This Marathon is a dream. Incorporated in it is all of Schwalbe’s Evolution Technology: High Density Guard. The safest protection belt for light weight tyres. SnakeSkin. Much lighter than a rubber sidewall, but just as robust. RoadStar- Triple-Compound. Our best rubber compound for outstanding grip, easy rolling and long life. We combined this high quality technology with a classic, versatile tread, which feels at home on any road: The Dureme is a breeze on tracks and rolls phenomenally easily on the road.
