"I just love standards, because there are so many to choose from."
It would have been nice if 630mm rims had never been invented, just as it would have been nice if the U.S. had followed Ben Franklin's recommendation to make the American Revolution complete by adopting the French metric system and overthrowing Imperial weights and measures.
I remember the early 1970s, when 700C/622mm was the hard tire size to find.
