CXWXC 16g / 25g Threaded CO2 Cartridges or CO2 Inflator for Bike Tires - Cartridge for CO2 Inflator with Threaded Connection, CO2 Pump for Road and Mountain Bikes

perfect for bring with me on my bicyclethank you

Nice for travel bike bag to repair flats.

I bought these for my planted aquarium’s first co2 system, and they fit perfectly! I recommend using 1 bubble per second or the cartridge will run out in less than 6 hours, I’m already on my second one and it hasn’t even been a full day.. but after figuring it out I’m confident that it will last for a little over two weeks!The metal is high quality and sturdy, the threads are as they should be. My plants seem to be responding to this co2 already! I bought this as an emergency replacement after my first co2 cartridge leaked everywhere, and I personally would not buy again as it’s not worth it in the long run.. but this is great if you need co2 on a budge!

Perfect for any cyclist. Light. Not bothersome. The “ get me home “ cartridge. It’s a must.

Good quality cylinders. They hold up to my off road abuse and deliver when needed.

Using them in a inflatable life vest. Seems to work fine. I weighed them and they weigh correctly as well

They work. Best of all, not a ripoff like the PRO BIKE TOOL cartridges.

Perfect size for inflating a 29 x 2.40 MBT to 40 PSI
