Specialized S-Works Stumpjumper 15 Frameset

The Stumpjumper 15 carries the legacy of one of the famous names in mountain biking. Labelled as the ultimate trail bike, the new Stumpjumper handles bumps like a heavyweight, ensuring a smooth ride. It offers the agility, control, and efficiency of a short-travel bike, making it incredibly versatile. The bike’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 optimized 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.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.

We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
