Will all Puegot BB's be threaded differently from standard English?

PJ

No, I have a relatively new Peugeot frame, which was manufactured in Italy and it has "standard" English BB threads.

Depends. Early ones from France had French threading. Many later ones from France had English. Current ones from the orient are English.

Great...(sarcasm here)

I found a French made Puegot at the thrift store and only want the frame to build into a fixed gear...BUT, I don't want to waste my time if it's not English or Italian thread. Maybe I'll buy it and see...the price is right.

If I do go for it...Anyone want some simplex drivetrain parts?

PJ

I could tell you to measure the BB shell width, but English, French and Swiss are all 68mm. Italian is 70mm. Maybe you could pull the right crank arm and check if there is threading marked on the fixed cup..English being 1.37x 24tpi, Italian. 36 x 24tpi.

You could get the shell tapped out to Italian threading. Or simply overhaul what you have and use the existing crankset.

DEMON

The crankset on it is a POS so I would just junk that one and replace it...if it's English.

Like I said, the price is right so I might just buy it and see what the dealio is.

PJ

Harris sells french BBs. There are also Phil Wood retaining rings which can hold either Phil Wood BB cartridge or an older Shimano MTB cartrige. I use both solutions on couple of my older Peugeot bikes - either works great. Sheldon has some very informatiove articles on the subject.

If the Peugeot is also a POS, why even bother. There are plenty of bike boom oriental frames around with fewer issues.

It's the right size (56cm), which is tough to find locally for the whopping sum of $5.

The local thrift store makes interesting pricing deals due to dirt, etc...sometimes it's $5 other times it's $30. Go figure.

Besides, this is just a toy for me to build. I'm already building a '77 ( I think) Fuji fixed gear.

PJ :-)

Do you know the model designation or production year? My PKN-10 (S/N B0xxxx, where the 0 denotes 1980) has hard-to-find Swiss threading, which can be retapped to English (same 35mm=1.375" diameter, different thread pitch, i.e., 25.4 TPI versus 24).

I don't remember the designation...I'll look when i get a chance, if it's still there.

Hints on looking for old Peugeots:
If the rear stays are half-chromed and it's at the thrift store for five bucks, buy it immediately. Look also for "Inoxyadable" sticker on the seat tube.
The switchover date from french to English threading is early eighties.
Anything lugged, brazed and built with double butted tubing is worth buying. You can also check the bottom bracket, that's where Peugeots have their serial #s. Late seventies ones have the model number after the serial number, ie. PXN10E. Anything with a "P" in the model number is probably worth dropping the cash on.

French BB threading is 35X1. Most of the upper end peugeots had nearly indestructable stronglight BBs. In the event the BB is shot, the phil rings and shimano UN72 BBS work nicely. The headset can be replaced with English bottoms sometimes, just leave the french tops. Or you can replace the fork with a newer one, and switch the headset entirely over to English.

I stopped this morning on the way to work and checked it out with a more critical eye...

The bike is a Record du Monde "Sport" and the serial #'s are on the rear dropout. they have a Y in them, not a P anywhere to be seen unfortunately. The tubing sticker is worn but it looks like it's "103" or "108"

The crank, like I said earlier, appears to be a POS 3-piece with pins, etc. There are no markings that I can see on it.

PJ

Probably carbolite 103, a Peugeot made tubing. Indicative of the lower end of the line. My UO10 is made from it.
"Record Du Monde" is somewhere on practically every Peugeot ever made. It's on all six of mine (soon to be five again. I found a wrecked UO8 at the thrift today for fifteen bucks, and bought it... because it had a pair of classic simplex retrofriction shifters on it, worth 2-3 times the 15 bucks. The frame will shortly be discarded after I finishing stripping the headset and BB cups).
Buy the bike if you want something to tinker with. It's probably an okay ride, nothing earth shattering.

I already have six bikes in the baement so I don't need another right now. BUT, I appreciate the info. If this thing is still there when I finish my fixie project (a thrift store Fuji) I might grab it for the next project. This bike has implex on it, but I have NO idea what they are, etc.

PJ

sell that Simplex stuff on ebay. You might get a small fortune for it.

Well, it appears that I have stumbled upon the correct forum for my Peugeot question.

I'm currently in the process of performing a complete frame-off overhaul of a nice Peugeot road bike and would like some information about the year built and model if possible.

The frame is designated as (Carbolite 103 Tubing) and the serial #Y4034334 is stamped into the bottom bracket on the drive side. Shifting is SACHS Huret, brakes are Weinmann center pulls, rims are Rigida with a 6-speed rear hub. This bike uses a built-in the frame seat clamp. I remember a friend of mine around 1983 who had a Peugeot that was dark marroon w/ a chrome fork and chain stays and it used this awful design of a set-screw to secure the seat post. Terrible design.

If anyone has some idea of the age and model please reply.

Thanks,

Marc

1984, French built model. Carbolite 103 indicates a lower end model, I'm unsure which one, as I get confused by the bewildering array of Peugeot models. A "b" or a "y" prior to the # indicates an eighties bike, and the first number of the serial # is the last number of the year (i.e. 4=1984).

Some info on serial numbers here:
