Wanted French threaded freewheel 6 or 7 speed Steel or alloy

[Fifthgrace]

Looking for a French threaded freewheel 6 or 7 speed in good or NOS condition. Willing to purchase, but would also consider a swap for any of the following: 14-22 Maillard 700 Super Course French threaded (5v), and Italian threaded Regina GS Corse SICC (6v) speed 14-22, Regina Extra ORO 13-23 (6v).

Can't you use your maillard french threaded 5 speed and swap just the small cog for a combined double to give you 6?

Never taken a freewheel apart, and are doubles easy to find? Do the cogs need to be French threaded?

The cog threads are universal across all BSA, French and Italian freewheel bodies.
If I recall correctly, the cogs with plastic spacers are splined in place (three splines) and have two different internal diameters with the rear most pair being a wider diameter than the others. The top sprocket on a 5 speed and the twin setup for 6 speed screw on to the body and so retain the other sprockets. I believe that the splined cogs are interchangable with some of those on other Maillard 700 models, the threaded sprockets less so.

Thanks for the info. Given the uncertainties involved, I think it's expedient to search for a ready-made 6 or 7 speed French threaded freewheel, but appreciate the option.

I've got a big bag of maillard block spares and can have a look if you want to try the double cog. (no promises of availability though). What sizes would you want your smallest cog to be?

There's always Hilary Stone, usually has the odd French 6 speed in

Thanks @pigman If you have a 12-14, or an 11-13 double that would be ideal to give it a go.

Thanks @Woz : It made a lot of sense though I think the final instruction was a little concerning!:

• And crack, the sprocket ends up giving way and unscrewing... Otherwise, the thread is in reverse!
