Thank you for all the responses and advice. I tried to research this subject but old school info is challenging. All my stupidness was precipitated by not being able to remove the Campy record fixed cup and refusing to buy another crankset. I read Sheldon Browns' article on fixed cup removal re bolt and nut, turning from the non drive side. Using a 24"(!) breaker bar and 2 minutes of worry it's out. Stronglight bb will be installed
