I sat down with a table full of Campy parts, determined to discover some engineering reason why certain parts would be anodized while others were not. After a few hours of notetaking, a pattern suddenly jumped-out at me!
Consider the year in which each aluminum feature was introduced (notice what happens around 1958):
approx-1933 three-piece hubset with aluminum flanges - not anodized post-1951 bar-end shifters with aluminum levers - not anodized post-1951 downtube shifters with aluminum levers - not anodized 1951? front derailleur with aluminum housing - not anodized 1955? aluminum downtube shift levers - not anodized 1956 pedals with aluminum body - not anodized post-1956 aluminum seat post - not anodized 1958 all-aluminum hub shells - not anodized 1958 aluminum cranks - ANODIZED 1960 front mech with aluminum clamp - ANODIZED 1967 aluminum derailleur - ANODIZED 1968 aluminum brake levers - ANODIZED 1968 aluminum brake calipers - ANODIZED 1971 aluminum pedal cages - ANODIZED 1973 aluminum headset - ANODIZED 1974 aluminum headset - ANODIZED
Did I miss anything?
