Tubolight Insert EVO Gravel

The Tubolight EVO Gravel is a tire insert designed for gravel cycling, featuring a wider and taller profile for improved stability and protection. Its new shape reduces tire contact inside, enhancing rolling resistance and comfort. Made from a firm, slightly harder compound, it supports lower tire pressures without harming the tire or rim. An air channel between rim and insert acts as a passive valve, delaying pressure equalization on impacts to reduce bounce and rolling resistance, improving efficiency and ride feel. Specifications: fits 28" rims (19–25 mm inner width), compatible
