CO2 cartridges -- selection and sourcing

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

CO2 cartridges -- selection and sourcing

I'm ready to make the jump to CO2 inflators, and have a few questions.

First, what do y'all think of the Lezyne "trigger drive" unit?
http://www.amazon.com/Lezyne-Trigger...rds=lezyne+co2



Next, what size cartridges will I need for pumping 700C 25mm tires to ~100 PSI?

Reading threads here, my sense is that I'll need 16g cartridges, or 12g if I'm willing to pump it up to 50 PSI or so with the hand pump first. Any thoughts?

Lastly, the bloody things are expensive. What is the best place to buy quantities of 12 or so? Amazon shows some MOSA cartridges at ~$1 each which is cheap compared to most other alternatives that seem to be ~$3 each. Any downside to the MOSA carts?
http://www.amazon.com/16-Gram-Thread...bxgy_sg_text_b

Thanks in advance!

The threaded work best.. You will need the 12 Gr.

This type works better than the trigger ones.

You use the 12 gram cartridges? I always use the 16 gram, gets me in the 100 psi range in my 23's.

I get 180 psi with the 16gr on 700 X 23 tire.(Number does seem to be high)
140 psi 700 X 28
90 psi 700 X 35

I don't loose any CO2 with the threaded non trigger applicator.

Used it last week on a 100 mile 3 flat ride.

I had one 12gr and two 16grs.

Glass flats at 74 and 78 miles.

Brown Beer Bottles...I hate them.

I prefer the 16g. Having what you need (or more than you need?) is always better than having less than you need.

You guys are doing it ALL WRONG!!

Get an inflator that takes UNthreaded cartridges.

Then go to WalMart and buy a box of a dozen 12g cartridges for 8 bucks.

Do it now and thank me later.

This is my first year (after 45,000 miles) to use CO2. I run tires from 700 X 18 to 700 X 40.
I check the psi after each CO 2 use.

I have seen the Non Threaded cartridges fail about 10-12 times. That is why I went with the threaded and the Non trigger applicator.

I have had 105 road flats plus others at home.

Have fun you All.

Not necessarily. If your only metric is cartridge price, maybe, but if you look at inflator weight, does anything beat this?

I don't think any CO2 inflator beats an Air Chuck.

Does amazon ship to Canada? You can get 20 16m cartridges for 12.99 there.

The issue is that it's co2, not that the company won't ship to Canada.

Should be great.

I will add that I LOVE my Innovations Air Chuck inflator, which looks very similar. It has flow controllable by force down on the chuck so you don't blast it all out at once, and it actually works. The two times I've used it, I've been very impressed - you screw on the CO2, and can fill the tube quickly with small, controlled bursts, while checking for incorrect mounting. I never leave home without it.

The main advantage of threaded inflators is that the head is tiny compared to the non-threaded.

I have one of those genuine innovations heads & buy carts by the 12 pack on Amazon, they work out to be a little over a buck each.

Here's a chart that will show you what pressure you can expect - 16g should get your 23mm tire to 130 psi assuming you get it all in there. Which you won't. it should get a 25mm tire to somewhere in the 110 psi range, which is about perfect.

That's pretty much it - 110 to 130 lbs
