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,
