Running a 12-speed drivetrain, it handles cassettes up to 45T, giving you the low gearing to climb technical gravel without compromising cadence on the flats.\u003c\/p\u003e\n\n\u003cp\u003eThe integrated chain stabilizer is where this derailleur earns its keep off-road. It suppresses chain slap and reduces the risk of chain drop on rough surfaces — and when the trail smooths out, you can switch it off. The system is designed to be lighter and more mechanically efficient than roller-type chain retention devices, keeping the overall drivetrain feel clean and direct.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX RX822 Rear Derailleur GS 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\u003eMax sprocket:\u003c\/strong\u003e 45T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCage length:\u003c\/strong\u003e GS (medium cage)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain stabilizer:\u003c\/strong\u003e Switchable on\/off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43520177045548,"sku":"IRDRX822GS","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-gs-4497094.jpg?v=1771297811","url":"https:\/\/ricycles.com\/products\/shimano-grx-rx822-rear-derailleur-gs","provider":"RA Cycles","version":"1.0","type":"link"}
