Hi chaingang. I agree with Greg adding that by '75 many guys were already riding / racing on 6sp. would have to look up when 12 T cogs came in, but in '75 type time the 6sp for the faster guys would have been 13x21 and 13x23. 13x26 was also prevalent, with the flatland fast boys and time trialers using corn cobs, and often a single front chainwheel. 14's were going out, but the standard bikes were as Greg described them.
