replied to the thread seatpost slippage
" Every thing was right & still slipped, so I added clamp on band directly around the seat post itself .. It sits atop the frame and its band clamp.
on My Brompton It is another QR. that i took the Lip off of so it slides over the 31.8 post... to fold the bike I open both levers.
