Lezyne CO2 Cartridge Refill

If you're like most triathletes & roadies, and prefer CO2 to a frame pump, then Lezyne is the obvious way to go. Featured here are threaded 16g CO2 cartridges for use with all Lezyne CO2 inflators. It inflates 700c road tires to around 120psi (8.3bar), or one 26-inch mountain tire to 30psi (2.1bar). So, as long as you remember to bring one along with your essentials, you'll never be stranded with a flat again.
