Those dating from the late 1950's to early 1960's would have been marked "CYCLO" in block lettering at the outside edge of their relatively thin body, along with the notations "BREVETE SGDG" and "MADE IN FRANCE". In 1964, Cyclo debuted a revised freewheel commonly known as the model "64" which had a wider body and a bronze face plate that was marked "CYCLO 64" in stylized script along with "BTE SDGD - MADE IN FRANCE" which appears in block letters. Sometime in the latter half of the 1960's (...does anyone out there happen to have an exact date, please?), Cyclo introduced their Competition freewheel, which at least stateside is most commonly known for being OEM on the venerable Peugeot PX-10. Whereas other five speed models in their lineup used a traditional two-by-three threaded cogset where the two smallest cog wheels thread on clockwise from the front and the largest three thread from the backside in counter-clockwise fashion onto a "stepped" body, the Cyclo Competition model features a uniform sized body where the four largest cog wheels all thread on counter-clockwise from the backside and the smallest cog is more-or-less permanently affixed onto the freewheel body itself inasmuch as it was not intended for removal (...although this can be done if you are very careful). Another differentiation here would be the fact that the faceplate of the Competition model was rendered in a distinctive polished brass and not the bronze found on the model "64". Said faceplate on the Competition was marked "CYCLO COMPETITION" along with "MADE IN FRANCE", both notations appearing in block letter format. In 1972, Cyclo began offering yet another version of freewheel which by amazing coincidence was known as their model "72". For all intents and purposes it was much the same as their earlier model 64 with the easily discernable difference being a polished brass faceplate reading "CYCLO 72" and "MADE IN FRANCE" in block lettering. Cyclo also offered a "Pans" model of freewheel which I believe came out sometime later in the 1970's, however, I am going to have to plead ignorance with regard to its specifics as I have never owned nor worked upon one.

All of the aforementioned examples will be found having a two-notch style body as never to the best of my knowledge did Cyclo use the much improved splined interface body pioneered by their French contemporary Atom / Maillard.

If you would like to view some illustrative pictures of a couple of Cyclo freewheels that I currently have available for sale, you are invited to peruse the following links:

Can someone on the list explain the variations of the French Cyclo

freewheel? I have a Cyclo 5-speed freewheel that is only marked "Cyclo

Brevete 6005 Made in France." What approximate year would this have

been used? Most of the Cyclo freewheels I'm familiar with were marked

'competition' and came with late 60's PX-10s.
