I have a 1980 Ciocc Mockba that was made as a road racing frame for the Czech and Polish cycling teams for the 80 Moscow olympics. They built a bunch of extras and then when the olympic boycott occurred, the Mockba did not sell very well. Performance Bike was a newbie mail order company at that time, and I bought one of those frames for about $200. Still have it and ride the bike once a month or so. I put countless tens of thousands of miles on the bike during the 1980s and 1990s, it is a great machine. My frame got rusty when I lived on the east coast (road salt). I tried to fight the rust off for years but gave up and had it all sandblasted and painted solid green with a creme color around the headtube.
