Ive just brought an old Peugeot Road Bike and as far as I can tell it is a Peugeot Competition, but I wondered if you guys knew anything more about Peugeot Competitions.
they experts will want the following...
pictures of frame, stickers, bottom bracket, head tube and of serial numbers (seat post or BB)
lots and lots of pictures...
Heres some pics of the bike.
Im not exactly an expert but I would guess that that is a 1981 PKN10. On the bottom bracket or on one of the chainstays there might be a serial number that might be of help. Nice bike!
P.S. The rear derailleur probably wasn't the original derailleur.
