Yes, in the 80's Simplex may have made DO's to accept Campy, but as far as I am aware, the Team Champion always came with Campy DO's. And if I understand Kevin, his Simplex DO was threaded but not notched, which definitely sounds like someone modified it but didn't fully finish the job,
Simplex is the most versatile of the classic RD's as it requires neither a tapped nor notched DO, but can coexist quite happily with them, and so mounts easily on almost any road DO made after about the mid-60's. At the other extreme, the Huret Jubilee may be the least versatile, coming in at least two, and possibly three different versions, for Campy, Simplex and Huret DO's. Anyone know for sure if it was two versions or three?

I can't say when that began, but I have a an early 1980s Peugeot that came equipped with Simplex derailleurs. But when I removed the rear unit for some maintenance, I discovered the threading and alos noticed the notch in "just the right place". So I've also had Campagnolo and Shimano changers on that frame without making any modifications. It's possible that Kevin's frame uses the same bits... Fred Rednor - Arlington, Virginia (USA)
