The Stumpjumper 15 Alloy is here and ready to eliminate any compromises in trail riding. Does it handle rough trail sections 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 adjustable settings so you can perfectly tailor your bike to your preferences and riding style? Check, check, check.
PERFECTED KINEMATICS: As the epitome of trail bikes, the Stumpjumper 15 Alloy combines efficiency with optimal impact force management. We have created a balance in anti-squat between the previous model and the Stumpjumper EVO, as both delivered excellent riding characteristics.
PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike offers big bike virtues on demand, providing a light and nimble steering feel in tight sections and an incredibly efficient climbing ability. The central, spacious cockpit positions the rider for the best possible traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset ensure easy balance even in challenging terrain, thanks to increased 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. Steering angle and bottom bracket height can be modified for optimal center of gravity or necessary ground clearance.
FORM FOLLOWS FUN: While we can build a frame to be incredibly stiff, that’s not always the best approach. To truly connect with the bike, the frame must show some flexibility. We designed the M5 aluminum chassis—front and rear sections and the connection between them—as a unit that provides just the right stiffness for trail riding.
WHEEL SIZE: All models with coil shock are equipped with differently sized wheels.
MULLET OR FULL 29ER: Large wheels for improved rollover performance 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, geometry and suspension characteristics remain unchanged.
ALL INCLUSIVE: SWAT™ provides additional storage in the downtube of the Stumpjumper 15—an innovation that we pioneered.
UNFORGIVINGER THAN YOU: Our full-suspension bikes are built for unforgiving use, withstand years of hard wear, and are backed by the best support and policies to keep you on the trail. Our unique lifetime and unrestricted replacement of swing bearings for original owners is just one example of our commitment to being there for you.
