Hello, I am a new member to the list, but have been lurking for some time (reading the archives). I maintain and own around a half dozen bikes of the type the list reflects. I live in New York on Manhattan's snow blown west side, so riding, this week, has been out of the question. I took the opportunity to build up some older Ambrosio aero rims mated up to Campy low flange Record hubs. The true and dishing went well, for an amateur, but I see now, that these older Ambrosio rims do not have straight sides like modern aero rims. Subsequently, the brake blocks only touch at the very tops of their surfaces. Is the best course of action, now to file the brake blocks to match the angled rim surfaces? If that indeed is the case, what is the best method to proceed?
