Classic & Vintage - 84 PGn-10. French threaded BB?

I'm looking to pick up an 84 PGN-10 that I plan to play around with a little bit. I have a crankset I'd like to use on it (OK.... I confess... a Suntour Superbe Pro track crank...), but is this BB French threaded?

My gf's 1984 PSV10 has a Swiss BB. I don't know if it's the same, but Peugeot was transitioning away from French BBs at the time.

Could be British or Swiss... Check out this page (http://cyclespeugeot.com/Threading.html) and your cups for circumferential rings.

I'm building up an '84 P18T mixte for my wife. It was made in France and has a Swiss BB. Here's a photo. I cleaned the cups and painted them "aluminum" rather than buy a $60 threadless BB. I will be replacing the original spindle.

I would leave the fixed cup in and clean the cups well. You'll need a shorter spindle. You'll need an even shorter spindle yet if you use a JIS taper spindle as I assume the Superbe Pro track crank takes an ISO spindle.

More likely British as Swiss and French threading must only have been hanging on at that time in a very few Peugeot frames with Vitus or Peugeot tubing. I beleive the 84 PGN had Reynolds 501 CrMo.

Hmmm. The plot thickens. And this is new territory for me.

Thanks Auchecrow - I have a message off to the seller with the link you provided to see if he can make the identification. Fingers crossed.

CornelJLloyd - I am almost sure you are right about the Superb Pro cranks taking an ISO spindle. That being the case, do you think these cranks will work with the short spindle. I want these to come together nice and tight. No point in having sprung for the nice track cranks if they're going to attach loose and sloppy.

That's right. The tubing is Reynolds 501. So you think the chances are this in British because it used British tubing? I'm hoping.

My '84 PSV is english threaded - might depend on when in the year they were produced and switched over.

If it were me and I just paid good money for a Superbe Pro crank, I would source the correct spindle. The cranks will work on a JIS spindle, but you can damage the crank by tightening it down hard on a JIS spindle. I assume your intended use is to use this crank for fixed riding. That puts more stress on the drivetrain and is another reason to use the correct spindle.

That said, I'm using a 70s Nuovo Record crank on a IRD BB (JIS taper) on my fixed gear and haven't had any issues. The crank isn't the best cosmetically and I only have $30 in it so I decided to forgo an expensive BB.

Does it matter whether it is Swiss or English threaded if you're going to reuse it? Are the cups not the same other than the threading?

I have a short, NOS Superbe Pro spindle. PM if you're interested.

Could be either Swiss or British but its NOT French. Dont worry about it being Swiss because in most instances a British/BSA BB will thread in.

Whaaa??? my 84 PSV is definitely Swiss threaded...that would be an oddball 84 PSV frame, if it's English. I think "big_heineken" will agree..... You sure you have an 84?

Everything that I've read about the 84 PSVs, is that they are either French or Swiss. They can be distinguished by looking at the fixed cup. If the fixed cup has a groove cut around the circumference, then it is Swiss, no groove and it's French.

Yep. Although, I'm double checking with my dad who bought it new. Essentially all original and he bought it in 1984 from his shop in Spokane WA. My 52 cm and his 60 cm both have the 1.37 X 24 tpi stamped on the bb. From what I remember the headset was English also because my brother has changed it out. Date code (at least I think it's the date code) on the Stronglight cranks shows K3.
