Yes and yes.

My advice would be to not to screw the trigger onto the canister until you need to use it so there is no risk of the gas leaking over "x" weeks or months (don't ask how I know this). And carry 2 canisters so if when you need to use one for the first time if you do not get in on correctly and some of the gas escapes you've got another one handy (don't ask how I know this either!!)

You can get two road tyres out of one canister.... but only at the same time. The gas leaks pretty quickly once punctured. You can easily get well over 100 psi in one tyre.

Two road tyres out of one 16g canister? Erm, really?

In my experience a 16g CO2 will do a 23 x 700c road tyre to between 80-100psi depending on how good you are at catching the leakage. No way would they do 2 x road tyres to anywhere near a decent pressure

Obviously not a talented inflator...

Watched my father in law do one the other day, was hilarious to watch as it was the first time any of us had used one
It leaked a lot and it seemed to freeze around the valve, the tyre inflated enough though

Look at this in my local lbs today, this I need to invest!

Remember to deflate the tyres once home and re-inflate them with air

Really? Why's that then?

[47p2]

A tyre inflated with CO2 looses pressure quicker because CO2 is very soluble in butyl rubber so inner tubes seep the co2. You need to re-inflate when you get home with air from a pump.

Didn't know that. Of course you could always wait until it goes down a bit and then top it up.

It doesn't get easier, the bills just get bigger

[Simond S]

As the parts get lighter, the bill gets heavier

I thought I would try out my co2 canister on an inner tube this morning. Manage to blow the inner tub up. Note to self, only inflate inner tubes when inside th tyre.

Worked very well. Came from wiggle and was one if the cheaper ones.

Have a look at Lezyne CO2 inflaters - they claim to be trigger operated and therefore precisely controllable. Lezyne kit is also very bling in the looks dept, and of very high quality

Not convinced by CO2; a decent pump will get to the same pressure, never runs out and has no ongoing costs. Sure it's slightly less bling, but far more practical.

Is there really a pump that'll put 120psi in the tyre and fit in a jersey pocket? I haven't found one.. until then co2 will have to do..

There're some that claim, but it takes a herculean effort (not to mention bloody ages) to get anywhere near it.

I've taken a totally flat spare and put a 16oz Co2 into it, gave me a reading of 110PSI on my track pump when i got home 12-15 miles later, no way would a say it will do two tyres except as a ride gently get you home measure.
I carry two 16oz's and some ready glued patches, that lot weighs less than a pump and is good for two flats and a low pressure get you home 3rd if you are seriously unlucky.
I've had 1 puncture in 1000 miles and may well regret the above...
