2025 Specialized Stumpjumper 15 Expert

Stumpjumper 15 is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you? Check, check, check.

BREAKTHROUGH CAPABILITY: GENIE Shock Technology combines a poppy, playful ride with a bottomless DH feel.

ULTIMATE CONTROL: Measurably better traction than “Bike of the Year” Stumpjumper EVO.

UNMATCHED PERSONALIZATION: Six-way geometry adjustment, mixed wheel or 29”, tunable spring curve, and more.

GENIE—The Magic Carpet Ride: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology that we invented 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 feel.
