If I were to put a modern Shimano Crankset on my Vintage steel, mostly Campy Bike, would I be committing a vintage bike "Blasphemy"?? Had leg surgery and need to ease up a little, want to put on compact crank, have the parts, would rather have a Campy set but don't need to spend the money..I just feel funny about it, would it be better if it were Campy??
