I just purchased a 1999 Bianchi Volpe off eBay. I'm waiting for it to ship. I have a 105 groupset that I'm going to put on it, and I am wondering whether the bottom bracket shell is Italian or English threaded. If I had to guess, I would say it is probably Italian threaded, but I'm not sure. I recently got a 2004 Bianchi EV3, and it's BB shell is English threaded (I had an Italian threaded BB waiting for it). I believe only Bianchi's Reparto Corse frames got this change to English threads in the last few years, but I'm not sure.
Just want to figure this out so I can get an Italian threaded 105 BB for my Volpe if necessary (I have an English BB this time).
