Considerations When Choosing a CO2 Inflator

Inflator Types

You will find that there are three different ways to release CO2 cartridges into a tire. The difference is in the heads of the CO2 inflators. You can either use a press and release design, turn and release design, or unscrew and release design.

All three of these methods work as well as the other, so it really comes down to preference and which you are more comfortable using. However, of the three, the press and release option is probably the easiest to use and more user-friendly. Also remember that it can be helpful if you practice at home first, so you know how to inflate your tires correct; that way, you won't get caught out on the road with an empty CO2 cartridge as well as a flat tire.

Material

A CO2 inflator head will either be made of aluminum or plastic. As with anything, plastic heads make the CO2 inflator cheaper, but it will also be less durable. Aluminum is more durable, so it will last longer, and it is also a lightweight material, so it won't weigh you down as you ride.

CO2 Cartridge Types

A CO2 cartridge will either come in a non-threaded or threaded option. A threaded cartridge is the most common and cheapest than the other version. However, variations. Non-threaded cartridges have a plug-in and play type of design that makes them ready to use by just pushing it into the tire pump. But they are more expensive and not as common as the threaded version.

Inflator Head Type and Size

When considering the inflator head type and size, the most important thing to consider is that you shouldn't get CO2 inflators so small that you can grip them well. Look for inflators that have a nice balance between stability when you are holding it and portability so that it is easy to carry with you.

Frequently Asked Questions:

Which size CO2 cartridge should I get?

You can use either a 12-gram or a 16-gram CO2 cartridge is enough of a road bike. The 16-gram cartridge can pump up 25c tires at 100 psi. If you are concerned about getting two flat tires on your ride, 25-gram CO2 cartridges can be lighter to carry than two smaller CO2 cartridges.

Can you overinflate bike tires?

If you are using the right CO2 cartridge, there should be no risk. Each of the cartridges come with a specific size and air volume, so you should have a basic idea of what the expected tire pressure is from the cartridge. In case you do feel that you have overinflated your tires, remember that you can let some of the additional air out to be safe.

How long does CO2 air remain in a bike tire?

Typically, releasing CO2 should only last a couple of days in your tire. It's important to keep in mind that CO2 is not the same as the air that you have pumped in using another type of pump, which is due to the solubility of CO2 when it is rubber. So, if you do use CO2 in an emergency, you do need to release it all once you get home and then repump up your tires using a regular tire pump.

Should you fully empty a CO2 cartridge into the tire?

Usually, yes, you do want to fully empty the CO2 cartridge when you are inflating a tire. However, you do need to keep in mind the size of the CO2 cartridge you are using and the size of your tire. Also, remember that the volume of the CO2 is fixed, and the larger the tire, the lower the tire pressure will be.
