Continental Unitube 700x18-25 PV 42mm Race Light Tube

Continental's large range of exclusive race tires is matched by an equally interesting range of tubes. These lightweight Continental Unitube System tubes have the advantage of greater compatibility with more tire sizes. All Continental 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.
