Rethreading French frame

Hi all,

Has anyone managed to rethread a French BB shell in order to fit a modern BB?
I've been searching far and wide but haven't found a decent solution yet...

I have a Basque made frame that I want to use for a decent road setup.
Was planning on getting the new 105 group.

Cheers

No idea if french threading apply's to modern shimano parts or if you can french thread BB to run a modern chainset set up.

It's hiding under "Braze on parts and fittings "

Nice find. Great to know it's an option.
Would be cool to hear if anyone had managed it at home... at 90£ The build could add up a lot!

I heard you can make your own thread cutter using an old cup. Anyone tried that?

I have a NOS french bottom bracket if you're interested, it's just lying around here.

Hi @ilprincipe
Thanks for letting me know. What is it and how much?
The thing is, I'm really looking to use the frame for a modern groupset- which would mean hollow axle.

It's a French or Swiss brand if I remember correctly. I can check on Monday if you are interested. I was restoring an old French frame and looked quite some time for a bottom bracket. I'd let go of it for how much I paid (about £25 I think).

But rethreading is probably the better option if you want a modern group. I did the same in the end.

HI I can't remember the details right now but isn't there a threadless option you could try, I vaguely remember someone in the past discussing a similar scenario although their problem was damaged threat, Velo Orange I think was one of the suppliers but there are cheaper options, cheers hope this helps
