I recently bought a 1987 Peugeot Corbier Frame which came with fork, stem, and crankset. I am pretty much set restoring this bike, although I just realized after searching the net for hours that the seatpost size (23.8mm) is abnormal and very hard to find. I've come across many posts of people with the same problem, but not any solutions that seem feasible. The best solution I found was the 24mm post custom made on yellowjersey.org, but this costs $70, and I'm really trying to keep this a budget project (paid 25 bucks for the frame).
Many people seem to say shimming a 22.2mm is the best solution, but even those posts with a rail mount on top seem tough to find, and shims that fit this also don't seem to exist. The soda can shim solution seems to be popular, but is this safe, and will it hold up to daily aggressive riding? Any other safe budget solutions are welcome.
Thanks in Advance,
