I'd like to ask the Francophiles a couple of additional, basic questions which relate to the original question about Juilees. My own collection of vintage bikes is limited to 70's and later, Campy-style, so I'm a bit vague on other dropouts, particularly any esoteric variations.
Are the following statements correct?
--- 60's-early 70's French rear ders had a smooth rear der hanger "bolt" which slid into an unthreaded hanger on the frame, or an unthreaded hanger plate, and a lock bolt/nut secured the der in place from the back of the hanger. ("Simplex-style".)
--- Jubilees were made with both Campy-style, and Simplex-style hanger bolts.
--- Simplex changed their hanger bolt to Campy-style in the mid- to late-70's.
I've made up the term "Simplex-style". I assume that there are a number of earlier, or maybe concurrent, iterations, which might also have been produced by Simplex, and which might have involved any number of generations of hanger styles? What names would more accurately or succinctly or clearly distinguish the 60's-70's French style, and the Italian-style which I refer to loosely as "Campy-style"?
As I scratch my head regarding this subject, I think I suddenly understand why derailleurs, pre-1975 or so, generally came with hanger plates, and frames were often built without integral der hangers.
