A friend of mine just picked up a Colnago and I am not real familiar with them.
It has a full Shimano 600ex (minus the levers) non index shifting on it so that would peg the group from around 84-86 (I realize I can nail down exact dates with components.) I am assuming that the frame is from the same period, but not 100%.
If anyone could help with model, year, tubing, etc I would appreciate it.
The bike is beautiful and looks like it has been well cared for. It is a keeper for him, just trying to find some info on it.
