Retapping BB's
 

Customer has a French threaded Peugeot, he is attached to.. wanted a new BB , 68-103..
Of course Italian or Brit standards remain, French thread, has become yesterday's news..

Any of You had success rethreading French 35mm BB
into the South of the Alps
Italian 36 ?
thinking Thread reversal and how much closer Brit (as if 34.8mm)
to 35mm French is, Italian is the way to go..

Feedback?

Grazi..

I have never done it, but if you get it to Italian, you can buy sleeves to make it standard threading.

You can still get French BB for square taper

Bicycle Research made a reamer/Italian tap set for just this purpose:

They're hard to source these days, but perhaps a local shop may have a set?

Otherwise, French thread BB cartridges are available from Velo-Orange.

sold out of 103 next size up 107 seems like a better option than retapping..... buy 2 if the guy is keeping the bike for a really long time :)

Phil makes French retaining rings (not really cups buy...) and various BB spindle lengths/tapers. No frame mods and completely reversible. But we don't know if there are other reasons to mod the BB threading. Andy

Yea, I've been aware of Phil option for over 30 years...
