At Schwalbe, the abbreviation DD stands for Double Defence. In addition to the RaceGuard protection belt, a layer of snakeskin fabric strengthens, in particular, the shoulder and side wall of the Durano DD ensuring all-round protection combined with minimum additional weight. The snakeskin fabric is new. Now, a monofilament fabric is used that provides even better cut resistance and greater snakebite protection.
DOUBLE DEFENSE RACEGUARD Combined puncture protection. Under the tread and on the sidewalls. In the Race-version a tire is protected by all around SnakeSkin and RaceGuard (under the tread).
PERFORMANCE LINE Excellent quality for intensive use. These are the best value for money tires.
