    What is it?

    Fully threaded valve extenders that work with Removable Valve Core valve stems in both Tubeless and Standard applications.  Included SpeedShields improve aerodynamics while preventing the valve nut from damaging the rim surface.

    Who's it for?

    Cyclists in search of aluminum valve stem extensions that perfectly balance lightweight and strength with an engineered solution that improves valve stem sealing, eliminates rim scratches, rattling and improves aerodynamics.

    Why We Designed It | Product Specs | Getting Started


    Why We Designed It:

    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.

     

    Specifications:

    • High precision CNC machined Aluminum Valve Extenders with full external threads
    • Knurled spherical nuts to eliminate bending load on valve stem
    • Custom molded silicone shield with 3M adhesive backer
    • Less than half the weight of brass valve extenders
    • SpeedShield Improves wheel aerodynamics up to 0.5 Watts at 30mph
    • Limited Warranty

    Getting Started:

    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.

    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..
