SILCA LIMITED WARRANTY
Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use. SILCA guarantees the life of these items to be at least 2 years from the date of original purchase.
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.
