Oh, there's no doubt that they would work. It's the acceptance of marring of the finish on the parts IF they were to be re-used that I found surprising. But then again on old clunkers that are in sad shape when they come in anyway a couple of bite marks on the lock rings is hardly a big deal I guess. Fair enough. As long as we agree that this would not be acceptable on some nice old vintage Campi cup and cone BB then my ruffled feathers are smoothed...
