Just curious

Kurt,

Do you remember or can someone also provide profile pics of the spoked rims of the same period airheads? I think there may be two - one with steel (formed and welded) rims and the second, being spoked with alloy rims like my R90/5 had.

I would imagine the profile of a steel rim could be determined by looking at the inside wheel when the tire is already mounted and wheel on the bike. Metal thickness would, I assume, be the same therefore profile would be the same on both sides of the metal.
