Need help! Trying to sell a 1986 Bianchi Vittoria. There are some digits on the bottom side of the crank. M . 6 and 4 3 0 7 Can anyone tell me what these mean? I'm trying to figure out the size of the frame (where to measure to give accurate spec's).
I know it columbus tubing. How would I know if the parts are Campagnolo Avanti or any other? I have zero paper work on this bike as it was given to me by my Dad, so any help would be greatly appreciated.
