trying to figure out what threading for a peugeot ph8 bottom bracket
Hi there ,
Ive been given what I believe to be a peugeot ph8 by my uncle . Ive narrowed the year down to somewhere between 79 and 83 .
The serial number is 0931716 PH8CE 60.
Here are two pictures of what I think is the exact same model except my one has cottered cranks .

I'm trying to source a new bottom bracket for it but I cant yet figure out what style threads it has ,British , Swiss or French ,
I'm hoping to figure it out so that I can pop in one of these cartridge cottered bottom brackets .
Sunrace cartridge bottom bracket for maintaining old bikes
I'm going for cottered as the original cottered cranks are in good shape and id like to keep them . The problem is that I cant figure out what threading the BB will have , swiss , french , or British . Anyone know which it would be or how I could find out ? If all fails my backup plan is new cranks and a threadless BB .

The easiest and surest way is to remove the left cup, and measure and/or thread guage it. That will tell you for sure whether the thread is 35x1 (French/Swiss) or 1.37x24 (BSC/ISO). If it's BSC life is easy, if it's 35x1, you have to toss a coin or do some trial and error removing the right cup to know the direction of threads.
Some brands use markings like rings turned into the face of the right cup to identify the direction of thread on French/Swiss cups. You might check a source like Sutherlands or possibly Sheldon Brown for some guidance there.

i had this same question about my psv-10. in the end, i solved it by pulling known cups off other bikes and trying them on the Peugeot. mine turned out to be swiss.
