I know that a lot of people believe that chrome half stays positively identify a Peugeot frame as a PX10. This is a PA10. The tubing is the same as is used on the low end models. Note the Peugeot tubing decal on the down tube where the Reynolds decal would be. It can also be identified by the brazed on shift cable stops and the one-sided shifter braze on as used on the lower end models. I believe that the lugs are Bocama

Everyone knows that is a "Record Du Monde" model :-)

I believe the Bianchi Campione Del Mondo (ie 86-87 Bianchi Campione del Mondo Colorado Springs) has a similar heritage..

Nonsense!

If it has white paint and the name 'Peugeot' on it, it's definitely a PX-10 and is worth a thousand dollars.

Double that if it says 'Record du Monde,' which means the bike was actually ridden in the Tour de France (the race that Lance Armstrong won).

Also, if the fork appears bent, it was made that way, it's more 'aero' if it is bent back a little.

HTH!

What would this one with painted stays be? looks like components match what a PX10 should have, except for shifters and front derrailleur.

Yeah, all those P's are confusing but sometimes you get more than you expected. I have a 1972 PR10 which is supposed to be Reynolds butted 531 in the main triangle only. A previous owner had repainted part of it with beige housepaint so I stripped it to bare metal and discovered that everything except the fork was 531 so it's about 85% PX10. Maybe in those bike boom years demand was so high for these bikes that Peugeot used whatever material they had most of; stands to reason that the cheaper models outsold the more expensive ones so their regular hi ten and carbolite tubes may have been in short supply.

When I was 11 years old, I really really considered a near base model Peugeot that was very much like a UO8 except that it came with tubulars.
A level head prevailed and I continued saving for my first real road bike.

Peugeot's model proliferation was a great sales ploy, since the salesman could present the customer with so many choices as to wear them down, and with obviously no need to visit other shops to see even MORE choices. The customer gave up, exhausted and confused, and bought a Peugeot 92% of the time.

Peugeot, even in 1985, still had so many choices in the mid-priced range that I recently labored just to find out which model was actually the PH-501 bike that I had just bought.

Every Peugeot road bike is a PX-10....lol

It can be hard to tell at a glance a PX-10 from the U-O8, etc. but weight is the 1st thing you will notice.

Half chrome forks and chrome rear stays.
Diagonal Reynolds decal. Later models may NOT have Reynolds fork decals
Inoxydable decal. Later models may NOY have decal.
Simplex dropouts

Sometimes its easier to disqualify a bike....braze-on cable guides? Not a PX10. Fully painted fork? Not a PX10.
NO braze-ons of any kind except for the RD cable a small tab under the DT to keep the shifters from sliding down

My U-O8 is a great riding bike, very solid and durable but it does not have the lively I want run like a race horse feel that my PX-10 has.

Good thread, this can be very educational.

I've read before that some later 70's PX10's can have fully painted forks and stays.

Yes that is correct guzziee, the late 70's PX-10's did sometimes come with fully painted forks and stays.
It can be really confusing because Peugeot kind of blurred the lines between the various PX-10 models.

The chrome forks and stays MAY be the example of the classic early 70's PX-10, there are a lot of Peugeot Experts here and I for one will be watching this thread to learn even more about the unique and elusive PX-10.

This looks like a pretty good match to the black one above except for the crank. The '78 also has no chrome, but it is shown with low flange hubs. Both are in European catalogs, so I don't know if they were sold that way in the US.

Thanks for this info, [MENTION=27118]Grand Bois[/MENTION]. I will remember it.

how exactly were you able to tell what kind of steel the tubing was just by looking at the bare metal??

sure you can see if something was seemed or not. but ordinary 4130 cromo tubing looks aesthetically identical to SL or 531.

In this picture, there are spacers in the rear dropouts:


Why are they there? How about taking them out to get a little clearance for fenders?

right ... until '81 or so.

so it's easy to center your wheel when mounting. my '73 pr10 has them. i had to remove the one on the drive-side to clear the freewheel. i prefer plain screws.

Until now, I had never seen a PA10 with chrome stays. Fork, yes, but never stays. Peugeot confuses me so much.

I'm surprised a little bit of paint makes it so much heavier. But it must be true...you can feel the difference, or least some people say they can.

And, the Simplex dropouts used on higher end Peugeots and Gitanes weren't drilled for adjustment screws.

Yes indeed Jimmuller, it must be the paint, my U-O8 seems heavier than my '72 PX-10...lol

My PX-10 does not have the drilled drop outs and it is the Classic PX-10 (purchased from AZORCH here at BF a few years ago who made my child hood dream come true, as I never could afford one when I was a little kid).
I have always wondered why the PX-10 came with eyelets front and rear for fenders/racks giving its racing heritage, not that I mind and I have rode this bike with fenders /racks but mostly I just ride it clean.

Gotta love the French idiosyncrasies...

The Reynolds 531 seat stays that Peugeot used have a more rapid taper than their own stays, so they're larger in diameter at the big end. A dime centered on a 531 seat stay cap will protrude over the edges by less than a millimeter. It will hang way over on a non-531 stay. Take a dime with you when you go to look at a PX10, especially if it has been repainted. You'll avoid paying a PX10 price for a PR10. PR10's are nice bikes, but they're worth far less than PX10s.

The forks are easy. If it has a visible seam down the back, it's not Reynolds.

Now I'm confused. Is it just the white ones - or all of them?

Especially the white ones. Some Peugeots are more PX-10 than others. White ones are more PX-10 the others.

Thanks Jim - I'm good now.

The best PX-10s had steel rims, for the toughest races, and they were called PX-11s.
