PERFECTED KINEMATICS: As the epitome of a trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal impact force management. In 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 nimble steering feel in tight sections, and an incredibly efficient climbing behavior. 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 easy balance even in challenging terrain thanks to plenty of 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 steering angle and bottom bracket height can be changed for the optimal center of gravity or necessary ground clearance.
FORM FOLLOWS FUN: Of course, we can build a frame that is maximally stiff, but that’s 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 offers exactly the stiffness required for trail riding.
WHEEL SIZE: All models with steel spring shock are equipped with wheels of different sizes.
MULLET OR FULL 29ER: Big wheels for better rollover 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 link 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 the first owner is just one example of how we are always there for you.
