In stock by popular demand. The OEM Zipp valve extenders install over an open Presta valve. The Zipp valve extenders are precisely made and feature a 3mm hex broach in the barrel to guarantee a perfect seal when tightened and a raised, machined head with a slight bevel to ease installation of the pump head.
Please note: valve extensions require careful installation, so Zipp highly recommend's pre-installing them on your spare tires and tubes before your race. Return to Top
