The Stumpjumper 15 Alloy has arrived and is ready to eliminate any compromises in the trail game. Does it tackle obstacles on the trail like a big bike? Yes. Does it have the control, playfulness, and efficiency of bikes with less travel? Absolutely. And what about various adjustable settings to perfectly tailor the bike to your preferences and riding style? Yes, yes, yes. REFINED KINEMATICS: As the epitome of a trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal shock absorption management. We have created a balance in the anti-squat of the Stumpjumper 15 Alloy between the predecessor model and the Stumpjumper EVO, both of which feature excellent riding characteristics. PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big bike virtues on demand, providing a lightweight and agile handling feel in tight sections and impressive climbing efficiency. The spacious, central cockpit centers the rider for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset offer effortless balance even in challenging terrain, thanks to enhanced 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 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 truly connect with the bike, the frame must exhibit a degree of compliance. We designed the M5 aluminum chassis - the front and rear ends and the connection in between - as a unit that provides just the right stiffness needed for trail riding. WHEEL SIZE: All models with steel spring shock absorbers come equipped with wheels of varying sizes. MULLET OR FULL 29ER: Big wheels for better rollover and more momentum or a smaller rear wheel for playful handling? You have the choice. If you want to change the combination, we offer the suitable rocker link in our shop. And don’t worry, the geometry and suspension characteristics will remain the same. ALL INCLUDED: SWAT™ offers additional storage in the down tube of the Stumpjumper 15 - an innovation that originated from us. UNFORGIVING AS YOU: Our full-suspension bikes are designed for rigorous use, enduring years of hard wear, and are supported by the best warranty and policies to keep you on the trail. Our unique lifetime and unrestricted replacement of the pivot bearings for original owners is just one example of how we are always here for you.
