Anyone had a dumbass experience with the Topeak Race Rocket or similar rubber tube type mini pumps...? I occasionally seem to make an error screwing the head onto my valve so that when I remove it having inflated the tyre I end up unscrewing the threaded head of the tyre's valve itself - immediately releasing the air i the tyre. I'm clearly being a dunce as I can find no online reference to this happening to anyone else. What am I doing wrong people? I feel like a right tit!
NB this doesn't happen every time. I am often able to inflate and then release with relative ease.
