{"product_id":"stumpjumper-15-evo-expert-sram-gx-axs-fox-performance-elite","title":"Stumpjumper 15 EVO Expert - SRAM GX AXS, FOX Performance Elite","description":"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.\n\nThe centerpiece of the Stumpjumper 15 is GENIE, a patent-pending air spring technology 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 the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable platform for a playful ride.\n\nGENIE delivers measurably superior performance compared to traditional air-sprung shocks. The technology provides 16.3% better bump force management, allowing the 145mm rear travel Stumpjumper 15 to absorb bumps as effectively as a 170mm travel enduro bike. Field testing demonstrates 57% better traction than a standard air-sprung shock because the supple, coil-like performance keeps the wheel in contact with the ground more consistently. Additionally, GENIE reduces bottom-outs by 39% compared to standard air springs through its two-stage rising rate in the final 30% of the stroke.\n\nThe 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 in rough terrain.\n\nThe Stumpjumper 15 features six distinct geometry settings for unmatched personalization. Head angle and bottom bracket height can be fine-tuned for stability or clearance. With aftermarket shock links, riders can choose between 29\" wheels front and rear or mix a 27.5\" rear for a more responsive and playful ride without affecting geometry.\n\nSWAT 4.0 provides integrated downtube storage with smooth operation and weather resistance. The bike is built with a lightweight FACT 11m carbon chassis and rear-end, paired with a Ride Dynamics tuned FOX FLOAT X Performance Elite shock featuring Specialized GENIE technology. The FOX FLOAT 36 Performance Elite fork with GRIP X2 damper provides supportive, tunable suspension. The drivetrain uses a smooth and precise SRAM GX Eagle T-Type AXS system with powerful SRAM Maven Silver 4-piston brakes. An adjustable travel PNW LOAM dropper post completes the build.\n\nSpecialized backs the bike with a lifetime, no-questions-asked replacement of suspension pivot bearings to the original owner, reflecting confidence in durability and long-term reliability.\n\n\u003cdiv data-section-type=\"hero-banner\" data-theme=\"white\" data-align-h=\"left\" data-align-v=\"center\" data-content-max-width=\"800\"\u003e\r\n\u003ch3\u003eAll You Need To Know About Stumpjumper 15 EVO\u003c\/h3\u003e\r\n\u003cimg src=\"https:\/\/assets.specialized.com\/i\/specialized\/harookz-23-1761?fmt=auto\u0026amp;w=1200\u0026amp;q=80\" alt=\"All You Need To Know About Stumpjumper 15 EVO\" style=\"width:100%;height:auto;\"\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv data-section-type=\"features-triple\" data-theme=\"white\" data-text-align=\"left\"\u003e\r\n\u003cdiv data-section-type=\"feature\"\u003e\r\n\u003ch3\u003eGENIE Grants Every Trail Rider’s Wishes\u003c\/h3\u003e\r\n\u003cp\u003eThis game-changing, patent-pending air spring technology that we invented grants every trail rider three wishes: feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable “platform” for a playful feel.\u003c\/p\u003e\r\n\u003cimg src=\"https:\/\/assets.specialized.com\/i\/specialized\/MTB-4003_Stumpjumper-15_W-GENIE_Article-Component_02_IMG-01_1?fmt=auto\u0026amp;w=1200\u0026amp;q=80\" alt=\"GENIE Grants Every Trail Rider’s Wishes\" style=\"width:100%;height:auto;\"\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv data-section-type=\"feature\"\u003e\r\n\u003ch3\u003eWhat’s Inside GENIE?\u003c\/h3\u003e\r\n\u003cp\u003eCheck out how GENIE 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 to reduce bottom-outs.
