Huba huba. That's a great find.
There's only one choice, Campy from the late 80s. If I was going to really ride this thing, I say Dura Ace mechanical 10 speed, if you can still find them. Depending how many hills you have to pull and how you like to climb, I say a 39x52 with the largest 24 cog. If not, 42x52 with a 25 cog.
