Higher Volume Threaded CO2 Refill For Gravel Tyres

Overview

The Lezyne 20G CO2 Cartridge is made for riders who need a larger inflation charge than a standard road cartridge. It is a practical refill option for gravel, hybrid and similar higher-volume tyre setups.

Suitable for Gravel Tyres: The 20g cartridge contains enough CO2 for higher-volume tyres such as 700c x 40mm or 29" x 1.5" sizes. This makes it useful for riders who need quicker inflation after a puncture repair on bigger tyres.

Threaded Lezyne Fit: These cartridges are threaded for secure use with all Lezyne CO2 inflators. The threaded design helps create a reliable connection, making inflation more controlled during roadside or trailside repairs.

Easy Ride Carry: The cartridge is compact enough to carry in a saddle bag, frame bag, tool bottle, or jersey pocket. Keeping one or two spares with your repair kit can help you get back on the ride faster.

The Lezyne 20G CO2 Cartridge is a threaded refill cartridge for quick tyre inflation on gravel and other higher-volume bicycle tyre setups.
