I'm looking for a Regina Corsa 5 spd freewheel to replace the trashed one on my 1974 Gitane Tour de France. I had a bit of a crash, breaking spokes in the rear wheel and had to have the old freewheel hacked off at my LBS. The threads on the hub are still good, so now I need to locate a suitable freewheel. The original was a Regina - I think a Corsa. I know some threads on the bike are "French" - like the pedals. Are there also different threads for the freewheel? Here's a pic of the original

The threads on your hub may indeed be French. Which hubs are they? Normandy? Campagnolo Tipo? Kind of unusual that a Regina would be original equipment. Most, as I remember, were Atom. Mine was, anyhow. New Regina Corsa freewheels, especially with those larger cogs, are not too easy to find and expensive when you do find them. Did they have to completely destroy the freewheel to remove it? Any of it salvageable? Bob at Freewheel Spa may have something that will work for you, and is a swell guy. A member here too.

I doubt that the Regina was the the original freewheel. I'll bet you'd like the way it shifts with a modern twist-tooth freewheel.

Do they make' em with French threading, GB?

Something tells me probably not. I beleive I have one spare French threaded freewheel kicking around here someplace. IIRC, it's either an Atom or a Maillard.

Too bad they trashed the Regina taking it off.

Take a look at the photo - you can see the "CORS" - as in CORSA - thru the cutout and that the hubs are Campagnola.

Are there any markings on the freewheel body? These can indicate the thread type:

The hubs themselves may also be marked for thread type:

I had a Gitane TDF with French threaded Tipo hubs and Regina freewheel. Still have the freewheel, its like new, EXCEPT, bike shop tore up the removal slots when removing it for me. So if you want a freewheel that probably won't come off in the future, I have one.

Maybe Pastor Bob could make one working freewheel out of two dubious donors?

I've actually had pretty good success at transplanting Regina inner bodies to address the issue of botched up removal notches.

The other interesting thing I've discovered is that Atom inner bodies work inside most Regina 5 speed bodies. Even the Regina bearing race/retaining ting fits on the Atom inner body, so it takes a keen eye to know the difference. The beauty of this transplant is all the Atoms I've come across use the old Regina splined removal tool as opposed the the 2 notch tool which has a way of ruining the freewheel.

So for instance, if the inner body on this Corsa I worked on had mangled notches---



...an option would be to replace it with an inner body from this type of Atom.

So--- think before you chuck the Atom in the trash. It does have a redeeming value.
