Dear CR List, Following the Colnago Mexico thread 2 list members have said their respective early 1980's Colnago's have 130mm spacing....Classic content: was this done on any other makes and models,and if so why?I've always associated the 130mm spacing with the advent of 8 speed freewheels/cassettes,which I thought to be late 80's at the earliest...Yours truly,Martin Walsh in Vienna,VA
