Yes... I have a PLX8 named Edith and as she is a 50's classic I named her after another classic (Piaf).

Anyways...

I have noticed that a few of the bikes shown appear to have Ava stems which are also known as death stems for their tendency to break spontaneously... the Ava stem on my UO8 was fractured halfway down it's length and am sure it came this way and was not caused when I removed it.

These stems and old bars need to be replaced for safety reasons.

So when you go to replace that death stem you will need to find a stem that fits and here is one of those quirks... Peugeot used a 22mm quill stem and a standard quill is 22.2 so one will need to break out the sandpaper to make a modern quill stem fit. On the bright side, you will be able to fit modern alloy bars after this is done.

The steerer threads are 25mm, and not 25.4 (standard), the bottom bracket has 35 mm by 1mm metric threading and is right hand thread on both sides... a standard bottom bracket is 24 tpi. Like Italian bottom brackets, this can cause the fixed cup to unscrew itself so it needs to be tightly secured and at times, a little blue Loctite goes a long ways.

You may also run into a Swiss threaded bottom bracket which is also metric thread but has a conventional reverse thread on the fixed cup. French cotter pins are 9mm, and the handlebar clamp is also be smaller to accommodate narrower steel bars.

Velo Orange now offers a French threaded cartridge botttom bracket... this will save a person a great deal of grief in trying to find a Sugino #5 spindle which will replace the cottered one if you go that route. I have a few French spindles and spare bottom brackets for whenever I need spares but VO did a great thing in making these bottom brackets.

Now I want them to make one to fit a Raleigh bb shell but that is another story.

One should not have to worry about French threaded pedals on UO8 models and most imports had standard pedal treads and standard freewheel threads... but there are always exceptions.
