Why Do Cyclists Trust the Planet Bike 25g CO2 Cartridge?

The Planet Bike 25g Threaded CO2 Cartridge is the go-to roadside inflation solution for riders who want to get back on the bike fast. The threaded design locks securely onto compatible CO2 inflators for a leak-free connection, and the generous 25g capacity handles road tires, gravel tires, and even larger-volume mountain bike tires without breaking a sweat. When a flat strikes mid-ride, this cartridge delivers a full, reliable inflation in seconds so you can get back to riding.

Compatible with any standard threaded CO2 inflator, this cartridge comes ready to use straight out of the packaging with no prep required. At 25g, it's the higher-capacity option compared to the more common 16g cartridges, making it the smart choice for tubeless setups, larger tires, or riders who want the peace of mind that one cartridge will finish the job. Toss one in your jersey pocket or saddle bag and stop worrying about flats.
