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.

Birth of the cool. Sorry Miles.
It's amazing how a simple object can work so well. Speedshield not only works, but also looks cool, and ain't that what really counts?

Good quality, do the job
These extenders are well made, they look nice because of this aero rubber support. Perfect length for my 65” wheels. No rattling noise.

Great product, looks very nice.
Extenders are of very high quality, work great with threaded nut. Not sure if there any benefit from the SpeedShileds have, but they look awesome on the carbon wheels. Keeps everything in place, no rattling. Highly recommend if you want a little extra bling..
