For quick and efficient tyre inflation, CO2 inflators take some beating - no pumping and sore arms, just attach the valve and release the gas to inflate. With an adjustable outlet valve, this inflator from Zero12 lets you control the gas release so you can be sure to inflate your tyres and not waste the precious gas. Compatible with Presta and Schrader valves, this inflator is suitable for road, MTB or BMX use. As well as providing storage for a CO2 cartridge, the housing also keeps your hands away from potential hand freeze during inflation. Suitable for use with threaded or unthreaded 16g cartridges, finding replacements will be easy should you run low.
