Co2 inflators /cylinders...which one??

[BigonaBianchi]

Simly donut question>>

Which co2 system are you using for standard road tyre valves? I see a couple out there .just wondered if soe were more reliable than others?
Or is it all much of a muchness?
Ta.

Much of a muchness I think; the cylinder delivers its contents in about 2 seconds flat so if you haven't got the tyre and tube sorted out right you're walking! What I mean is that I haven't seen a delivery system that can regulate the flow finely enough to give you time to check the bead is seated and the tube not trapped although my experience is limited to two types only. The benefits are speed and pressure, you can achieve 100 psi or more with no effort.

Good points....I've never used them...I would rather not carry a pump if avoidable but listening that I'm thinking out here I will still need to...its less likely go go pear shaped lol!

Cheers.

to check the bead is seated and the tube not trapped

i use this

few pumps into the tube before inserting into tyre
few more once tyre fitted to see tube not trapped
then zap to 90psi

deflate when home and refill with air [track pump] cos CO2 will leak

I swear by them, saves so much time and effort, just make sure the tube is in untwisted and your done.
I use the threaded canisters with a £5 attachment, screw the canister tight into inflator, un-screw valve on the tube, put over and un-twist and the tube inflates in seconds, job done. 1 x 16gm co2 gets you to about 100psi (use the whole canister on one tube)
You don't need to spend much more than a fiver for the inflator.
I get my CO2 from here http://www.co2cartridges.co.uk/index.php?act=viewProd&productId=256&category=303

I picked up a Zefal inflater from Decathlon for less than £10 with two cannisters. As others have said 0 to 100 in about a second. Just check tube isnt pinched before letting go.

This is one which works with a screw valve, so you can let just a little in to pre-inflate the tyre. I used it once before it fell of with my tools, and it worked fairly well that time.

As said they are all about the same, really handy for a flat in the middle of nowhere if its cold/ wet etc to save the time trying to get the tyre up to pressure.
I carry a mini pump and a weldite jetvalve

I have a Meqix machined aluminium one looks cool and works fine.

II haven't heard of this before, why does CO2 leak but not normal air?

 

[Flying Dodo]

CO2 passes through the rubber much quicker than air alone. A tyre inflated by CO2 canister will be flat within 2-3days.

I use this - http://www.wiggle.co.uk/lifeline-co2-tyre-inflator-set-with-2-cartridges/?sku=5360510046 Small and easy to stuff two cartridges and the inflator into a small saddlebag.. cheapish too as 7 spares are less the £7 http://www.wiggle.co.uk/lifeline-co2-inflator-cartridges-pack-of-7/?sku=5360510045

as said thou if flat in onroute to work its fine for trip home but as soon as home empty and track pump back up.

What a load cod. I've used CO2 on numerous occasions and the tyre deflates no quicker that using 'off the shelf' air - a 16g CO2 cartridge inflates my 23mm tyres to 100psi which is the same as I run them at when inflating with a track pump.

Yes - no need to let all that nasty CO2 out, just top up the tyre with your track pump as and when it needs it. The tyre will lose pressure a bit quicker than usual but it is no big deal. If you get one of the tiny CO2 chucks make sure you get a foam rubber sleeve for the cartridge, or wear gloves when you use it. The cylinder gets seriously painfully freezing cold in use.

Everyone else suffers. 3-6 days depending upon the quality of inner tube. You must be special in some way. Did you read the science bit in the link?
