Made from high-density polymer foam that ensures a long product lifespan, it allows riders to confidently tackle even the most demanding trails and terrains. The Airliner provides a robust barrier between the rim and the tire, offering unparalleled protection against punctures, sidewall slashing, and crushing. The Air-Liner Protect has been carefully designed to reduce unnecessary weight from the tire and wheel system. With its new “T”-shaped design, Air-Liner Protect offers improved shock absorption, allowing you to navigate the toughest terrain with ease. Both versions are only compatible with tubeless tires and only with multi-way tubeless valves – one valve is included in the scope of delivery. Air-Liner Protect has the same shape for enduro and downhill but differs in density.
