Used Campagnolo Veloce 10 speed RD (short cage). My research tells me this is the circa 2009/2010 model (do correct me if I'm wrong). Selling as its now surplus to my requirements and clearing out unneeded parts at the end of the academic year. The movement of the cage is smooth as far as I can tell, and the jockey wheels still spin fine - the derailleur is in generally good condition. Listed on eBay here: https://www.ebay.co.uk/itm/253687633114?ssPageName=STRK:MESELXT&_trksid=p3984.m1558.l2649. Due to end on Mon 18/6. Feel free to contact me with any questions you may have, and thanks for looking!
