The Schawalbe Durano Rigid Tyre is for mile eaters. Why? because no other racing tyre lasts longer. At the same time the Dual Compound offers greater grip for training on wet winter roads. It has a proven RaceGuard protection belt.Under normal conditions - i.e. unladen, on-road and under ordinary braking - expected tread life should be over 6,500 miles (10,000km).
