It masterfully blends the capability to handle rough terrain like a long-travel bike with the agility, playfulness, and efficiency of a short-travel bike. A key innovation is GENIE, Specialized's patent-pending air spring technology, offering riders three core benefits: the feel and control of a coil spring, superior bottom-out resistance compared to standard air springs, and adjustable tuning for a playful ride. Field testing confirms that the Stumpjumper 15 with GENIE achieves 57% better traction than typical air-sprung shocks due to its supple, coil-like performance that maintains better wheel-to-ground contact.
This model is equipped with a custom-tuned Fox FLOAT rear shock and Fox FLOAT 36 forks. The bike features a SRAM Eagle T-Type AXS wireless electronic drivetrain for smooth and precise shifting, and powerful SRAM Maven Bronze 4-piston brakes for reliable stopping power. The frame is constructed from lightweight FACT 11m carbon, and it rolls on robust Specialized alloy wheels with sealed cartridge bearings. The X-Fusion Manic dropper post ensures reliable and infinite adjustability.

- Frame: FACT 11m carbon chassis and rear-end, Trail Geometry, SWAT™ Door integration, head tube angle adjustment, threaded BB, internal cable routing, 12x148mm dropouts, 145mm travel.
