Sounds like I may have installed them backwards. I assumed one adjusted them from the front (inside the DO) just because that's how you do it with the Campy ones. If the slotted head are to the rear, outside the DO, that leaves only a very small cross- section at the front end to stop the wheel axle. I'd think that would be more likely to cause bent adjustors than the Campy method.

> Those are actually Huret dropout adjusters, as I recall from a Motobecane Grand Touring I once owned. The dropouts on my bike seemed to be threaded. Although the adjuster threads didn't engage the dropout threads as with Campy or Simplex, they would "catch" on each other. This, along with that tight fitting plastic collar, prevented the assembly from moving around when the wheel was removed. From your comment regarding "caps screwed onto the rear- facing ends," I wonder if you may have the adjusters installed backwards. Unlike Campy adjusters, the slotted head should be accessible from the rear. Seems like a weird set-up, but I suppose there's less likelihood of an adjuster freezing tight or breaking in the dropout. Sadly, my Moto and I were victims of a car-bike accident, and the dropout adjusters were among the few salvageable parts (from the bike--the car and I survived). Sometime back, I passed those adjusters on to someone who had posted a need on the defunct CR "Wanted" list.
I also once had a Follis similar to yours with the same type of dropout adjusters and an unthreaded, unnotched derailleur hanger, suitable for Simplex and not much else. I believe the question of the rarity of these has come up before, so perhaps there's information in the archives. Or, maybe it's time for a close inspection of all-French bikes of a certain era.
