Presta valve unscrewey thingy...

Sorry to get technical in the title...
Yesterday morning I was going to pump up my tyres, and it being morning I wasn't at my best. Anyway, I unscrewed the screwy-inny bit from the valve and it fell out and got lost through a wormhole in my garage and is currently living life as a mushroom in another dimension.
Anyway, the tyre still seems to have air in it, so does it make a difference if I haven't got that bit at all?

as long as the little bit of metal it screws on to doesn't move you should be ok... you got a dust cap on right?Purveyor of sonic doom

It retains the seat when there's not air pressure to keep the valve seated.
As long as there's air in the tyre it will be OK (as the air pressure will keep it in place) but as soon as you get a puncture it will fall into the tube and be lost.- - - - - - - - - -

Not that it matters unless you're one of these wicker-man-burning types who actually *repairs* a punctured inner tube...0

I have buggered up a few of them with my pump.... but, hell, as long as they stay inflated and you have contingency..."Encyclopaedia is a fetish for very small bicycles"0

Tube-repairers would never burn wicker-men. Too much CO2.- - - - - - - - - -

Er, yes you can.
I think.
Or maybe you can't.
Pretty sure you can though.0 -

You might manage to reinflate it - it's a matter of where it goes if you get another puncture. I repaired a tube without the screw part a while ago, then had another puncture and managed to repair it and reinflate it a few times. But I only managed to repair one puncture. During the second post-valve puncture, it dislodged itself. The tube is now in a bin in Telegraph Hill Park.0 -

I've managed to stuggle home with such valvues before, but Ive found that trying to pump the tyres up later is temporarily succesesful, but inevitably results in the remainder of the valve being fired across the garage a couple of minutes later and killing the cat.
So I replace immediately these days.0 -

Ah, that should be fine, we don't have a cat.0
