hmmm. my '80 pkn10 has screws through the drops. my '73 pr10 has the other, bracket kind of adjustment fittings. both were 531 main triangle bikes. but i wouldn't consider one frame better than the other.

except ... by '80, the simplex hanger was threaded, sized and ready for a campy nr derailleur.

I don't think it really matters whether it is a PX10 or not. PX10's weren't that great anyway - clear signs of being mass produced and often poorly executed. Your PA10 is great looking and no doubt will ride really well. Just enjoy it.

Whose PA10 are you talking about? Mine is great looking and rides really well, but I haven't posted a picture....until now.

My PX10 is greater looking and is a better ride, though.

[QUOTE=zazenzach;17056202]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.[/QUOT

531 tubing is stamped as such

Eddy Merckx and Bernard Thevenet both rode white PX-10's in the TDF in the 70's.
I know the stories about they were re-badged xyz bikes, but does it really matter?
They probably could have rode any bike and still won...

sced, they may have been factory made, but it seems Peugeot got it right with this model.
I have rode a lot of vintage steel and nothing quite rides like the PX-10, for me anyway.

I guess I like the idyllic notion of the PX-10 in that the only REAL PX-10 was the white one during the '70's...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."

What is the weight difference?

Oh, maybe 4 or 5 pounds. More if you measure it in kilograms.

It really depends on whose scale or marketing material you believe. My UO-8 always weighed in (the few times I bothered to weigh it) at over 28lbs. IIRC the catalogs said 27lbs. I have no idea or memory of what a PX-10 was supposed to weigh, so I'm guessing.

The claimed weight of my '74 PX10LE was 21 pounds, but they probably based that on the smallest frame size.

By the way, the weight is not the first thing that I notice. There are plenty of visual cues, some of which I've tried to share. Besides, I'm not in the habit of lifting bikes that don't belong to me. ;)

Components may have been changed, but you'll rarely see a lower end Peugeot with top tube cable clips. I can't say never because someone cut off the cable stops and added clips and posted a picture on this site a while back. It was an orange UO-8.

Jim, you are bad!!

:D Apparently a bad typist. Or at least a bad preafrooder.

My UO-8 is white from the early 70's so it is at least partially a PX-10.

The PX-11s you speak of were limited edition Spinal Tap PX-10s. You could also order the optional extra-large seat for big bottoms.

With mud flaps?

I'm laughing so hard I don't remember.
