howdy folks, in the 1970s, maybe even the early 1980s, Shimano had a very nice crank with a 3-armed spider. Well, I've got rings for it ! choice of 45 or 50 teeth, NOS, $13 each shipped. I don't know if the BCD will fit any other cranks, but my approximate measurement for the BCD is 92mm, and the center-to-center bolt distance is approx. 83mm. Cheers, Mario Girasa, Cambridge, MA
