These are the more extreme, earlier version, I believe. They're obviously way out of round, just looking at them. I'll try them out, probably do the 'one arm over' thing. But I also have a set of 7410 Dura Ace rings could use if I can't stand them.
Oh! And I went back and looked carefully at the
1989 Schwinn Lightweight Bikes catalog online, and I found that even the 23" came with a 40 mm Cinelli Giro d'Italia bar. The 23 had a 110mm stem, vs the 22's 90. I suspect, once I get this 22" one all built up, all the 23" Circuits out there will crawl out of the woodwork, too late for me to buy them.
