The Stumpjumper 15 Alloy is here and ready to eliminate any compromises in the trail game. Does it absorb bumps on the trail like a big bike? Check. Does it have the control, playfulness, and efficiency of bikes with minimal travel? Double check. And what about various adjustment options to perfectly tailor your bike to you and your riding style? Check, check, check. REFINED KINEMATICS: As the epitome of a trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal impact management. We have created a balance in the anti-squat between the previous 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, with a light and nimble steering feel in tight sections and remarkably efficient climbing abilities. The central, spacious cockpit helps to center 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 significant stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike based on preferences and terrain. The steering angle and bottom bracket height can be modified for optimal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: While we can certainly build a frame to be maximally stiff, it's not always practical. To truly connect with the bike, the frame must exhibit a certain degree of flex. We designed the M5 aluminum chassis - front and rear assembly along with the connections in between - as a unit that provides just the right stiffness needed for trail riding. WHEEL SIZE: All models with coil spring suspension come equipped with different wheel sizes. MULLET OR FULL 29ER: Larger wheels provide better rollover and more momentum, or a smaller rear wheel for more playfulness? It's your choice. If you want to change the combination, we offer the appropriate link in our shop. And don't worry; the geometry and handling characteristics remain the same. ALL INCLUDED: SWAT™ provides additional storage in the downtube of the Stumpjumper 15—a feature that originated with us. UNFORGIVING AS YOU: Our full-suspension bikes are built for relentless use, standing up to years of harsh conditions, supported by the best service and policies to keep you on the trail. Our unique lifetime and unrestricted replacement of pivot bearings for the original owners is just one example of our commitment to you.
