High volume CO2 inflation

These inflators are specifically designed to handle 20g CO2 cartridges. While standard 16g canisters are common for road bikes, the 20g size provides the extra volume needed for gravel and mountain bike tires. This capacity ensures you reach a rideable pressure without needing multiple smaller cartridges.

The collection includes standalone heads and complete kits. Most models feature a compact footprint to fit inside a jersey pocket or a small saddle bag. These tools prioritize speed and efficiency during a flat repair.

Valve compatibility and hardware

Most 20g inflators utilize a threaded connection to secure the cartridge. This prevents gas leakage during the discharge process. The heads are typically universal, allowing for quick attachment to different valve stems without swapping internal parts.

Deployment and safety

When using these high-volume inflators, ensure the cartridge is fully pierced before opening the valve. The rapid release of CO2 causes the canister to freeze instantly. Use a sleeve or gloves to protect your hands from cold burns during the inflation process.

Check the brand pages for Lezyne or Genuine Innovations to see specific head designs. Some models offer a 'click' engagement or a push-to-inflate head that simplifies the connection when you are working on the side of a trail.
