Vittoria's Removable Valves are something special. They're not valve extenders like you'd expect, but actually valve stems that function with Vittoria's 320 TPI tubulars and Rubino Pro tubulars. These tires and tubes have unique removable stems. Simply un-thread the valve stem that is not the preferred length for your rims and screw on a new one. This way, you can ensure that you have a single-piece stem at the proper length for easy inflation and with an accessible valve. With an exposed valve, you'll be able to tighten it to prevent leaks or open it fully to inject liquid sealant inside the tubular tires on your deep carbon rims.

Note: These valve extenders only work with Vittoria tubular tires
