+1, and in my experience Campy was the only mfgr. that made replacement races available, but they offered about 1 cup for every 100 replacement cones so they were never really easy to find. The "dirty" fix (that sometimes worked a charm) was to load the hub up with lapping compound (as used to lap auto valve seats/valves) and the old bearings/cones and spin the axle with an electric drill. Clean ALL the compound out and replace with new cones, balls and grease. As I say, it *sometimes* worked miracles, but could also lap away the hardened layer of the cup and so...YRMV.
