Specialized Stumpjumper 15 Alloy - Blue

The Specialized Stumpjumper 15 Alloy leaves no room for compromise on the trails. Does it glide 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.
CINEMATICS PERFECTION: the Stumpjumper 15 Alloy is the ultimate trail bike, super efficient with excellent shock force management. For the Anti Squat, we sought a balance between the previous versions, Stumpjumper and Stumpjumper EVO, both equipped with exceptional pedaling characteristics.
GEOMETRY TUNED: this bike offers the same capabilities as those with ample travel; it 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 a fully adjustable geometry, the Stumpjumper 15 Alloy is the most customizable trail bike ever. Six different setups allow you to choose the most suitable performance based on your riding style and terrain type. The head angle and bottom bracket height are adjustable to give you a more stable ride feel or with more 'clearance'.
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 structure that offers the necessary stiffness for trail riding needs.
WHEEL SIZES: all coil-spring models have differentiated wheels.
WHEEL CHOICE: with our aftermarket shock links, you can choose to mount large wheels on both the front and rear or opt for a 27.5” rear wheel for a more responsive and playful ride without compromising geometry.
EVERYTHING AT HAND: the SWAT™ Door compartment of the Stumpjumper 15 Alloy, an innovation introduced by Specialized, increases the space inside the downtube.
UNSTOPPABLE LIKE YOU: our full-suspension bikes are ready for anything and designed to withstand years and years of use on all types of trails. Plus, with 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.
