This is an interesting question as a recent Ron Cooper came to me with 27'' wheels even though I figure the bike to be 1980. I had figured 27''s were obsolete by then specially with custom builders. Are there general dates we can attach to the swing away from 27'' wheels to 700c ? I know it might be different between European and Japanese/Asian makers. With the base line and midrange bikes, when did they or did they ever switch? I left the business in 1980 and 27'' were still common but since I slumbered for the rest of the 1980s I missed the transition if there was one.
