Unfortunately Performance tyres cannot be 100% protective against punctures without making compromises on rolling characteristics and weight. If you do not want to accept the lowering of the driving quality you need this proven reliable six-part Continental race tube set. It is so compact that you can even carry it in your tricot pocket if you want to. This tube is specially developed for narrow 18-25mm competition tyres with high air pressures. You can choose between the short 42mm tube or the long 60mm version depending on your rim height.
