Harvey, I guess I was a little unclear in my post. I'm referring to the part being stamped or machined, in this case the races that are inserted into the hub shells, not the actual surface that the balls ride on. Of course the Record hub's races are ground after they are machined... would you expect anything less that the best from Tullio?
