I got this bike from a neighbor for free. He told me his brother had the frame custom made and had it built up. He guessed that it was from the early 80's but that it could be older. The frame is columbus steel. It needs a lot of work, but I want to make sure it's worth it to spend the time and money to do it. It has 12 speeds, all Campy Record, and Mavic tubular rims. It also has leather bar wrap and a leather seat. So, I'd like to know if you guys know anything about this bike.
