I see two kinds of portable frame pumps to carry with me on my riding:
- Pmps that have a flexible hose that is either integral or pulled out and/or screwed on (e.g. Topeak Road Morph, or Lezyne). The nozzle is at the end of the hose.
- Pumps that have a nozzle that is right-angle to the pump tube, directly part of the pump itself.
The former are generally quite expensive, and the latter ones don't provide good leverage and are prone to bending the valve tip or coming off the valve while pumping, etc.
It seems so obvious to me that there should be a simple hose of, say 8 inches long, that would have a nozzle on one end to attach to the bike tube and the other end a fake Schrader or Presta valve head that the bike pump's nozzle would attach to.
However, I have not seen them online or in stores.
This product, if it exists, would be able to provide a lot of the convenience of those fancier pumps at a fraction of the cost, not to mention it would be a generic way to upgrade existing frame pumps. Of course, the extension should be able to handle the air pressure used for bike tires.
Can anyone tell me if they do exist and, if so, where I could get one, or what they are called?
