Peugeot bottom bracket query

[iow tom]

Hi. I've picked up a Peugeot country 100 hybrid thing. The bottom bracket, even after servicing the bearings, cups and spindle, is clunking. I want to replace it for a sealed, Shimano squared tapered BB.
Trouble is, the shell width appears to be 70mm. As the bike isn't that old, I'd be surprised if it had french threads? I reckon it has bsa threads? The drive side is of course stuck at the moment with nothing to grip, so I won't know until I unscrew it which threads it actually has.
Provided it is bsa, should I go for a 68mm or 73mm BB?
If it turns out to be french, what are my options there?
Thanks

prior to gradually going ISO Peugeot used some CH

good to keep that in mind as a possibility

cycle certainly "appears" late eno' that would expect it to be all ISO

~'83-'84 was the time when the big french makers began introducing ISO, in the early time some "mixed" cycles were produced which were part metric and part ISO

Could also be that one, or both, cranks are not tight enough on the spindle. I'd check that out too. I'm sure there'll be a member with more knowledge than I, who'll be able to tell you what torsion should be used.

The bike appears 90s/00s....you would colour me suprised if it was Swiss threading. As its 70mm I though it would be Italian threading. If both cups come out anticlockwise and its 70mm its got to be Italiano.

We sold Peugeot at this time, mid 90s, although not this model.
They weren't using French on anything we sold, all 68 bsa, but the build was so basic I wouldn't be surprised if some old bbs got chucked into the box for the builders

If they were making their own bb shells, they could've used 70mm blanks to thread bsa by mistake.
If this is the case, the nds Cup will almost vanish into the shell.

Overall, you just need to get it out whichever way, then tell us the answer.
