Specialized Stumpjumper 15 Expert Mountain Bike 2025

The Stumpjumper 15 sets a new benchmark in trail riding, eliminating trade-offs with its ability to handle bumps like a larger bike while maintaining the agility and efficiency of a short-travel design. Featuring GENIE Shock Technology for a lively, bottomless DH feel, it surpasses the traction of the acclaimed "Bike of the Year" Stumpjumper EVO. With extensive personalization options including six-way geometry adjustment, mixed wheel or 29" compatibility, and a tunable spring curve, it caters to every rider's preferences.

GENIE combines the best attributes of coil and air springs, offering supple performance with enhanced bottom-out prevention and tunability. It manages bump forces 16.3% better than traditional air shocks and reduces bottom-outs by 39%, ensuring a smooth ride even during aggressive maneuvers. The bike's honed geometry optimizes stability and maneuverability with features like a low bottom bracket and slack head tube angle, enhancing cornering and traction.

Designed for versatility, the Stumpjumper 15 accommodates different wheel sizes without compromising geometry integrity through aftermarket shock links. SWAT 4.0 provides advanced downtube storage, and the FACT 11m carbon chassis ensures lightweight durability. Equipped with a Ride Dynamics tuned FOX FLOAT Performance Elite shock and FOX FLOAT 36 Performance Elite fork with GRIP X2 damper, it offers precise control over varied terrain. The SRAM GX Eagle T-Type AXS drivetrain and Maven Bronze 4-piston brakes deliver reliable performance, complemented by the adjustable travel PNW LOAM dropper post for on-the-fly adjustments.

Backed by a commitment to durability and customer satisfaction, including lifetime replacement of suspension pivot bearings, the Stumpjumper 15 is compatible exclusively with electronic drivetrains, making it the ultimate choice for discerning riders seeking uncompromising performance and customization options.
