Worthy of most show bikes, these don't pop in this nice of condition often.  The only cosmetic wear I see the odd extra polished looking section of finish near the a\/b knob these get, and a light scuff on the lower left knuckle.  Pivots\/springs are smooth and tight.  \u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eAs for those pulleys.  The upper pulley is broken, and the lower pulley shows two very worn teeth.  I could presume that a previous owner harvested the pulleys from this and put on some worn once as a place holder, as their conditions really don't match how almost pristine the derailleur is otherwise.  For a show only and not ridden bicycle, this would be just fine until you find replacements as you don't really see the pulleys from the front of the derailleur.\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e:\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eShort cage\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eMax Cog: A setting: 27t  B setting: 32t\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eModel: C010-SM\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eMade 1988 to 1991\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":53188564320396,"sku":"9465","price":99.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5144\/9740\/files\/vintage_campagnolo_c_record_chorus_Gran_sport_nr_sr_15051__11950.1585970151.1280.1280_2b4fa9c8-2b0e-49b9-80a8-ce9189018e80.jpg?v=1792353264","url":"https:\/\/swooncycles.com\/products\/campagnolo-chorus-rear-derailleur-8-speed-rare-a-b-switch-near-mint-needs-pulleys","provider":"Swoon Cycles (Bike ReCyclery)","version":"1.0","type":"link"}
