French Bottom Bracket question

if Poguemahone is around, maybe you can answer this. or anyone else...

i have a mid 70s jeunet (i'm pretty sure) that i have been riding as a single speed and, recently, fixed. the chainline is passable with the acs freewheel, but worse with the dura ace cog. part of it is the hub and i'm saving my pennies to build a new rear wheel, but i definitely want to do something about the spindle.

the bottom bracket is a nice french TA that's in great shape. it has a 117.5 spindle on it right now. my question is, do i have to buy the $50 TA-brand 111 spindle? or can i put any spindle in this BB? i'm running bulletproof cranks right now and plan to upgrade them sometime next year, so it would be nice to use a normal, $10-$20 107-ish mm spindle.

doing some research, i saw something like a "3-series" spindle fits french BBs... anyone know?

Mixing brands of spindles and cups is always iffy. If it works, fine. If you want to be sure without trial and error, buy the TA.

I have run several spindles in the original TA bottom bracket of a PR10, all work fine, providing you match the shell correctly. As Sluggo says "trial and error" - last week gave up and fitted a YST "Threadless" BB which has worked out well.

A Specialised 7NL suited the original cranks on both a re-dished and track hub fixed wheel, chainwheel outside & inside respectively.

Go for it.
