Continental Inner tube Presta 29 x1.75-2.50

The benefits of the Continental Unitube system Multi-size tubes allow for greater compatibility with more tire sizes, and fewer tubes. Unitubes are available in 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 greater reliability at the valve stem. Each tube passes a rigorous 100% quality control inspection.
