The Challenge threaded inline valve extenders add length so that your valves will protrude through deeper dish rims, allowing you to attach a pump. They are compatible with inner tubes and tubular tires that include removable valve core Presta valves. They also include rubber gaskets for an air-tight fit. The kit includes two black anodized aluminum extenders and a plastic tool.
