As part of Shimano's 12-speed GRX 820 groupset, the RX822 handles a wide 10-51T cassette range, giving you the low gearing to grind steep unpaved climbs and enough top-end for fast tarmac connectors between them.\u003c\/p\u003e\n\n\u003cp\u003eThe Shadow RD+ mechanism keeps the derailleur quiet and controlled on rough ground. Its integrated chain stabilizer — designed to reduce chain slap and prevent drops on technical sections — can be switched off when conditions don't require it, so you're not adding unnecessary tension on smoother surfaces. It's a practical feature that earns its place on longer mixed-terrain rides where the trail can go from chunder to hardpack without warning.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX RX822 Rear Derailleur SGS Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeeds:\u003c\/strong\u003e 12-speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCassette compatibility:\u003c\/strong\u003e 10-51T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCage length:\u003c\/strong\u003e SGS (long cage)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain stabilizer:\u003c\/strong\u003e Shadow RD+ with on\/off switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43520177438764,"sku":"IRDRX822SGS","price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-grx-rx822-rear-derailleur-sgs-4467430.jpg?v=1771297810","url":"https:\/\/ricycles.com\/products\/shimano-grx-rx822-rear-derailleur-sgs","provider":"RA Cycles","version":"1.0","type":"link"}
