Made from high-density polymer foam, which ensures a long product lifespan, it allows riders to confidently tackle even the most challenging trails and terrains. The Airliner provides a robust barrier between the rim and the tire, offering unprecedented protection against punctures, sidewall slits, and pinch flats. 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 even the most demanding terrain with ease. The Air-Liner Protect e-Bike is an innovative tire insert specifically designed for electric mountain bikes. This product is engineered to withstand the challenges posed by the higher weight of e-bikes. Compatible only with tubeless tires and only with multiway tubeless valves – a 40mm valve is included in the scope of delivery.
