Crankbrothers CO2 Cartridge

The Crankbrothers CO2 Threaded Cartridge is a convenient and reliable solution for quickly inflating tires while on the road or trail. Available in 16g, 20g, and 25g sizes, these cartridges provide a controlled burst of CO2 to reinflate tires efficiently, with the appropriate size chosen based on the tire volume. Smaller 16g cartridges are ideal for road bike tires, while larger 20g and 25g options are better suited for high-volume gravel and mountain bike tires. Sold individually (without a CO2 inflator), this compact and portable cartridge is a must-have for cyclists seeking a quick and effortless fix for flat tires.
