Wanted French threaded freewheel 6 or 7 speed Steel or alloy

[Fifthgrace]

@pigman according to the article Woz kindly posted, the doubles listed that might be suited and that were manufactured are: 12-13, 13-14. 16 is the next one on my 5 speed, so looking to minimise to 2-3 teeth max jump? if removing the current smallest cog on the 5 speed Maillard, which is a 14.

 

[pigman]

Right, I've checked my bag of cogs
There's 13/14 or 14/15.

Unfortunately I'm not prepared to combine and let you have 13/15 cos then I'm left with 14/14, which is of no use and I want to keep one combo just in case, so you can have only one

Let me know if either is of any use.

@pigman Quite understandable!: can you confirm that the 13/14 has a diameter of 42.2mm (ref Woz 's article for MC twin cogs) if I've understood it correctly to be compatible and a pic would be appreciated. I've seen some Maillard twin cogs with differing diameters of 32 & 38mm which suggests more than one body/ application? Pic of my 5 speed Maillard 700 Course for reference, Thank you.

 

[pigman]

Ok, looking at Woz's link, it seems I have the compact body and cogs, rather than the course. So, as well as screw diameter to consider, my cogs will give compact spacing which is not a problem if you have friction levers, but would be if you are indexing

I have tried to measure, but don't have calipers or gauging tools, so cannot say for definite, but a simple measuring tape suggests around 40mm. If I had to assess, I'd say, it's too small a diameter for you.

Anyway, some photos. Excuse the shabby storage loft carpet.

 

[Fifthgrace]

Thanks for that @pigman : yes looks like you have Compact body and cogs, which means they won't screw onto a Course body since the larger cog screw diameter you have is likely 38mm. Tricky beasts! The search continues...

 

[Fifthgrace]

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

Had a look thanks.

@Woz @pigman @jim haseltine Thanks for your help and the links as to how to do this. I found a bike shop in France that sells NOS cogs as singles/doubles etc. including a 13t & 14t double and doesn't charge the earth for postage (buying direct was cheaper than eBay). Drop me a line if you want a link to it. Good comms too. I now have a Maillard 700 Super Course 6spd for the NOS Gel 280/ Mavic 501 hub French threaded (32 spoke) wheel with Wolber Pro SP1 tubular tyre.

Nice one

Top turn there @Fifthgrace - I remember at one point most decent bike shops had these massive boards with all sorts of Maillard cogs to build anything custom and replace anything worn.

Odd that about 8 years ago I advertised a big bag of Maillard bodies and sprockets on Ebay and no one was interested so they went to the tip. It's really a good a thing you posted this and solved it, because in this day in age building a block is a dying art with off-shelf click to buy disposable set-ups that don't last long.

Was a satisfying 'fix' and saved c.£50 (after taking account of needing another chain whip) and hopefully with those really detailed articles to refer to, others might feel more confident in tackling too!
