Most carbon rim profiles require valve stem lengths longer than what is typically referred to as standard. Those longer valve stems have significant weight that can unbalance the wheel at high speeds. SILCA Threaded Valve Extenders are lightweight aluminum that provide a significant weight savings over a full-length brass valve stem. The SILCA extenders come with SpeedShields and spherical nuts that protect the rim, prevent rattle and improve air flow.
The SILCA Threaded Valve Extenders with SpeedShield are ready to use when removed from the package. If you would like to learn more about features, functions and maintenance of the Threaded Valve Extenders with SpeedShield, please visit the SILCA resource center.
