{"product_id":"s-works-stumpjumper-15-evo-frameset-fox-float-x-genie-factory","title":"S-Works Stumpjumper 15 EVO Frameset - FOX FLOAT X GENIE Factory","description":"The Stumpjumper 15 is engineered to eliminate trade-offs in trail riding. It delivers the bump-absorbing capability of a larger travel bike while maintaining the short-travel control, playfulness, and efficiency that make trail riding enjoyable. The frameset is highly personalizable, allowing riders to dial in geometry and setup to match their riding style and terrain.\n\nThe breakthrough innovation on this frameset is GENIE shock technology, a patent-pending air spring system that combines the feel and control of a coil spring with the progressive spring rate of an air spring. This dual-stage design provides better bottom-out prevention than a standard air spring while maintaining a tunable, playful platform. GENIE delivers 16.3% better bump force management than traditional air springs, allowing the 145mm rear travel Stumpjumper 15 to absorb impacts comparable to bikes with significantly more travel.\n\nTraction performance is a key strength, with GENIE technology delivering 57% better traction than standard air-sprung shocks by maintaining supple, coil-like performance that keeps the wheel in contact with the ground more consistently. The technology also reduces bottom-outs by 39% compared to standard air springs through its pronounced rising rate in the final 30% of the stroke.\n\nGeometry is optimized for versatility, delivering big bike capability when needed, nimble handling in tight sections, and efficient climbing characteristics. The generous cockpit centers the rider for optimal traction and corner control, while the low bottom bracket, slack head tube angle, and optimized fork offset provide stability in rough terrain. Six distinct geometry settings allow fine-tuning of head angle and bottom bracket height for stability or clearance preferences.\n\nWheel configuration is flexible through aftermarket shock links, allowing riders to choose between 29\" wheels front and rear or mix a 27.5\" rear for a more responsive and playful ride without affecting geometry. SWAT 4.0 internal downtube storage provides smooth, weather-resistant, flush-mounted carrying capacity. The frameset is built with a lightweight FACT 11m carbon chassis and is compatible with electronic drivetrains only.\n\n\u003cdiv data-section-type=\"hero-banner\" data-theme=\"black\" 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=\"black\" 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.
