Here's why I ask: in my experience, a typical Italian frame from the 1960s and early '70s had no extra space between the outside rear sprocket and the chain stay. In fact, if you tried to use a Suntour freewheel - which is slightly wider than a Regina - the chain wpuld rub the seatstay as you shifted to the next smallest sprocket. So if you were to mount a Porta Catena piece, where did you find the extra space? Fred Rednor - Arlington, Virginia (USA)
