from the title i thought the subject was clothing!
since i mentioned the 'c' word, i have noticed that while i am the same size as in my late teens, clothing size designations have changed drastically.
example: in 1971 i wore size 'medium' shirts. the clothing industry now calls them
'2XL'.
somethin' wrong with this here picture...
as for bikes, if it fits i ride it. i don't worry about numbers.
