The new ContiTube tube program makes it even easier for you to find the optimal tube for your needs. The particularly clear and user-friendly tube system has been perfectly adapted in size, design, valve type, and length to the respective tire dimensions and intended uses. With different tube types, you can also influence the riding characteristics of your bike with minimal effort: The standard tube, available in all dimensions, offers the best compromise for everyday requirements. Weight and rolling resistance can be noticeably optimized with Light and Supersonic tubes. However, the reduced wall thickness down to 0.45 mm increases the risk of punctures. Additionally, lightweight tubes need to be inflated more frequently. On the other hand, the Hermetic-Plus tube is a worry-free product. Thanks to an improved formulation, it is now more compact and lighter, with an increased butyl content and higher wall thickness that make it particularly puncture-resistant. Because it also holds air for an extended period, it is a favorite among many bike rental companies. Our Freeride and Downhill tubes are also particularly strong and voluminous. They effectively protect against pinch flats with their extra-thick wall.
