Can someone please shed some light on Campangnolo Strada cranks and brakes I have? From what I can deciefer at the bottom of this all to familiar webpage http://www.velo-retro.com/tline.html these cranks are of a 70's vintage. Am I correct? It states:
"Starting in 1973 the crank arms have a code consisting of a diamond (1970's), circle (1980's), square (late Super Record), with a number in the center denoting the last digit of the year of manufacture (with the exception of the square:11=1985, 22=1986, 33=1987)."
Brakes? I have no idea where to begin looking to find information on them. They look identical to
The bike is pretty clearly a mid eighties model (Bertoni) with a sprinkling of Shimano 600 and some sort of Campy components. I am trying to figure out just what model/year "Campy" is on here. Any help is greatly appreciated.
