Is “QSTSLVSPT” the gasket part that is between the seat post and the frame that quick release tightens to when clamped? Mine seems to be shredding and I need to replace it. Is it difficult to replace?
Hi Neil--This is the sleeve for a telescopic seatpost. I think what you're looking for is the QSTSLV. We recommend going to a Brompton shop to get this done, but If there isn't one nearby you can chip out the old and replace with new using special rubberized glue (CyanoAcrylate--available at a good hardware store or hobby shop). Please email us if you'd like to place an order, as we don't have this item on our webstore.
