The new ContiTube bicycle tube program makes it easier for you to find the ideal tube for your cycling demands. The user-friendly tube system is suitable for any size, length, design, type of valve and perfect for any tire dimension and riding occasion. Varying tube types can affect your tires’ handling characteristics: the Standard tube, available in all dimensions is the best choice for everyday cycling whilst Light & Supersonic varieties give racers the option of lower rotating weight, therefore increasing speed. The lightweight tubes have a lower thickness and so it is imperative that inflation pressures are maintained to prevent the risk of pinch flats.
