I have recently bought a Specialized women's road bike and for the last couple of weeks was borrowing my boyfriend's hand pump with no real issues.
Last night I finally purchased my own (Topeak RaceRocket HP) but each time I try to inflate the tyre (just a top up of air, not from flat) I can either hear air hissing out (I believe the pump isn't screwed on enough then) but even a quarter of a turn too far means the pump won't work as the air pressure seems to be too much and this would suggest I've screwed it on too tight. Just can't seem to get a happy medium.
It could be resolved with a floor pump but as I've just dropped £30 on this, I want to be sure before I spend another load of cash just to eliminate possibility.
Any suggestions? Should I return the pump or am I doing something wrong?
Thanks :) x
