A sure way to ruin a ride is getting a flat tire. A CO2 cartridge is a quick and easy way to re-inflate your tire after replacing your tube. These 20g threaded cartridges simply screw into a CO2 inflator (sold separately) and will get you back on the road (or trail).

A 20g CO2 cartridge contains a mid-sized charge suitable for all road tire or higher volume gravel tires or similar (Exp. 700c x 40mm / 29" x 1.5"). See the CO2 Inflation Chart for more details.
