30 grams lighter, 20 percent less rolling resistance: These are the results of revising one of Schwalbe´s most popular mountain bike tyres. With the fast PaceStar Triple Compound, the fine127 EPI-Carcass (previously 67) and the fully modified profile the Racing Ralph´s grip and rolling resistance is much improved. The unique optimum profile specifically designed for 29ers: With the new Racing Ralph the arrangement and spacing of the blocks are specifically adapted to the much larger contact area. The 29-inch benefits lower rolling resistance and increased grip. The new Racing Ralph comes in various sizes and designs. A cross version in size 33-622, GateStar compound for 4X use or as a handmade tubular tyre - Racing Ralph HT (Hand Made Technology) in 26, 28 and 29 inches.
