PERFECTION OF THE KINEMATICS:

As the quintessential trail bike, it should come as no surprise that the Stumpjumper 15 Alloy Specialized 2025 strikes a perfect balance between efficiency and impact absorption. As for the anti-squat, we sought a balance between the Stumpjumper and Stumpjumper EVO, both with excellent pedaling.

OPTIMIZED GEOMETRY:

The geometry of this bike offers the ability of a big bike when you need it, an agile feel in tighter sections, and a light and efficient behavior on climbs. The generous cockpit puts you in the center of the bike, optimizing traction and control in corners. The low bottom bracket, slack head angle, and optimized fork offset keep it stable in rough terrain.

RIDE YOUR WAY:

The Stumpjumper 15 Alloy Specialized 2025 perfectly integrates reference geometry adjustment, making it the most customizable trail bike in history. Six different geometric adjustments allow you to fine-tune performance for any style on any terrain. The head tube angle and bottom bracket height can be precisely adjusted for stability or clearance.

FORM AND FUN GO HAND IN HAND:

We can make the frame as stiff as we want, but that may not be ideal. To blend with the bike, the frame must meet engineering requirements. We’ve designed the M5 aluminum frame (front, rear, and the connection between them) as a single unit that meets the stiffness target we’ve set for the trail.

WHEEL SIZE:

All coil suspension models come with mixed wheels.

WHEELS FOR EVERYONE:

With our aftermarket shocks, you can choose between big wheels front and rear or mix it up with a 27.5″ rear for a more responsive and playful ride. No matter what you choose, the geometry remains unaffected.

TAKE IT ALL:

The SWAT 4.0 on the Stumpjumper 15 Alloy Specialized 2025 increases storage in the down tube, an innovation we pioneered. It is the most weather-resistant storage system.

MORE RELIABLE THAN YOU:

Our full-suspension bikes are built to be relentless, designed to withstand years of hard riding, and backed by the best support and policies to keep you on the trail. Our unmatched lifetime, no-questions-asked warranty on suspension pivot bearings to the original owner is just one of the ways we’ve got you covered.
