Peugeot Touring Seat Post Dilemma

  • I've been working on my first fixed conversion, using a Peugeot Touring frame from the 70s/80s.

    It is up and running, but I want to put in a new seatpost. Unfortunately Peugeot seemed to use their own irregular sizing - I had my LBS put callipers on it, and it looks like the diameter I need is around 24.8mm...

    Has anyone else come across this? Any ideas where I could find that sized seatpost?

  • I converted an 80s peugeot frame and I threw the seatpost away!!! I then read a forum post somewhere saying that it was impossible to get hold of 24.8mm posts. I ran to the bin and found it. I was very lucky.

    There was a guy at Brick Lane Bikes recently who had his Peugeot resprayed and stripped and had all the brazings taken off. He spent a lot of money on it £600+ When he came to pick it up he realised that the post he had wasn't the original and so he had no seat post. We tried to get one in but they just don't exist. I recommend Brick Lane Market..... there are tons of old seatposts on the stalls, of about the same age as your bike. I'm sure you'll find one there.

    The peugeot seat post is a real pain! And it's so f**cking thin.... it looks silly. I know, cause I have to look at it every day!

  • Can you squeeze in a lightly-sanded &/or well-greased 25mm post?
    I know they are made for use with shims, butat least this is another option if you cant find a chep one..

    USE are about £60ish - obviously 2nd hand on Ebay is cheaper

    EDIT

    Ignore what I said!

  • Get a 25 mm seat post, don't get a expesive one get a cheap one with plenty of meat, take it to a machine shop and how ever much you want to bein the frame get them to turn 0.2 mm off of the post. Give it a test ride off. It should not be much of a job it would be a 5 min job with a lathe.

  • Alternativly speak to a frame builder and see if it is possible to ream out the 0.2 mm from the top 6 inches of the seat tube. THat would pro be the best solution. Give a frame builder a ring.

  • Thanks...

    Someone else has recommended 'Recycling' on Elephant Road - apparently they have quite a few second hand bits and bobs lying around.

    Sounds like there are a few possibilities though.

  • or buy an old peugeot !

  • Where are you Roland? I have a couple of odd sized posts at work, theyre short but deffo odd sized!

  • for some reason i keep seeing some old peugeots abandonded. i think there is at least one near waterloo station. if you know that they've been there a long while, see if they still have the seatpost. might save you from buying a new one and it'll be recyling old parts. if i see anything, i'll let you know.

  • Cheers SE Andy!

    I am based in East Dulwich, work near Victoria... Can get anywhere...

  • Roland, drop me an email with ur contact details (work address etc) and I`ll get them biked up to u 2moro.

  • Sorry to hijack, but I have the same problem.

    I have a 24mm seatpost. Does anyone know how much shim (i.e. 2 layers of Stella can) will be required to fit into a frame the same as Jonaent's (above)?

  • i'm not too sure with using stella cans as a seatpost shim. it's fine for stem/handlebar bits but the seatpost is under so much stress you're better off finding a bigger seatpost and sanding it down. i tried that myself and the can was totally grinded into powder with the seatpost constantly slipping.

  • Same problem for me. Pity because it's a lovely old peugot. Even more of a pity because when I took out the old bottom bracket I found out it was a damned french thread. Why do Peugot have to make everything difficult? My mate has ended up with all my Campagnolo goodies as a result...

    Anyone know where I can get a french thread bottom bracket for an early 70's Peugot?

    If you have any luck on the Seatpost Ro-Land, let me know. I'm up in Tulse hill...

  • he might have resolved this in the year since he started the thread.

  • He got a 25mm post from my good self and sanded it down, I believe.

  • are you sure he didn't use an inveerse shim?

  • I'm not certain.
    Had they been invented when the thread was started?

  • we tell people to use the search function, but we whinge when then do..

  • whatever.

    Just gab yourself a threadless bottom bracket, I've been using one on my Pug and it seems fine, hasn't come loose in a few months now. I'm using one of those Decathalon seatposts too with no problems.

  • I'm looking for a 24mm seat post myself.. Anyone had any luck getting one?

  • ^ wot JDB sed.

    Use the 23.4 decathalon post and the 25mm shim that comes with and simply chop it in half length-ways (so it goes 180deg round the post) and muscle the post in.

  • Thanks broker..

  • I can confirm that the Decathlon thing works quite nicely. Well, it worked for me at least ;)
