Interesting! I never actually measured donor frame BB shell - just assumed it was 68. I guess "Lug - 70" means bb shell lug - learn something new everyday! Frame is Columbus Cromor, it is 1988 Miele Gara. I am borrowing crankset (have another exact same in the mail coming) to put it on Miyata Terra Runner which has 68mm shell (this one I measured just to be sure).
