Please help Identify My 1970s Road Bike Frame - French? Peugeot PX10? Any ideas?

Hi everyone Im a long term follower of this forum but this is my first post I was hoping to enlist a little help!

Ive just picked up a road bike frame that has become my latest project. Its a thing of beauty and has some excellent quality components that were what originally attracted me to it. The frame itself has no dings or cracks as far as I can see, but is pretty tired to say the least. It seems to have had a very poor paint job done at some point in its life which has taken a bit of a battering. I intend to strip it back and rebuild but what the hell is it? Ive done some research and it could be a Peugeot PX10 or at least a French bike from the early 70s. Heres the clues:

It has simplex dropouts on forks and frames.

Has a very faint BCM printed on the front of the frame near the headset. Havent worked out exactly what this means may not be BCM but something close as has been painted over.

Components are: Campi Derailers & changers with 73 patent, strongarm crank, mafac centre pulls and levers. Cineli Bars an stem.

No serial number to be seen as yet (Ill see when I get this paint off)

Reynolds 531 sticker seems to have been stuck back over the terrible paint job so may not be original!

Has cable channels along the cross bar which would make me think that it was not a PX10 although these may have been welded on later in its life.

Thats all I have at the moment any guidance from a French bike aficionado would be greatly received I'm not so much interested in what it's worth - it will be re-built whatever it is whatever the value I would just like to know what Im working with.
Thanks in advance - Martin

Can't believe no one spoke up so I'll give you a bump. The hanger on the Nervex dropout looks to have been dremeled with at somepoint.



I think BCM is for the lug maker. Strongarm or Stronglight? Any idea on threading on the BB or the steerer?

Looks French to me. Could be a PX with those dropouts.

Figure out the BB threading, find out the seatpost diameter, and measure the OD of the main tubes. That will confirm that it's French. Any serial numbers or anything you can find?

Drilling and tapping the Simplex dropout is common so that a normal rear derailer can be used. It looks like yours was ground down (as BG points out) to hold the b-tension screw of an RD.

messyprofessor- Perhaps an early 1970s Gitane Tour de France? The dropouts, stay ends and seatstay caps all say yes. The braze-on brake support was probably removed when the re-paint took place. Look here for details of the TdF. Don't worry about the dremeled hanger - a restoration Simplex Criterium derailleur will just bolt right on again.

The bicycle is not a Peugeot. The half wrap seat stays suggest Gitane and the chrome plated forged drops indicated a Professional Model. Here are some pictures for you to compare your frame set to...

Thank you all for your swift responses and really helpful comments. I hope to strip it back over the weekend to see if I can unearth any serial numbers or further identifying details. I also need to borrow some callipers to get some measurements.

Bianchigirl - you're correct the crank is stronglight.
FastJake - The rear dropout has definately been ground down to fit the campi RD (and not very well).
bertinjim & randyjawa - The Gitane frame looks very very similar. The lugs, dropouts and geometry look almost identical. The only thing that throws me off is the cable channels for Fd & RD mounted on the bottom bracket. COuld these have been a later add on???

The Reynolds sticker is in English- this makes me think it was a later addition borrowed from elsewhere.

I'll get back to you all over the weekend when I've put a bit of time into the frame and (hopefully) have something more to go on.

Thanks again, Martin

I'm with it being a Gitane most likely late 60's early 70's the seat cluster with smooth almost wrap ends looks Gitane. It looks and is likely higher end French. There is a common reaction to try and identifie all better made French stuff as PX-10 which sucks during this era there where a lot of other great French bikes made that are as good or better than the PX.
