Lezyne Tubeless Plugs

Unlike traditional sticky tire worms that are inserted from the outside, these mushroom plugs are designed to be installed from the inside of the tire. This creates a more secure, permanent seal that is less likely to pull out or leak under high pressure.

While these are highly effective, they are primarily designed for home or workshop use because they require the tire to be removed from the rim to apply the rubber cement and abrasive pads properly. For quick, mid-ride fixes, a standard external plug tool is usually more convenient.
