I have recently acquired a late 1950's Cinelli Serial No. 4923. It looks all original Gran Sport derailleurs and hubs, Universal brakes and steel cinelli bars and stem. The crankset has been changed to a Sugino Campy copy. I would like to change back to a period correct crankset, would a Magistroni crank be a correct change out for this Cinelli? I would be most grateful for any any advice regarding this matter and extend many thanks in advance for your reply. Ron Tandy, Westminster, California, at tmyden@aol.com.
