What was the first year for conical nuts on Campy brakes? It seems that I had conical nuts on my 1981 Suntour Superbe brakeset but now I am looking at photos which show that in 1983 Campy was still using acorns. My San Fransico bike shop assured me in 1981 that the Superbes he sold me were almost a direct copy of the Campys, and I have a hard time believing that the Japanese could have initiated a design in the cosmetic sence, which Campy would have copied years later.
