16 Gram Threaded Co2 Cartridges (Pack of 30)

Great

I was running low on CO2 cartridges for my mountain/road bike and the prices were outrageous at my local bike shop and REI. I even tried Walmart and it wasn't much better. Enter the Mosa 16g threaded CO2 cartridges. They arrived in a plain box and the cartridges were not labeled. I inspected cartridge and I none of them had any sharp edges or burrs. I also tested two of them in my garage and they worked perfectly with myLezyne Trigger Drive CO2 Inflator Lezyne Trigger Drive CO2 Inflator (Black). Now I have a huge stash that will last me a while. I would definitely purchase these again when I run low. Such a great value!

There are things in life that are worth spending extra on for high quality and name brands, and then there are CO2 cartridges. I use these to fill bike tires when I flat on the road.All of my cartridges threaded fine, and I've now had to use two out on the road. They worked exactly as they should.Just a heads up: CO2 leaks out of tubes faster than air (which is mostly nitrogen). It'll last you about a week before diffusing too far, but a tire filled up with CO2 should probably be re-filled by a pump when you get home!

I bought these cartridges as replacements for name-brand ones, used as a tire inflator for my bicycle in case of a flat.I chose these based on two criteria: 1) they were threaded and 2) value. The product is true to description. With S/H, each cartridge ended up costing approximately 1.33/cartridge. The cheapest I could find at REI was 2.00/cartridge.Anyway, the cartridges came to me inside a bubble-wrapped USPS bag, which was inside a UPS box (or was it the other way around?) -- I don't remember. No box, no brand labels, no thing. They're just in there, banging around, making clinking noises as I brought the box inside.Upon inspection, the cartridges seem to be fine and are housed in a metal shell. As mentioned, there is little useful markings; indicating CO2 amount (16 grams).I sacrificed one as a test and I am glad to report that they worked at filling my bicycle tire, as expected. All in all, though I don't really like the way it was packaged (which should have been better since the S/H charges were 1/3 of the total price of the product), and that there is little glamour (none is needed), it is functional (all that matters) and because it is the best value I have found, I do not regret buying these!

I had some reservations about ordering this after reading some other reviews that mentioned damaged threads and mysterious packaging but the price is so much better than brand name CO2 cartridges for bike inflators that I figured I'd take the chance. The item came in a normal looking but unbranded box that clearly indicated what was in the package and had normal warnings. In other words, there was nothing mysterious about the packaging, it was just generic. I inspected the threads on all 30 cartridges very closely and there is no stripping or damage to any of them. Since my bike happened to have a flat tire anyway, i replaced the tube and tried out one of these cartridges instead of my floor pump just to see if they worked (I didn't want to end up 30 miles from home some day and find out that the treading didn't match my inflator). It filled up completely with one pull of the trigger. Previously I had used non threaded 12g cartridges which my inflator also works with, but b/c they were non threaded, there was always some leakage and so I'd have a hard time getting a 700x23 tire up beyond 80 PSI (I usually ride between 100-110 PSI). After I inflated the tire, i used a pressure gauge and found that it had inflated the tire to 169 psi. It worked so well that I actually had to let air out of the tire to get it to the right level. I'm very happy with this purchase. 30 of these will last me several years and easily saved me $50 or more over that time compared to buying the 2 packs from the bike stores.
