Full to the brim.

Not all CO2 cartridges are the same, and for an item that can make the difference between continuing a ride and making a phone call for a bail out, you'll want a cartridge that has been certified for safety. Silca's Ultra-Premium CO2 Cartridges are so well-designed they are used in life vests and airbags.

While 16-gram cartridges are only required to hold 14 grams of CO2, Silca ensures that its cartridges hold 15.5 to 16 grams so that you'll get the maximum fill with each use. They are ISO, TUV, and RoHS certified and are also used in military and aviation life vests and avalanche bags.

The Silca Ultra-Premium CO2 Cartridges come in a two-pack and are 16 grams each.

CO2 Cartridges

  • Familiarity: I've used it several times

Yep, these are threaded CO2 cartridges, that function as they should.

CO2 when you need it

  • Familiarity: I've used it several times

CO2 pumps and canisters have all but eliminated the need for hand pumps.
They are light, small, and reliable. I've been impressed by the functionality of CO2 systems now-a-days. I used to think people that only carried CO2 on mountain bike rides were asking for trouble. Now I only take a hand pump on the longest rides in remote places. These CO2 work so well I even keep them with me on my DH bike.

Nice To have

  • Familiarity: I've put it through the wringer

I carry a CO2 cartridge and inflator on all of my rides. Nice to have if you burp a tire or get a flat.

Packed with Carbon Dioxide

  • Familiarity: I've used it several times

These little cartridges come packed to the brim with carbon dioxide which you can use to inflate your tire after a devastating flat. It is pretty neat.


  • Familiarity: I've used it once or twice and have initial impressions

I carry a bomber frame pump so I use these in an emergency and nice to have them in my pack. I've used Silca products for a long time so I won't be surprised that these will work just fine.

Psssst. (oh no!). PFFFFFFFFT! (oh yeah!)

There are CO2 cartridges and then there are CO2 cartridges.

Surprisingly, when you buy a CO2 cartridge, the size is the maximum amount of CO2 that's actually being held. By law, a 16g cartridge only has to have a minimum of 14g inside, and many other cartridges trend to the lower end of the 14-16g range.

Silca insures that all of their cartridges have at least 15.5g of CO2 inside, so you get maximum inflation for a given size when using Silca cartridges.

Silca also makes the world's best floor and frame pumps, so I expect nothing less from the CO2 cartridges and inflator (sold separately).

Never had any issues with these cartridges. They come in nice packaging, and always work when you need them, not much more you can ask for.

Reliable C02

  • Familiarity: I've put it through the wringer

Come in two, not all that expensive and work every time. Use them on the road paired with a Lezyne Pressure Drive CFH pump, and they've never failed me before.

Easy is best

  • Familiarity: I've put it through the wringer

I have been using these cartridges all summer and they work very well. Considering how affordable they are I would have to say they are the best value cartridge on the market.

Compared to the innovations cartridges I have used these 16 gram cartridges seem to hold more CO2. This is nice when you are using them to inflate a tire larger than a 26 inch tire. These will completely fill my 650b tires and in some cases I still have a little left in the cartridge for a top off. Some of this will be determined by how high you run your pressure and what tires you are riding. Must say I am very happy with these cartridges and I will continue to purchase them.
