|This nice little unit will handle either threaded or non-threaded cartridges, and has a Push-to-Inflate valve, so the cartridge won't discharge all at once. The head is designed to work on both presta and schrader valves. Comes with one 16 gram non-threaded CO2 cartridge which will get you to 35 psi for mtb and 125 psi for road. Picture shows the older model.
LickNotes: Note: We recommend using a mini-pump to get things going, and then finishing the job off with the CO2 inflator. Also, beware of frost. If a second shot is needed, make sure you defrost your valve before the second dose.
