Peugeot frame question...

Anyone got any idea when French frames moved away from using the different dimensions and thread standards?? In particular I'm talking about bottom brackets. I know they were generally 68mm same as British but the threading was different.

I've got a late 80's, early 90's 501 frame and want to swap out the old BB for a new sealed jobby. How can I can check if the threading is standard British??

A good bike shop may be able to re thread it but it will weaken the threads. You can get b.b which are just some sort of compression fitting for bike with damaged threads. That would be the easiest.

Why are the French non standard?

Because they are French and did not like the fact the i.s.o was based around a British standard probably. I don't understand why Italian frames have the same problem either. Stuburn bastards.

the one i pulled out (well wrestled out) of a 80ish pug on sunday was a BSA item and had the specs on the side ;) , slotted straight into a raleigh english BB, woot!

Being as the r.h.s of a french b.b are not l.h.t like the should be you should beable to work it out by running a screwdriver in the threads and seeing which way they go.

I have a (now infamous) 80s Touring Pug Carbolite frame - and believe me it don't get better than that.

I have got through two BBs, and both times it was quite a straightforward job. The first time, I just took the old one into my LBS and they brought out a new. The second was done by a different LBS as part of a service.

No problems on either.

sometimes it depends on where the bike was sold.
if the pug was sold in the UK in the mid-late 80's you're pretty safe. pugs sold at the same time in france would most likely have french threading though.

what he said.
in addition, if it's 80's or 90's it's even more likely to be english thread.

I'd bet hippy's pockets on it

thanks guys. i'm pretty confident it'll be uk thread and in the correct left/right thread combo. I have an old un54 lying around so will try it tentatively and see how it goes.

the pug in question above for me, had french crank arms, but it still had an english BB. so did peugout make bikes in the UK with some french parts still?! seems weird though to have a BSA BB and it looked and felt like it had been in since new. also roland, another quality carbolite frame :(

i turned down a mint pug carbolite a few months ago. i know they're heavy but there is something about them i like.

My 1984 Pug BBT mangalite frame had english threads with the original french cranks, I replaced BBT with shimano BB-UN26 and new crankset.

best decision ever. seriously carbolite must be cast iron or something, it's soooo heavy!!

my pug in it's original form has atax stem philippe bars maillard hubs (helicomatic!!!! haha!!!) and maillard pedals christophe clips and straps got stronglight cranks and chainrings and even a 26.4mm stronglight seatpost. as french as you want.

did you reuse the atax stem. weren't they prone to failing when you least expected it??

The Chrome Carlton 531 is on its way! Watch this space...

didn't know that about atax stems... for some reason the clamp bolt on the stem is stuck i can't get the bars out so it's still pretty much in the original setup. only things i swapped out were wheels, brakes and levers. i dont really ride that bike anymore actually am thinking of selling it...

carbolite's ok when the whole bike costs £15 on ebay.
