The Stumpjumper 15 Alloy has arrived, ready to eliminate any compromises in trail riding. Does it tackle trail obstacles like a big bike? Check. Does it offer the control, playfulness, and efficiency of bikes with less suspension travel? Double check. And how about various adjustment options to perfectly tailor the 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 force management. We have created a balance in the anti-squat feature of the Stumpjumper 15 Alloy between the predecessor model and the Stumpjumper EVO, both of which had 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 highly efficient climbing abilities. The spacious central cockpit centers 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 due to their 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 head angle and bottom bracket height can be changed for an optimal center of gravity or needed ground clearance. FORM FOLLOWS FUN: While we can certainly create a frame that is extremely stiff, it is not always practical. To become one with the bike, the frame needs to exhibit some flex. We have designed the M5 aluminum chassis – the front and rear end, as well as the connection in between – as a unit that provides just the right stiffness required for trail riding. WHEEL SIZE: All models with steel spring dampers are equipped with wheels of varying sizes. MULLET OR FULL 29ER: Big wheels for better rollover 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 suitable linkage in our shop. And no worries, geometry and suspension characteristics remain the same. ALL INCLUSIVE: SWAT™ provides additional storage in the downtube of the Stumpjumper 15 – an innovation that originated with us. UNFORGIVING AS YOU ARE: Our fully suspended bikes are made for uncompromising use, enduring years of hard wear and supported by the best service and policies, so you can always stay on the trail. Our unique lifetime and unrestricted replacement of pivot bearings for original owners is just one example of how we are always here for you.
