Sorry to go AWOL after posting, busy day. Also, I appreciate everyone's input so far.
It's a 1980 Masi Gran Crit, serial number and shop owner both reveal it was built in Cali, so technically it's not an Italian bike, but it's a gorgeous frame and I would love to do it justice in both cosmetics and functionality. It's definitely a little beat, but the geo is perfect for me, and I'm in love. I don't know where to get old Campy parts except for ebay and even then, I wouldn't know what good condition or price would be, which is why I inquired here. In a perfect world, it would have Barcons or Ergo's, but that can wait.
I was hoping I might be able to get suggestions on where and what t
o buy. For now, I'm on somewhat of a budget until I can unload some bike parts, perhaps including this 105 group. I also have the rest of the 600EX group, which is Campy-eqsue
Should I register and dig through the for sale thread?
