Wireless connectivity is integrated directly into the derailleur alongside the system charging port, and an onboard LED indicator keeps you informed of battery status, pairing state, and adjustment mode — so you know exactly where the system stands before and during a ride.\u003c\/p\u003e\n\n\u003ch3\u003eShimano Dura-Ace Di2 9250 Rear Derailleur Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano 12-speed Di2 electronic groupset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax sprocket:\u003c\/strong\u003e 34 teeth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCage length:\u003c\/strong\u003e Single length (accommodates full range)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnectivity:\u003c\/strong\u003e Wireless, with integrated system charging port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicator:\u003c\/strong\u003e Onboard LED for battery, pairing, and adjust mode status\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":43711418499116,"sku":"IRDR9250F","price":930.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-dura-ace-di2-9250-rear-derailleur-6168473.jpg?v=1771297990","url":"https:\/\/ricycles.com\/products\/shimano-dura-ace-di2-9250-rear-derailleur","provider":"RA Cycles","version":"1.0","type":"link"}
