Campy record crankset question
Hi all, I came across a set of campagnolo record cranksets
on the inside of the crank is stamped "170 strada 11"
170 is for crank length, strada means road, i figured that out.
the 11 is in a box, and i'm being led to believe that it is some sort of date code.
I googled "campagnolo date code" but couldn't find any information. Does anybody know what year this particular crankset was produced in, and if there is a formula/list of date codes matched to the year of production?
