Specialized Stumpjumper 15 Pro Mountain Bike 2025
The Stumpjumper 15 sets a new standard in trail riding, eliminating compromises with its ability to handle bumps like a larger bike while maintaining the control and playfulness of a short-travel design. Featuring GENIE Shock Technology for a poppy, bottomless DH feel, it offers superior traction compared to the "Bike of the Year" Stumpjumper EVO. With six-way geometry adjustment, mixed wheel or 29" options, and a tunable spring curve, it delivers unmatched personalization.
GENIE integrates the best of coil and air springs, providing a supple, coil-like feel with improved bottom-out prevention and tunability. It manages bump forces 16.3% better than traditional air shocks and reduces bottom-outs by 39%. The bike's honed geometry ensures stability and agility, featuring a low bottom bracket and slack head tube angle for confident handling in rough terrain.
Designed for versatility, the Stumpjumper 15 allows seamless integration of different wheel sizes with aftermarket shock links, maintaining geometry integrity. It includes SWAT 4.0 for enhanced downtube storage and a lightweight FACT 11m carbon chassis and rear-end. Equipped with Ride Dynamics tuned FOX FLOAT Factory shock and FOX FLOAT 36 Factory fork, it offers precise control. The SRAM XO Eagle T-Type AXS drivetrain and Maven Silver 4-piston brakes provide reliable performance, complemented by the Bike Yoke Revive Max dropper post for quick adjustments.
Backed by a commitment to durability and customer support, including lifetime replacement of suspension pivot bearings, the Stumpjumper 15 is compatible exclusively with electronic drivetrains, making it a top choice for discerning riders seeking ultimate performance and customization.
