Just received a 1982 Colnago from Italy that I won on ebay. It is a 56 cm and I thought that was center-top measurement, but it is center-center. Being a stickler for size this bike could be too large for me. If you have an Italian frame that is a 56 cm c-t and nothing less than a 39 inch wheelbase of equal value and condition that is just a tad too small for you email me off list and we will see about a possible swap.
