You've got a good point there. My Peugeot UO8 had a steel cottered crank, and if I remember correctly the chainrings were 52-36, which is a 16 tooth difference. From the photo in this thread, it looks like the crank is some sort of Stronglight aluminum cotterless model, and the difference is much less, so maybe it'll work OK.
