The latest tubeless tires have finally matched and in many cases surpassed the best clincher tires in terms of rolling resistance, and they do it with superior puncture protection and ability to run low pressures. \u003c\/p\u003e\r\n\u003cp\u003e\u003cbr\u003eHowever, we've also found ourselves frustrated with overly stiff tapes, weak adhesion to carbon rim surfaces, heavy brass valve stems that imbalance wheels, and worst of all, overly lightweight aluminum ones that are easily broken. While seeking a solution for all of this, the team at SILCA has completely re-thought tubeless as a system with a primary focus on optimizing components for carbon wheels.\u003cbr\u003e\u003cbr\u003eDuring this process, we've developed the world's best tubeless tape for BOTH Carbon AND Aluminum rims: Aluminum Valve Stems that perfectly balance lightweight with strength, and a rim protection system that improves valve stem sealing, eliminates rim scratches and rattling, and improves aerodynamics.\u003cbr\u003e\u003cbr\u003eThese exciting products will allow you to enter the brave new world of tubeless with increased confidence and reduced frustration.\u003c\/p\u003e","published_at":"2016-04-26T12:12:00-04:00","sort_order":"manual","template_suffix":null,"published_scope":"global","image":{"created_at":"2017-06-15T11:44:35-04:00","alt":"","width":576,"height":576,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0309\/9521\/collections\/Silca-Tubeless.jpg?v=1497541475"}},{"id":137445081186,"handle":"tubes-b2b","title":"Tubes","updated_at":"2020-07-01T23:50:04-04:00","body_html":"","published_at":"2019-08-13T13:46:32-04:00","sort_order":"best-selling","template_suffix":"","published_scope":"web"},{"id":82979192930,"handle":"accessories","title":"TUBES, CHUCKS \u0026 VALVE EXTENDERS","updated_at":"2020-07-01T23:50:56-04:00","body_html":"","published_at":"2018-10-11T12:55:11-04:00","sort_order":"manual","template_suffix":"","published_scope":"global","image":{"created_at":"2018-10-11T12:55:35-04:00","alt":"","width":665,"height":665,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0309\/9521\/collections\/21b8ec62-2f1c-4768-a873-00b02900e425.jpg?v=1539276935"}}]

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.
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
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.
