between them—as a unit that provides the perfect rigidity required for trail riding. WHEEL SIZE: All models equipped with a coil shock come with differently sized wheels. MULLET OR FULL 29ER: Large wheels for better rollover and more momentum, or a smaller rear wheel for enhanced playfulness? The choice is yours. If you want to change the combination, we offer the appropriate link in our shop. And don’t worry, the geometry and suspension characteristics will remain the same. ALL INCLUDED: SWAT™ provides the Stumpjumper 15 with additional storage in the downtube—a groundbreaking innovation that originated with us. UNFORGIVING AS YOU: Our full-suspension bikes are built for relentless use, enduring years of rigorous demands, and are supported by the best service and policies to ensure you stay on the trail. Our unique lifetime and unrestricted replacement of pivot bearings for first owners is just one example of how we are always here for you.
