The Stumpjumper 15 Alloy is here and ready to eliminate any compromises in the trail game. Does it swallow chunks on the trail like a big bike? Check. Does it have the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And what about various adjustment options so you can perfectly tailor your bike to yourself and your 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 anti-squat of the Stumpjumper 15 Alloy, we have created a balance between the predecessor model and the Stumpjumper EVO, as both brought excellent riding characteristics. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, a feather-light agile steering feel in tight sections, and an incredibly efficient climbing behavior. The central, spacious cockpit centers the rider for the best possible 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. The steering angle and bottom bracket height can be changed for optimal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: Of course, we can build a frame to be maximally stiff, but that is not always sensible. To become one with the bike, the frame must exhibit a certain degree of compliance. We designed the M5 aluminum chassis – front and rear triangle as well as the connection in between – as a unit that provides exactly the stiffness required for trail riding. WHEEL SIZE: All models with steel spring shock are equipped with differently sized wheels. MULLET OR FULL 29ER: Big wheels for better rollover behavior and more momentum or a smaller rear wheel for more playfulness? You have the choice. If you want to change the combination; we offer the appropriate linkage in our shop. And don't worry, geometry and suspension characteristics remain the same. ALL INCLUDED: SWAT™ provides additional storage in the downtube of the Stumpjumper 15 – an innovation that originated with us. UNFORGIVINGER THAN YOU: Our full-suspension bikes are made for unforgiving use, withstand years of hard wear, and are supported by the best support and policies; so you can always stay on the trail. Our unique lifetime and unrestricted replacement of the pivot bearings for original owners is just one example of how we are always there for you.
