How does this work for you? A Koga Miyata ladies frame with a dropped crossbar, bought NOS for the missus. I built it up but it never did more than twice up and down the drive. It is steel, but not just any: Koga Hardlite Japanese triple butted CroMoly sweetness. Some scrapes in the paint from storage but otherwise very nice indeed. Yours for 100 GBP posted.
I should probably keep it just for the sweet rigid forks, ah well.
