I have been riding my Brompton for six months. My seatpost has been slipping since the beginning but now the saddle sinks about an inch every 2 miles or so. Carrying bags and everything on my body I should be close to the 120 kg limit, but it still doesn't sound right. More recently I noticed white powdery residue on the seatpost, which probably suggests some plastic collar disintegrating because of the friction. More peculiarly, when I lift the folded bike from the saddle the post slips slightly in the other direction, and when I just wheel it the saddle rotates. All this probably suggests the quick release nut was simply not tightened properly in the first place, but before I over-tighten it, is any of this common?
