>From pictures I'm seeing on Dale's history page and on ebay, it appears that cottared cranks (steel I presume) were still the norm on high-end bikes in the immediate post-war era. When I got into bikes as an adult in the mid-sixties the good bikes all were equipped with Campagnola or Stronglight alloy cranks. When did the change take place? Who led the way? Campy?
