Specialized Stumpjumper 15 Alloy - Grey

The Specialized Stumpjumper 15 Alloy leaves no room for compromise on the trails. It glides over obstacles like a bike with ample travel? Of course! Is it precise, playful, and efficient like a bike with reduced travel? Certainly. Can it be customized to fit the needs of every rider? Absolutely. PERFECTED KINEMATICS: the Stumpjumper 15 Alloy is the ultimate trail bike, super efficient with excellent impact force management. For Anti Squat, we sought a balance between the previous versions, Stumpjumper and Stumpjumper EVO, both equipped with exceptional pedaling characteristics. TUNED GEOMETRY: this bike offers the same capabilities as those with ample travel, is agile on tighter sections, and super efficient and energetic uphill. The generous cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, open head angle, and optimized fork offset improve stability on more technical terrain. CUSTOMIZABLE SETUP: with fully adjustable geometry, the Stumpjumper 15 Alloy is the most customizable trail bike ever. Six different setups allow you to choose the performance best suited to your riding style and terrain type. The head angle and bottom bracket height are adjustable to give you a more stable or 'looser' ride feel. FUN BEFORE FORM: the frame can be more or less stiff, but not too stiff. To become one with the bike, it must have a certain degree of flexibility. We designed the M5 Alloy frame by combining the front triangle, rear triangle, and link into a single unit that provides the necessary stiffness for trail riding demands. WHEEL SIZES: all coil spring models have differentiated wheels. WHEEL CHOICE: with our aftermarket shock links, you can choose to mount larger wheels both front and rear or opt for a 27.5” rear wheel for a more responsive and playful ride, without compromising geometry. EVERYTHING WITHIN REACH: the SWAT™ Door compartment of the Stumpjumper 15 Alloy, an innovation introduced by Specialized, increases the space inside the down tube. UNSTOPPABLE LIKE YOU: our dual-suspension bikes are ready for anything and designed to withstand years and years of use on all types of trails. Plus, thanks to our lifetime bearing supply policy for the rear triangle to the original purchaser, you can enjoy the trails even longer. Yes, we thought of everything.
