Hello all,

I am about to replace my mini pump with one that I would be able to
attach to the frame, and that would, hopefully, be more efficient.

While the old-fashioned mini pumps have a flexible hose, some of the
more recent ones do not. I have the impression that a flexible hose is
useful to avoid damaging the valve, but I wonder if this does not
degrades the performance (by which I mean, the ability to inflate a tire
to a correct pressure without excessive effort).

Do you have any advice on this matter?

Bicycly yours,

A hose adds volume, which is significant with mini pumps. With the same stroke and diameter of the piston this results in less pressure. Another problem I saw in practice is that the inner of the valve gets unscrewed while unscrewing the hose after inflating. If I would use a mini pump I would choose for a non hose one and practice on my technique but I gave up on minipumps and use CO2 cartridges now. YMMV.

I bought a mini-pump with hose, folding pump handle and folding foot piece with a dual-head snap on chuck just like a floor pump, for my sister. There is no screwing of the hose to a valve. My sister loves it.

In my world these don't fall in the category mini pumps. Depends on your reference of course.

These are 22cm to 34cm long to 9.5 inches).

Here are three examples.

I think these mini-pumps are ideal for those who have trouble using a regular mini-pump and don't want to have to rely on CO2 inflators.
