The Stumpjumper 15 Alloy is here and ready to eliminate any compromises in the trail game. Does it tackle trail obstacles like a big bike? Check. Does it offer the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And what about various adjustment options so you can perfectly tailor the 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 force management. For the Stumpjumper 15 Alloy's anti-squat, we have created a balance between the previous model and the Stumpjumper EVO, as both provided excellent riding characteristics. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike offers big bike virtues on demand, with a lightweight and agile steering feel in tight sections and incredibly efficient climbing abilities. The central, spacious cockpit centers the rider for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset provide effortless balance even in challenging terrain, thanks to great stability. A FRAME FULL OF POSSIBILITIES: Six individual adjustments allow riders to perfectly fine-tune the ergonomics and efficiency of their bike according to preferences and terrain. Steering angle and bottom bracket height can be altered for the ideal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: Of course, we can build a frame with maximum stiffness, but that isn’t always practical. To become one with the bike, the frame must exhibit some flexibility. We designed the M5 aluminum chassis – front and rear triangle along with the linkage – as a unit that offers just the right amount of stiffness required for trail riding. WHEEL SIZE: All models with coil spring suspension are equipped with different wheel sizes. MULLET OR FULL 29ER: Large wheels for better rollover capability and more momentum, or a smaller rear wheel for increased 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 remain the same. ALL-INCLUSIVE: SWAT™ provides additional storage space in the down tube of the Stumpjumper 15 – an innovation that originated with us. UNCOMPROMISING: Our full-suspension bikes are built for relentless use, enduring years of tough conditions, supported by the best service and policies so you can always stay on the trail. Our unique lifetime and unrestricted replacement of the linkage bearings for the original owners is just one example of how we are here for you.
