The last of the original Poili parts we have is this complete foot pump air reservoir. This is the later grey plastic unti with the Poli logo and comes complete with it's rubber shroud. These are impossible to find and a breath of fresh air for anyone with a damaged unit and needs a replacement. Don't confuse this pump unit with some of the dire Chinese copies on the market doing the rounds : this is the real deal. An ORIGINAL Poli pump.
