I know this post has been inactive for awhile now, but I've got an old Peugeot that I can't find an adequate seatpost for. I carefully measured (and re-measured) the frame, and it requires a 24.4mm seatpost, which I can't find anywhere. The previous owner decided to put in a 24.0mm seatpost and call it good, but I'm having trouble getting it to stick. Does anyone a) know where I can find a 24.4mm seatpost and/or b) want to trade for the 24.0mm that sounds like it's in a bit of demand? Let me know if you have any advice.
