This Lezyne 20g threaded CO2 cartridge delivers fast, reliable trailside or roadside tire inflation without a hand or floor pump. The threaded neck screws directly into any Lezyne CO2 inflator head — no separate adapter needed — for a secure, leak-free seal under pressure.
A single 20g charge is sized for higher-volume gravel and light off-road tires (up to roughly 700c x 40mm or 29 x 1.5"), delivering a quick full inflation in seconds. Compact and single-use, it's built to slot into a saddle bag or jersey pocket alongside a spare tube for emergency repairs.
