A 16 g (0.6 oz) cartridge is one inflation, and threaded and bare types differ · review
A CO2 inflator supplied with five 16 g (0.6 oz) threaded cartridges, fitting Presta and Schrader, stated to inflate a road tire to about 100 psi per cartridge.
Our conclusion Fast, and finite. Carry it alongside a mini pump rather than instead of one.
Kadacha’s kit is the complete CO2 answer: head, cartridges and instructions in one purchase.
Everything needed for a flat in one kit. A compact, light head fitting Presta and Schrader valves. Five 16 g (0.6 oz) threaded cartridges. Stated output of about 100 psi in a road tire or about 4 bar in a mountain bike tire per cartridge.
Cartridges come threaded or bare, and the two are not interchangeable between inflator heads. These are threaded, which is the more common arrangement and the more forgiving — a threaded cartridge screws in and stays put rather than needing to be held.
It fills a tire in seconds, which at the roadside in cold rain is worth a great deal. Then it is gone. Each cartridge is one inflation, and CO2 molecules pass through a tube wall faster than air does — so a tire filled with CO2 will be noticeably soft the next day and needs topping up at home with a normal pump.
An expanding cartridge gets extremely cold, quickly. Handle it through a glove or the supplied sleeve; the manufacturers all say so and it is easy to forget in a hurry.

One. Kadacha states a 16 g (0.6 oz) cartridge inflates a road tire to about 100 psi or a mountain bike tire to about 4 bar. A second puncture on the same ride needs a second cartridge.
Most riders carry both. CO2 is fast and finite; a pump is slow and unlimited. Carrying only cartridges means a second puncture ends the ride.
7.8/ 10
Fast, and finite. Carry it alongside a mini pump rather than instead of one.
