Made from high-density polymer foam that ensures a long product lifespan, it allows drivers to confidently tackle even the most challenging tracks and terrains. The Airliner serves as a robust barrier between the rim and the tire, providing unparalleled protection against punctures, sidewall slashes, and pinch flats. The Air-Liner Protect has been carefully designed to reduce unnecessary weight from tire and wheel systems. With its new "T"-shaped design, Air-Liner Protect offers improved shock absorption, enabling you to navigate even the toughest terrain with ease. Both versions are only compatible with tubeless setups and multiway tubeless valves – one valve is included. The Air-Liner Protect has the same shape for Enduro and Downhill but differs in density.
