Does anyone have > facts on this? (cut) Chuck responded: 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?
Well, Chuck, I realize that you are a bit of a partisan re Signor Campagnolo, so let me respond with due tact (?). I would expect finest execution from Tullio, but sometimes, maybe once or twice a decade, the designs were not up to the execution.... And, FWIW, no one has ever claimed that innovation was the postwar lifeblood of the firm, I believe we'd have to accept.
By the way, I believe that my Schwinn Paramount 3-piece hubs (steel barrel, alloy shell) have the cups machined directly into the barrel. It's a feature, not an advantage...
