Alloy Valve Extender Kit 41.5mm

The Challenge threaded inline valve extenders add 41.5mm length so that your valves will protrude thru 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 alloy extenders and a plastic tool.
