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 have the control, playfulness, and efficiency of bikes with minimal suspension travel? Double check. And what about various adjustment options to perfectly tailor the bike to your preferences and riding style? Check, check, check. REFINED KINEMATICS: As the embodiment of a trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal shock management. We have created a balance in anti-squat between the previous model and the Stumpjumper EVO, both of which excelled in ride quality. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike offers big bike virtues on demand, with a light and agile steering feel in tight sections and extremely efficient climbing capabilities. 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 in challenging terrain due to ample stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike according to preferences and terrain. The head angle and bottom bracket height can be modified for the ideal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: While we can create a frame that's extremely stiff, that isn't always the best approach. To become one with the bike, the frame must exhibit a certain level of flex. We designed the M5 aluminum chassis – including the front and rear triangle as well as the connection between them – as a unit that provides the stiffness necessary for trail riding. WHEEL SIZE: All models featuring a steel spring shock come with different wheel sizes. MULLET OR FULL 29ER: Larger wheels for improved rollover and more momentum, or a smaller rear wheel for enhanced playfulness? You have the choice. 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 extra storage space in the down tube of the Stumpjumper 15 – an innovation that originated from us. UNCOMPROMISING AS YOU ARE: Our fully suspended bikes are designed for tough use, standing up to years of hard wear and supported by the best service and policies to keep you on the trail. Our unique lifetime and unrestricted replacement of pivot bearings for original owners is just one example of how we are always here for you.
