I was just fishing through my boxes and was checking out a pair of older campy cranks. I know date stamping the cranks started in '73, but when did they switch away from the 151mm BCD to a 144mm BCD? These cranks are 144mm and all that they say on the back of the crank is "170 strada." What's the story?
