The Schwalbe Durano DD Road Tire is a reliable all-around training tire that incorporates Double Defense technology to ward off punctures and sidewall damage. Beneath the dual-compound rubber that offers an optimal balance between rolling resistance and traction a RaceGuard protection breaker keeps foreign objects from penetrating the tread while at the edges monofilament Snakeskin fabric reinforces the sidewalls to prevent cuts and minimize the risk of pinch flats.
