I also own an Italvega Superlight just like the one whose picture is posted . It is drilled out to the max. I used to have a Regina Oro chain on it which had the side pins drilled out. Just for fun, I replaced the Campy NR down-tube shifters with Huret Jubilee drilled out ones and put a black plastic rear derailleur on it. The bike is superlight and it is amazing that the manufacturer went to such lenghts to produce this bike. I have seen my share of the Japanese drilled out copies, but very rarely something like my Italvega.
