DD stands for double defense. Schwalbe's Ultremo DD has puncture protection under the tread and "SnakeSkin" fabric reinforcement embedded in the sidewalls. This reduces the incidence of punctures, sidewall cuts, and pinch flats. Outside, the RaceStar Triple Compound tread features a fast-rolling center section with softer and stickier sides for sure cornering.
