Specialized Stumpjumper 15

The 2025 Specialized Stumpjumper 15 Comp Full Suspension Mountain Bike is the latest generation of Specialized’s flagship mountain bike. It devours bumps like a big bike but has the control, playfulness and efficiency of a short travel bike.

The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology, invented by Specialized, 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 tuneable “platform” for a playful feel. Extensive field testing proves that Stumpjumper 15 with GENIE delivers 57% better traction than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground a greater percent of the time than a typical air spring would.

The Stumpjumper 15 Comp comes with custom tuned Fox FLOAT rear shock and Fox FLOAT 36 forks. The bike comes with a SRAM Eagle T-Type AXS wireless electronic drivetrain, SRAM Maven Bronze 4-piston brakes and an X-Fusion Manic dropper post.

This bike is perfect for

Mountain bikers who want the latest tech on a bike with some serious heritage. The Stumpjumper 15 has tuneable geometry, custom shocks and the latest electronic gearing.
