AIRLOCK System
Airlock tubes feature a built-in sealing system that coats the tube for permanent protection against punctures. Not only that, but the sealant is designed to work continuously to prevent small leaks, so you won’t have to worry about getting a flat tire when riding on any terrain. Thanks to its uniform composition, the sealant won’t clump, and the tube/tire combination will perform just like it did on day one.
