Where do you buy your CO2 cartridges? (Group buy)

cdaly_ · 11-03-2010 06:07PM #1

Just wondering. A pair of 16g screw in cartridges from cyclesuperstore cost about €8 while http://www.co2cartridges.co.uk/eu/ will ship 30 of them to Ireland for about GBP30 or 300 of them for GBP180...

Are 16g what you need or will 12g do?

blorg · 11-03-2010 06:16PM

I got a stock of them from Planet X at 84p each when I was buying a bike anyway.

30 for £30 sounds good, you could get a few people together on that one.

You want 16g for full pressure.

Lumen · 11-03-2010 06:17PM

Nice find! Presumably they're surface shipped?

Group buy?

12g are a bit marginal, I use 16g.

I want a musket now.

Chips Lovell · 11-03-2010 06:19PM

A musket? I had to ask.

if it's a group buy, count me in

Chips Lovell · 11-03-2010 06:28PM

Does one need an adaptor thingymagjig for these? I've only used one once, which was borrowed from someone else. Froze my hand to the bloody thing.

Yes, you need an adaptor. AFAIK there are basically two types of canister, threaded and unthreaded, and different capacities (specified in g), and that's it.

Mine is threaded, I assume this is more common?

Chips Lovell · 11-03-2010 06:37PM

What the hell so, I'll go in for a few if someone organises a group buy.

Nietzschean · 11-03-2010 06:38PM

CRC used to have both types, unthreaded are cheaper..but threaded have smaller delivery systems(unthreaded have to hold the cartridge in place)

blorg · 11-03-2010 06:39PM

Most are threaded, you only need an inflation head which is tiny. Some people use an all-in-one pump, these are much bigger but include a pump. Need to use gloves when applying all right.

The all-in-one pump is handy for clinchers, because you can frame mount both the pump and a canister and carry patches for when you run out of tubes.

I guess it makes no sense for racing with tubulars, since you have a limited number of reinflation opportunities determined by the number of spare tyres you are carrying (most likely zero or one, and maybe an extra canister to top up after using gunk?).

when crc had them it was 2 - 3x cheaper for unthreaded..you don't need gloves too i guess is a bonus, but mine is alot bigger than yours alright.

On this site they appear to be the same price...so I think its time for a tiny lil threaded thingy for me.

Chips Lovell · 11-03-2010 06:45PM

To be honest, even with a few cartridges, I'd still leave the pump strapped to the frame. It's pretty unobtrusive and handy for back-up in the even to multiple punctures or CO2 cock-ups.

I always carry a pump but gentlemen, it goes in the jersey pocket, you know the rules.

That's just a different class of failure. Do pros ride with a pump sticking out of their jersey? No. So it's not Euro.

Team car FTW.

The only pumps that can fit easily in a jersey pocket aren't worth a toss anyway.

EDIT: Oh yeah. Blorg. Pot. Kettle.

I'd disagree, I have a Topeak that certainly works, it is a pain in the neck (why I carry CO2) but as a backup it is fine; it will certainly get me home (or around another 150km of a sportive) after 5 minutes of pumping.

I carry it in the jersey mainly as it didn't come with 10 frame mounts.

cdaly_ · 11-03-2010 09:04PM

Errm, what about the notion of carrying a pump so you can test if you repaired the darned thing right in the first place before breaking out the canister? Or do you all just swap over tubes and patches be damned?

Right. If I can get 9 takers, 30 x 16g cartriges comes out at EUR17. Less than 9 takers and the price per 30 starts to go up due to shipping. More than 9 and the shipping jumps again.

Any takers?

Chips Lovell · 11-03-2010 09:06PM

So we're each buying 30 is it?

What's the best way of sorting you out if this happens? Paypal?

Swap over tubes, if you are going to patch and wait for it to get tacky to do properly then you are hardly a prime candidate for CO2. With practice you can fix a puncture in 2 mins with CO2 and a tube swap. Tubes you can get for under 2.50 in bulk, you can either keep them and patch later or throw them. Advisable to keep if you are early in a long cycle BTW whether you eventually patch or not, I have certainly regretted throwing them.

cdaly_ · 11-03-2010 10:46PM

My prime reason for CO2 is the can't-get-decent-pressure-with-a-pump one. Have 10 tubes from CRC for EUR22 just arrived so I guess I'm ready...

@el_tonto: Cash, cake? I've not received money by paypal thus far. Don't they charge you for that?

Gavin · 11-03-2010 10:50PM

Sign me up for some screw in canisters! Handy on the commute too. The freezing thing is a bit of a problem with both schrader and presta valves. For presta you just squash the yoke on and squeeze, but then the valve is freezing and it's quite fiddly screwing the locking part back in. With schrader you have to screw the head onto the valve and unscrewing it is also bloody awkward with the freezing head of the sprayer. All very confusing.

DirkVoodoo · 11-03-2010 10:54PM

Yeah count me in for some threaded.

I carry a pump too, you can give the tube a small bit of pressure to give it shape and make mounting it on the rim easier, then blast it with the cannister.

CheGuedara · 11-03-2010 11:10PM

Sign me up for a lot 30 of threaded too - that's a very good price!

Most MTBs these days are presta surely?

EDIT: At OUR level. Yak.

cdaly_ · 11-03-2010 11:48PM

OK so. We're looking at a box of 30 x 16g threaded CO2 cartridges for about EUR17 based on 10 takers (including myself). Shipping costs change in jumps so the price per box will depend on the numbers.

Thus far we have:

@was that a yes? Lumen?

@Lumen, can you edit the thread title to include a 'group buy'?

Nietzschean · 11-03-2010 11:50PM

yes i'm in

blorg · 12-03-2010 12:10AM

I have lots, I don't need more!

Where do you buy your CO2 cartridges? (Group buy)
