What kind of pump am I supposed to use on this bike?
Old Supergo Access hardtail MTB made from Columbus Cromor, with a top peg brazed behind the seat tube. Gotta be Shrader. Top and bottom mounts look like this:

From that era, a Mt Zefal or the Silca (model name?) MTB pump probably. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

At the end of the pump head, those pumps have two sort of flat plastic pieces with a concave curve cut out to fit up against a frame tube. http://www.zefal.com/en/pumps/253-hpx-protection.html They're about 19mm wide and 3mm thick. One of those plastic bits is almost, but not quite, axial with the pump. It looks to me like it would slip perfectly into that slot. -- - Frank Krygowski |

The Mt Zefal version is shorter and fatter with the same HPX head. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Thanks a lot, boys. That Mt. Zefal "HPX Protection" piece looks like what I want. I'll see if the LBS has it.

Measure carefully because the HPX comes in 4 lengths. The non-nipple end fits over the chain stay by means of a concave bottom end to the pump. Andre Jute French dressing |

Andre Jute French dressing Correct for the eternal HPX road pumps. If I recall (always a crapshoot nowadays) the fat Mt Zefal HP only came in one length. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Too bad they ceased production. I bought several of them off of the Internet but they mostly were worn out. The French used a lot of natural rubber which rots. |
