The advantages of the Continental Unitube system

• Multi-size tubes allow greater compatibility with more tire sizes, and fewer tubes.
• Unitubes are available in both Schrader and Presta valve tubes. Presta valves are available in a variety of lengths.
• All tubes are seamless and mold-cured (vulcanized) to ensure uniform roundness and improved reliability at the valve stem.
• Each and every tube passes a stringent 100% quality control inspection
