Seat Post Fabrication?

    Refurbishing a 1986 (ish) peugeot road bike and having a bit of a nightmare finding a 24mm seatpost for it. I've sourced a crowd in the US who have made their own 24mm posts for peugeot rebuilds, but it's gonna cost about 100 quid with shipping to get the post. Seems a bit much for the calibre of bike we're talking about here.

    Beginning to think that fabrication from scratch might be an option.
    Was thinking something in this line might do the job - with two half cylinder blocks holding the rails and clamped together.

    Anyway, does anyone have any experience of doing something like this? I'd give it a lash if I had the tools etc myself, but I'll probably end up looking for a metal fabricator.

    Any recommendations would be appreciated!

    Should have said in the OP - I have the old style seatpost that came with the bike, but the clamp isn't great. I was hoping to source / make a micro-adjust one. If that's what you have, I would love to take it off your hands! :D

    Cheers!

    Try LFGSS classifieds,

    and ebay.fr
    search for 'peugot tige de selle'(sp?)

    not worth getting one made, a similar frameset with standard seatpost can be found for 50euro.

    Just checked the site now; they have a 25mm post at a decent price. I guess it might be possible to get that turned down to 24mm, depending on the thickness of the walls. I'll look into it. Thanks for the heads up.

    Shim a 23.4?

    edit: I guess you'd need a 0.3mm thick shim. In my experience of cutting open tuna cans, you'd be better off using something proper...

    Had considered going the shim route, I read that other people in the same boat had shimmed up a 22.2mm BMX seatpost - but I couldn't source one. This looks like a viable option though.

    Ta,

    Edit: yeah, I was just thinking the shim would be fairly thin - brass sheeting might do the trick though
