Simplex most definitely made them to fit Campy brazeon posts. I probably have at least half a dozen of these installed on various bikes, although I must admit that most of them are the newer cutout style.
I've also converted these to clampon using clamps from cheap Simplex Prestige shifters. This means the Prestige clamp posts must be the same OD as a Campy brazeon post.
Can't remember for sure if I ever converted clampon Retrofrictions to brazeon. The newer style is probably earier to find as brazeon, so one is usually trying to convert brazeon to clampon rather than the other way around.
Since Steve says his clampons have a smaller ID than Campy, that must mean that the Retrofriction clamps were different from the Prestige clamps. Isn't French stuff great?
