The Brompton seat sleeve sits inside the frame allows the seatpost to slide up and down smoothly

This is a replacement seat post sleeve with locating key

If your seat post starts to slip - rather than keep tightening the seat post release bolt (which can ultimately result in frame damage if over-tightened) it may be that the seat post sleeve needs replacing

It will wear over time due to the friction of the seat post going up and down - originally it needed to be replaced by a Brompton dealer as a reaming tool should be used to remove the old seat post sleeve

  • B75 / A Line
