I bought a beautiful PMP titanium seatpost . I already had a classic 27,2 version but I sold it times ago . Now I needed a 31,6 size and I found one here in Italy . Unfortunately when it comes I discover it was the wrong size : 29,4 instead of 31,6 . The guy who sold it was not very polite , so I now need to find a solution . I should use a shim but it's hard to find the correct size , so if anyone can be interested comes on . I will post few pictures soon : it has no cracks or signs . It's 350 mm length and I will sell at the same 75 € I bought .
