Stumpjumper 15 EVO Comp - SRAM S-1000 AXS, FOX Rhythm

The Stumpjumper 15 EVO is designed to eliminate trade-offs in trail riding. It delivers the bump-absorbing capability of a larger bike while maintaining short-travel control, playfulness, and climbing efficiency. The bike offers extensive personalization options to tailor the ride to individual preferences. The breakthrough innovation on this bike is GENIE Shock Technology, a patent-pending air spring system that combines the control-enhancing linear spring rate of a coil spring through the bump zone with the progressive spring rate of an air spring at the end of the stroke. This hybrid approach provides better bottom-out prevention than a standard air spring while maintaining tunability for a playful feel. GENIE technology delivers measurably superior performance compared to traditional air-sprung shocks. The Stumpjumper 15 manages bump forces 16.3% better than a traditional air spring, produces 57% better traction by keeping the wheel in contact with the ground longer, and experiences 39% fewer bottom-outs during big hits due to its two-stage rising rate in the final 30% of the stroke. The geometry is carefully honed to deliver big bike capability when needed, nimble handling in tight sections, and efficient climbing. The generous cockpit centers the rider for optimized traction and corner control, while the low bottom bracket, slack head tube angle, and optimized fork offset maintain stability on rough terrain. The Stumpjumper 15 features six distinct geometry settings for unmatched personalization. Head angle and bottom bracket height can be fine-tuned for stability or clearance. Wheel choice is flexible—you can run big wheels front and rear or mix a 27.5" rear for a more responsive and playful ride using aftermarket shock links, with geometry remaining unaffected. SWAT 4.0 downtube storage provides smooth operation and weather resistance with a flush-mounted design. The bike is built with a lightweight FACT 11m carbon chassis and rear-end, robust Specialized alloy wheels with sealed cartridge bearings, and a FOX FLOAT 36 Rhythm fork with GRIP damper. Shifting is handled by a SRAM Eagle T-Type AXS drivetrain, while braking power comes from SRAM Maven Bronze 4-piston brakes. An X-Fusion Manic dropper post provides reliable adjustability. Specialized backs this bike with a lifetime, no-questions-asked replacement of suspension pivot bearings to the original owner, reflecting confidence in its durability and design.
