Schwinn Paramount, Cinelli, Colgago, Grandis and I assume others, built lightweight "Woman's" frames (not mixtes).
If any of you own one, or have a significant other who does, I would appreciate knowing the seatpost diameter. This will tell me the wall thickness used in the seat tubes.
It's time to build Jane a new, lighter bike. Since building her 531 mixte in '80 I have come to the conclusion that the mixte is the superior design only when lower grade steels are used. They sure are pretty though.
