Specialized Airlock Presta Valve Tubes

Unlike traditional sealants that can pool at the bottom of the tube over time, the Airlock formula is integrated into the tube's construction. This homogenous design ensures the sealant remains evenly distributed, providing consistent protection without causing balance issues or weight imbalances.

These tubes are compatible with any clincher tire system that uses a Presta valve. You simply need to match the tube size range and valve length to your specific tire width and rim depth.

No, these tubes come pre-filled with a non-separating formula designed to last for the life of the tube. There is no need to inject additional sealant or perform maintenance.

While they contain integrated sealant, they are engineered to be a lighter alternative to traditional heavy-duty puncture-resistant tubes. They offer a balance between flat protection and rotational weight, making them a practical choice for daily riding.

The Airlock sealant is designed to handle most common road debris like thorns and small glass shards. If you experience a larger tear that the sealant cannot seal, you can patch the tube as you would a standard one, or replace it if the damage is significant.
