It works the same way as most hand bicycle pumps I have, from the brass to the plastic to the aluminium of the HPX. You with draw the rod and the washer "shrinks" to allow air into the resulting vacum and when you depress the rod, the plunger expands and drives air out the connector. The only difference is the material of construction; brass and wood, all plastic, and aluminium and plastic. The only oddity is the plastic "fingers' on the HPX to have one end mate to a part of the frame. The Zefal MTN bike pump is just a fatter, shorter version of the old brass pump. |

Well, yes, but in fairness the distinguishing feature of HPX is a very functional simple method to compress the valve seal tightly by throwing the lever. The flip side of that is simple, easy release (the lack of which riders bitch about with certain other pumps). Ingeniously, the head disassembles easily with fingers, another positive design feature IMHO. Not to discount your note on Zéfal wings, the first replaceable nylon frame interface, but that wasn't all HPX brought to us. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

When I contacted Zephal four or five years ago they said they were discontinued and didn't have any old stock. |

I got replacements off of Ebay and they worked fine. But the bikes they were mounted on were sold. After I clear out my garage I should have a need for three of them and I'll contact you. |

That sliding brass head that I had on my original. It doesn't work well at all.. If you have a threadless presta valve it slips right off and if you have a threaded presta valve it tears the seal out of the pump head pretty rapidly. |
