You can but 0.1mm maulable shims now that will do the trick. I know the seat tube on my Enduro could
probably accept a 31mm seatpost now from all the wear on the walls of the tube. When sand gets in
that space it sounds like the frame is cracked. I put a camp on the post itself to prevent slippage.
Takes the load off the QR which I was breaking frequently by overtightening.
