The result is Shimano GRX components, representing Shimano's first component group specifically developed for gravel and rough road cycling. Shimano GRX stands out from other components with its gravel-specific ergonomics, optimized gear ratios, robust reliability, and a quiet and stable drivetrain. The components are available in both mechanical and Di2\/electronic versions and can be used with Shimano's existing chains\/cassettes (XT\/SLX\/Deore\/Ultegra\/105\/Tiagra).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eGRX rear derailleurs come in short-cage and medium-cage versions. They feature Shimano's Shadow RD+ technology, just like their mountain bike rear derailleurs. With a clutch function that ensures less noise and chain slap. If you use a cassette with 11-30\/32T, a short-cage must be used, and if you have a cassette that goes all the way up to 40\/42T, a medium-cage is required.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eMechanical\/Di2 (electronic): Mechanical\u003c\/span\u003e  \u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eMaterials: Aluminum, steel\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eShort\/medium cage: Medium cage\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eLargest sprocket cassette: 11T\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eTeeth: 11T\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eTotal capacity: 31T\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eNumber of gears: 11-speed\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan face=\"Tahoma\" size=\"2\" style=\"font-family: Tahoma; font-size: small;\"\u003eSmallest sprocket cassette: 42T  \u003c\/span\u003e\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":40383824953403,"sku":"IRDRX812","price":1299.0,"currency_code":"NOK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0376\/1471\/4939\/products\/shimano-grx-rd-rx812-bakgir-258.jpg?v=1705031738","url":"https:\/\/zensykkel.no\/en\/products\/shimano-grx-rd-rx812","provider":"Zen Sykkel","version":"1.0","type":"link"}
