Since I cannot live with only 5 cogs in back, I have converted all of my 120mm OLD bicycles to 6 speeds. (The alternative would be a triple chainring.) The Peugeot and the 1960 Capo got ultra-6 freewheels, which work well at 122mm OLD. I stretched the 1959 Capo to 126mm for a standard 6-speed freewheel.
dddd, that white PX-10 is gorgeous.
