Have just purchased an old 25? year old Bianchi - with Campy Gran Sport on it. I remember some time back someone mentioned that you can date the equipment by the stamp on the cranks. Can't remember what the circle and the triangle indicated. Mine has a circle with a 2 inside it. What is the year of manufacture. Thanks
