Forgot how good CO2 is

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

If you pull out a mini pump on a group ride you deserve to be LFD.

i carry both; a cartridge for group rides and a pump for a second flat or when I'm alone.

So many doohickeys for a bike ride.
How did people manage back then.

I mean really, CO2 cartridges are the wrong thing to try to make an environmental point on.

And I carry three with me, and I've never had a failure. I have, on the other hand, had a Road Morph head blow apart on me, so there's that.
Perfect.
Who the **** said anything about reasons for using CO2 are wrong?!
And I doubt anyone has gotten their tire to 100 psi with a mini or frame pump.
I know I'm gonna get testimonials to the contrary, but unless I see it, I aint buying.

The CO2 in cartridge form is manufactured for other purposes, e.g. airsoft, soda, CO2 dragsters (I remember that from highschool). CO2 itself is used for other things, such as dry ice.

Bike tire inflation is probably a tiny slice out of all those uses. If we must worry about stuff like that, we should also get concerned with what the rubber plantations are doing to the environment, what the metal extraction / plastic creation is doing to the earth, etc etc...

Yeah, but like I said I rarely get a flat and have never made the call except the times I crashed hard or was hit by a car. And it would be three flats because I carry two cartridges.

But if I do get more than two flats I'm saying **** it, it's not my day. YMMV.

Topeak Road Morph is great. Currently have a Lezyne mini. Fits great on the jersey but never able to the full pressure. Gonna get a Topeak once the Lezyne eats it. Long on the jersey pocket but oh-so reliable. Don't have to worry about canisters of carbon clinking around on a jersey or stuffing a saddlebag either.

I don't think CO2 is environmentally bad or elitest or anything else. I just don't mind pumping them up manually. If it's wet and cold I may still use CO2.
I can suffer pretty bad on the bike too, but that's fun.

Pumping a tire to 100psi with a hand pump in the middle of a ride sucks. If anybody stops and waits for you , it sucks even more.

If hand pumps really werent' that big a deal, people would just use them at home instead of buying a floor pump. Alas, they suck compared to floor pumps (and CO2).

One gallon of gasoline results in approximately 3000g of CO2 emitted, so is equivalent to 187 16g CO2 cartridges, which makes one cartridge about comparable to combusting two tablespoons of gasoline. Basically, a lifetime of fixing flats might compare to driving a single errand. (Yes, there is some manufacturing involved in making CO2 cartridges, but gasoline doesn't magically appear at the pump either.)

Methane gas is worse for the environment than C02. That means that a burrito is more hazardous to the Earth than a C02 cartridge.

Burritos, cows, etc are carbon neutral. Things that grow use carbon from the atmosphere, which then gets released back when you or something else living consumes it. It doesn't affect the total amount of carbon in the cycle - hence its neutrality. The only thing it affects is the rate of the cycle. Gasoline (and CO2 carts) release carbon that wasn't there already, so adds to the total amount in the cycle.

Seriously, if you're complaning that you're ruining the environment by buying CO2 cartridges for your bike inflation needs, you need to seriously re-examine your perspective and priorities.

As said above, you'd better not be driving your car on a single needless errand for the rest of your life, or never take another airplane trip ever again if you think that you're optimizing so well that you need to worry about the amount of CO2 involved with the cartridges.

Your google searches in a week definitely exceed the CO2 emissions from that 16g cartridge.

Not lessening CO2 emissions. The CO2 comes from the air. It is not made especially to load into the cartridges. So it just ends up where it started. If you recycle the cartridges, not terribly much to complain about emvironmentally. If you subtract the CO2 that you wouldn't generate from effort to pump up the tire, the picture looks even better.

I keep my house at 71 in the summer, drive a pickup 14 miles round trip to work everyday, and have a huge TV.

And I use CO2.

He is not talking a out the CO2 that results from the burrito but the methane. Do you need it spelled out for you? Think frijoles!

My point is that methane is a more dangerous green house gas for the environment than CO2.

Just for clarification, CO2 doesn't come from the air. It ends up in the air from burning hydrocarbons (gasoline, natural gas, oil, etc.). The CO2 in the cartridges most likely came from the manufacture of hydrogen, where CO2 is a by-product. There are also reservoirs with high concentrations of CO2.

Researchers are trying to develop processes that remove CO2 from the atmosphere (air), but it's very difficult since the CO2 is at such a low concentration (~380 ppmv) and there's no pressure driving force.

I used to work on developing processes that removed around a million tonnes of CO2 per year. We'd need thousands of these types of plants to make a difference in the amount of CO2 in the atmosphere. So please do the math and see if the amount of CO2 in a 16 oz cartridge makes a difference.

The ONLY thing I don't love about CO2 is that the tyre is flat the next morning... so now when I get home I typically patch the tube and put it back on the bike filling it with N2... and put the spare back in a Ziploc for the next ride, replacing the 16g CO2 I used.

CO2 is too cheap when purchased in bulk. I pay less than $1 each and the 32 count case I picked up last year will likely last till I buy a new bike!
