I have had four pairs of Normandy Competition hubs, and on three of them the rear unit had pitted bearing surfaces (front units always good). One time I monkeyed around trying to fit cones from other hubs, but nothing I had worked. A good short-term solution is to just ride the pitted hub for a while. The Normandy Sport is supposedly a step down in quality, but there are lots of them around, and I've actually had better luck with the cones and cups. Maillard 700 is very nice, I would rate it about even with Campagnolo Record.
