Specialized Stumpjumper 15 Expert 2025 Bike (Gunmetal)

The Stumpjumper 15 Expert's geometry is engineered for versatility, offering the capability of a larger bike when needed, nimbleness in tight sections, and efficient climbing. Its spacious cockpit enhances traction and cornering control, while the low bottom bracket, slack head tube angle, and optimised fork offset ensure stability on rough terrain.

 

The standout innovation on the Stumpjumper 15 is the GENIE air spring technology, which grants every trail rider’s three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable platform for a playful ride. The GENIE technology merges the linear spring rate of a coil spring with the progressive rate of an air spring, avoiding bottom-outs and offering unparalleled tunability. This results in 16.3% better bump force management, making the Stumpjumper 15 feel like a bike with more travel. Extensive testing has shown that it delivers 57% better traction and 39% fewer bottom-outs compared to standard air springs.

 

The Stumpjumper 15 stands out with its unprecedented level of customizability, featuring six distinct geometry settings for fine-tuning performance to match any riding style or terrain. You can adjust the head angle and bottom bracket for increased stability or better clearance. All coil-sprung models come with mixed wheel sizes, but with our aftermarket shock links, you have the option to use large wheels both front and rear or opt for a 27.5” rear wheel for a more responsive and playful ride without affecting the bike’s geometry. Additionally, the SWAT 4.0 system revolutionizes downtube storage, providing the smoothest, most weather-resistant, and flush-mounted system available. Built to endure years of hard riding, our full suspension bikes are supported by unparalleled policies, including a lifetime no-questions-asked replacement of suspension pivot bearings for the original owner, ensuring you’re always ready for the trail.
