Someone stopped for me today and kindly pumped up my tyre with a CO2 pump.
It was easy ... fantastic, in fact. So, I'm looking at buying one. I want
one I can use on both my MTB and my road bike. So, do I need 12g and 16g
threaded bottles?

Thanks to all those that stopped in Richmond Park today to offer help.

My brother used to have one of these, it was more hassle than it was worth.
Half the time it would fire off before you were ready to pump and wasted
itself, the other half of the time it functioned but didnt have enough to
get an MTB tyre full. Plus the cartridges were expensive. Plus releasing CO2
into the air just to save your (general, not yours specifically!) wimpy arm
pumping is a bit pathetic.

Hope the designs have improved these days, and prices come down for refils.

I tried one once and it blew the tyre off because it inflated so rapidly and
the tyre wasn't on properly. The second time I was with a group and someone
had a puncture and everyone was very impressed with how well it worked.

I don't use them though now because they're heavy to carry, expensive to use
and you only get one go at it whereas with a pump you can keep pumping up a
slow puncture until you get home.

I carry one whenever I am commuting, or cycling long distance. I also
carry a minipump as well, although Innovations make a combined
CO2/minipump.

The one I have uses 16g threadless cartridges, with a screw on plastic
cover. I have used mine without a problem about 5 times.

According to the cartridge packet, one 16g cartridge will fill a 26" MTB
tyre to 40psi/2.7 bar, and a 27" 700C road tyre to 130psi/9 bar
So a 12g cartridge will fill a 27" type to 98psi/6.75 bar
Obviously a fat road tyre will inflate to a lower pressure than a thin
one. So it really depend upon your tyre sizes.

They are a completely stupid idea.

Get a good pump instead.

Innovations Air Chuck works really well.

My "good idea" pump yesterday didn't work at all, and I don't have any built
in places to put my pump on. I do have one of those high pressure pumps, but
it's too big to carry without fitting to my frame. A CO2 pump would be more
ideal, I was also most impressed with this one.

Isnt that more down to having a poor "good idea" pump? I have a dual-action
switchable "normal" pump that works all types of valve and up to 80psi -
sure its not going to get you back up to max running pressure but its most
of the way there and fully usable. Plus its not much bigger than a CO2
pump. Oh, and when you get multiple punctures (happens more often than not
in my experience) you arent screwed and dont have to carry a breweries
worth of small CO2 canisters!

Mine came with a bracket - which didn't fit the frame properly and when I
tested it I couldn't get the pressure much past about 20psi which would have
damaged the tyres if I rode on them.
A £1.99 pair of plastic pegs has allowed me to attach my trusty old Halfords
pump to my frame. I have a schrader-presta adapter (front uses presta, rear
uses schrader - bike shop's fault) but often carry a presta tube thingy
anyway.

More of a "good pump turns bad" situation.

My "good idea" is to carry a mini pump *and* a CO2 inflator. The
combination is smaller and lighter than an HPX pump. Not only do you get
back up to full running pressure (after the first p*ncture), you do so with
great speed and ease.

Multiple p*nctures happen less often than not, IME, but having the pump as
well means they can be dealt with when run out of CO2.

Lighter alternative to a HPX is the Topeak Master Blaster. Seems to pump
just as well (I have one of each) at a considerable weight advantage. Both
massively better than minipumps (I have a Blackburn Airstick, which will
pump things up, but is quite hard work).

I do that. I normally carry two cylinders, and when I remember I am
going to leave one at work. Earlier this year I ran out of cylinders
when I could not find the box they were in. I then ordered some more,
put two in my saddle bag and when I put the new spare ones away, guess
what I found?

I have only had two punctures in a single day once in the last three
years. The second puncture was as a result of pinching the first new
inner tube when I fitted it.

Martin.

I've tried these cartridges from time to time and I don't think they
are worth it really. On my commuter bike I have an HPX frame pump and
on number 1 bike I just carry a mini pump in my jersey pocket. Once
you get the hang of using the cartridges they work ok, but how many do
you carry; one, two... three? A pump is better solution for me.

One + pump.

Hey, why not get a bike with an engine too so you don't have to bother
with all that tiresome pedalling?

Where does that one come from .. oh right, insinuating that a CO2 pump makes
me really, really lazy.? Not open-minded and willing to try something new,
especially as someone rescued me in seconds after my reliable pump broke.

Personally, I can't see what this has added to the thread. Have you any
personal experience that buying a CO2 pump makes people go out and buy a
motorcycle?

yup, vague memory of useing co2 pumps years ago, my main problem is that
i very rarely (touch wood) get punctures so emergency pumps and tend not
to be used, until i have either lost some part, or its stopped working
or some such.

i used to just use slime on the mountain bike which worked wounders,
going out with friends of recent years has resulted in more aggressive
riding which resulted in snake bites which tended to destroy the tube.

i really should test the wee pump as i've been taking rides out box hill
and i don't fancy pushing the bike home from there!

In the end I just bought a new mini-pump. The old was breaking up, and I
wasn't relying on it anymore. However, is it possible to source some frame
mounts for a truflo HPX pump? When I get my next mountain bike I'd like to
carry that one. [1]

[1] Started the ball rolling with Kona, looks like I had a lifetime
warranty, just need to dig out the receipts. However, I seem to remember it
was an insurance bike, and the third party company just sent me the bike. I
know who they are, so left a message today.
