Specialized Stumpjumper 15 FOX Coil Alloy S5 brushed/liquid metal/cast blue model 2025

Specialized Stumpjumper 15 Fox Coil Alloy

The Stumpjumper 15 Alloy is here, ready to erase every compromise in the trail game. Does it soak up bumps on the trail like a big bike? Check. Does it have the control, playfulness, and efficiency of shorter-travel bikes? Double check. And what about the wide range of adjustability so you can perfectly tailor your bike to you and your riding style? Check, check, check.

PERFECTED KINEMATICS: As the epitome of the trail bike, the Stumpjumper 15 Alloy combines efficiency with optimal impact force management. With the anti-squat of the Stumpjumper 15 Alloy, we created a balance between the previous model and the Stumpjumper EVO, as both offered outstanding riding characteristics.

PROGRESSIVE TRAIL GEOMETRY: The geometry of this bike delivers big-bike virtues on demand, offering a feather-light, agile feel in tight sections and incredibly efficient climbing performance. The central, spacious cockpit centers the rider for optimal traction and cornering control. The low bottom bracket, slack head tube angle, and optimized fork offset provide effortless balance and stability, even on challenging terrain.

A FRAME FULL OF POSSIBILITIES: Six individual settings allow riders to perfectly adjust the ergonomics and efficiency of their bike to their preferences and terrain. Head tube angle and bottom bracket height can be changed for the optimal center of gravity or the necessary ground clearance.

FORM FOLLOWS FUN: Of course, we can build a frame to be as stiff as possible, but that's not always practical. To become one with the bike, the frame needs to offer a certain degree of flexibility. We designed the M5 aluminum chassis – front and rear triangles, as well as the connection between them – as a single unit that provides precisely the stiffness required for trail riding.

WHEEL SIZE: All models with steel spring shock absorbers are equipped with different sized wheels.

MULLET OR FULL 29ER: Large wheels for better rollover performance and more momentum, or a smaller rear wheel for more playful handling? The choice is yours. If you'd like to change the combination, we offer the appropriate rocker link in our shop. And don't worry, the geometry and suspension characteristics remain the same.

EVERYTHING INCLUDED: SWAT™ provides additional storage space in the downtube of the Stumpjumper 15 – an innovation that originated with us.

MORE RELIABLE THAN YOU: Our full-suspension bikes are built for relentless use, withstand years of hard riding, and are backed by the best support and guidelines to keep you on the trail. Our unique lifetime, unlimited pivot bearing replacement for original owners is just one example of how we're always there for you.
