pumping tyres challenge

rob777

Hi there,

I'm having a challenge when trying to pump up my tyres.

I have a track bike pump:

But the tyres don't seem to be getting any harder. I have the right valve in (I think) and it all feels tight... just none of the air seems to be going in the tyre.

I'm just wondering whether I need a specialist pump or am doing something wrong. My bike is a Bianchi Nirone.

Thank you for your help.

Make sure the needle in the valve on the tube isn't stuck. I always free this off first prior to fitting the pump and pumping.

Are you un-screwing the small lock nut on the top of the valve?

aha - I'm not unscrewing the lock nut on the valve so that should solve it -- thank you danowat.

Also worth just releasing the pin slightly as I finf it sometimes sticks and you are still pumping against a close valve. After unscrewing the lock nut just pish down on the pin and then release.

Erm, I hope you do this behind closed doors :shock:

Yep, always pop it first.
