The Stumpjumper 15 Alloy has arrived, ready to eliminate any compromises in trail performance. Does it absorb trail bumps like a big bike? Check. Does it possess the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And how about various adjustment options to perfectly tailor your bike to your needs and 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. We’ve struck a balance between the previous model and the Stumpjumper EVO in its anti-squat, both of which offered excellent riding characteristics. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike brings big bike virtues when needed, offering a light and agile steering feel in tight sections and exceptionally efficient climbing abilities. The spacious central cockpit centers the rider for optimal traction and cornering control. With a low bottom bracket, slack head tube angle, and optimized fork offset, balance in challenging terrain is easy, providing ample stability. A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike according to their preferences and the terrain. The head angle and bottom bracket height can be altered for optimal center of gravity or necessary ground clearance. FORM FOLLOWS FUN: While we can build a frame with maximum stiffness, that’s not always practical. To truly connect with the bike, the frame must demonstrate some give. We designed the M5 aluminum chassis – the front and rear triangle along with the connection in between – as a single unit that provides the stiffness needed for trail riding. WHEEL SIZE: All models with steel spring shocks feature wheels of varying sizes. MULLET OR FULL 29ER: Choose larger wheels for improved rollover capability and more momentum or a smaller rear wheel for greater playfulness. The option to change the combination is available with compatible linkages in our shop. And don’t worry, geometry and suspension characteristics remain consistent. ALL INCLUDED: SWAT™ provides additional storage in the down tube of the Stumpjumper 15 – an innovation we pioneered. UNFORGIVING AS YOU: Our fully suspended bikes are designed for tough use, standing up to years of hard strain and supported by the best service and policies, ensuring you always stay on the trail. Our unique lifetime unlimited replacement of pivot bearings for original owners exemplifies our commitment to you.
