CO2 inflators for bicycles are compact and efficient tools used to quickly inflate tires with compressed carbon dioxide gas cartridges. They provide a portable and rapid solution for inflating tires during roadside repairs or emergencies.
When considering a CO2 inflator, it's essential to check the compatibility with your bike's valve type, the size and quantity of CO2 cartridges needed, and familiarity with using the inflator before relying on it during an actual emergency. Additionally, having a backup plan like a hand pump or spare CO2 cartridges is advisable for longer rides or in case of multiple flats.
