Portable CO2 Cartridge Inflator

What is a CO2 inflator?

In a basic sense, they're just a small cylinder of compressed Co2 that's fed through the valve head to your tires. There are different variations on this theme, but they all have the same goal. Almost all of the rounds use threaded rounds, so that's what we feature here, which are available in 16g or 25g versions.

The two basic types are inline, whereby the cartridge is in line with the valve and actuated by pressing down, and angled types where the valve head forms a 90-degree angle and the cartridges will stick out sideways from the rim when in use. There’s no great difference between the two, but if you’ve got small wheels and lots of spokes then an angled one might be easier for you to use.

How many bullets does it take to fill a tire?

For road tires, a single 16g cartridge is enough to re-inflate and will make it reach and exceed the pressure you want with ease. You may eventually overinflate and have to back off.

For larger tires, we're talking gravel bikes here, and we'll need a larger 25g cartridge. While you may have the volume to re-inflate within 16 grams, you may not be able to reach enough pressure to remount your tubeless tires, leaving you in a bind.

Can I use a tubeless CO2 inflator?

In general, yes, although some sealants say otherwise. This problem comes with the freezing effect of releasing compressed gas, which can freeze your sealant solid, rendering it useless. The best course of action is to rotate the valve to its highest point and inflate it from there, allowing the liquid sealant to drain to the bottom, as far away from the icy blast as possible.
