I had Zeus 2000 hubs and brakes on my custom back in 1979. I loved the look of them. i would have had a crank set, but i was a poor college student at the time. If anyone ever comes across a dark blue imron custom with thinned prugnaut lugs, cast bottom bracket and fork crown and the mentioned Zeus part on it (midwest likely) let me know. SN may or may not be 071860 (my BD).
