Listen in, listen Ian!
I was planning to go out on my bike, for the first time in ages, but I haven't because I couldn't work out how the hell to pump the tyres up. The last time I needed to pump tyres up, you pulled the flexible tubey bit out of the pump, attached one end to the tyre and the other end to the pump, and did it. Now it seems to have gone all hi-tech in an apparent attempt to fix something that wasn't broken.

This is the fitting on the wheel:



This is the business end of the pump:



which dismantles thus:



and:



New fangled bike experts, help me out here!

Don't you just unscrew the end of the fitting on the wheel until it's moved past the screwy bit to leave a hole, then stick the orange screwy bit on the pump into said hole?

I haven't pumped up a tyre in about 5 years so if this causes you house to explode don't sue me.

That's what I thought, but the end of the wheel fitting doesn't unscrew and come off the bike - the brass bit unscrews and reveals a stalky bit which has to be pushed in to release the valve. And the orange bit has four holes in it, rather than one in the middle.

I think the mustard coloured bit can be inserted either forwards or backwards? your pump is the same as mine... but it's been a while. i remember taking ages to figure it out at the time as well...

You have a Presta valve and a Schraeder pump. So they won't work together.

Some pumps are smart, and let you invert the little rubber thingy inside the business end that changes them from Presta to Schraeder. You might need to do the same for the yellow plastic bit.

Also: there are little brass widgets that convert a Presta valve to a Schraeder.

Oh, cool. I'm not just being useless then. Thanks.

I had a look, and there do seem to be invertable bits in the pump but even then, they don't form any kind of seal over the valve.

If I go out and get either a Presta pump or a converter widget is there any other information I need to take, like the size of my valve (missus) or are they a standard size?

Put the yellow bit in with the inny-bit showing and the smaller black bit on top with the wider opening downside, then the screwy big black bit should go over the top of them all and secure them in place to receive the valve. Or something.

You might have a schraeder/presta thing going on, but most new bike pumps are ambivalvey.

You might still need to unscrew the brass bit on the valve to let air in. And then rescrew it afterwards, obviously.

Well, for one thing, you're spelling tire wrong1 I think that's your first problem right there. I mean, look! Tyre is so ugly.

Looks a lot like the brass coloured bit on the end of your fitting is the remains of an old pump end...
