Limited Warranty

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.

    You get what you pay for!

    Yes, they're expensive. Yes, the little "Speed Shields" ad a modicum of weight (and potentially imbalance your cost-no-object wheels.) But they are ROCK solid, allow NO air leak, and insure silence on any tube / tire / wheel connection. I first experienced these when they were packaged with my Silca latex tubes. When a set of my tubulars needed new extenders due to getting gunked up with a little too much sealant (yes, I run an ounce of sealant in my tubies) I went for these. As usual, Silca delivered, just like they do with their wax products and tubes. #HappyCyclist

    Rattle Gone

    Perfect for stopping that pesky valve stem rattle from carbon wheels. SpeedShield works great!
