The Stumpjumper 15 Alloy leaves no room for compromise on the trails. Does it fly over obstacles like a bike with long travel? Of course! Is it precise, playful, and efficient like a bike with short travel? Absolutely. Can it be customized to suit the needs of any rider? Definitely yes.

Perfected Kinematics

The Stumpjumper 15 Alloy is the ultimate trail bike, super efficient, and with excellent shock force management. For the Anti-Squat, we sought a balance between the previous versions, Stumpjumper and Stumpjumper EVO, both offering exceptional pedaling characteristics.

Tuned Geometry

This bike offers the same capabilities as those with long travel; it’s agile on narrow sections and super efficient and energetic uphill. The generous cockpit centers you on the bike, optimizing traction and control in corners. The low bottom bracket, open head angle, and optimized fork offset improve stability on 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 best performance based on your riding style and terrain type. The head angle and bottom bracket height are adjustable to provide a more stable or "higher" ride feel.

Fun Comes Before Form

The frame can be stiffer or more flexible, 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 provides the rigidity necessary for trail riding.

Wheel Sizes

All spring models have differentiated wheels.

Wheel Choice

With our aftermarket shock links, you can choose to mount large 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 space inside the downtube.

As Tireless As You

Our full-suspension bikes are ready for anything and designed to withstand years of use on all kinds of trails. Additionally, thanks to our lifetime bearing supply policy for the rear triangle to the original owner, you’ll be able to enjoy the trails for even longer. Yes, we’ve thought of everything.
