This rear derailleur is compatible with cassettes that have a 42T max low  sprocket.

This leads to  quieter shifting and less chain slap as your bike vibrates. The RX815 Di2 Rear  Derailleur takes some qualities from their mountain bike components. It has a  low profile and is compact and stays tight against the frame to avoid damage in  the event of a crash. The Shimano GRX RX815 Di2 Rear Derailleur is a smooth and  reliable component that will enhance any off-road ride. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e 1x or 2x drivetrains; 11-speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSprockets:\u003c\/strong\u003e Top: 11T; Low: Max 34T\/Min 30T; Total  Capacity: 38T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43583181324332,"sku":"IRDRX815","price":360.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/40484.jpg?v=1753477382","url":"https:\/\/racycles.com\/pt\/products\/shimano-grx-rd-rx815-di2-rear-derailleur","provider":"RA Cycles","version":"1.0","type":"link"}
