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":82979192930,"handle":"accessories","title":"TUBES, CHUCKS \u0026 VALVE EXTENDERS","updated_at":"2021-02-28T02:35:19-05:00","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"}}]

The highest quality valve cores for presta valve stems which use removable cores. These can be used to upgrade or replace your existing valve cores in tubular, tubeless and high end clincher inner tubes.
Highlights:
100% CNC Machined brass valve cores with roll formed threads for higher strength
Tighter tolerances allow for increased airflow and better tolerance of sealant and contaminates
Full synthetic seals resist aging and are more resistant to damage from sealant
So we've always noticed how really expensive tubulars had such nice valve cores with smooth edges and high quality seals that resisted sticking. When we started developing SILCA Tubeless valve stems, we set out to find the best cores, and realized that only a handful of companies make them globally. After a lot of phone calls, emails and discussions, we knew instantly when we had found the ones we were after. Fully CNC machined with roll-formed threads these cores give themselves away with their spun-formed tops that keep the valve nut from unthreading too far. Most companies crimp the threads here which damages them such that the nut cannot thread over..we find the extra effort to spin form a perfect little mushroom head on the top of the valve to really say it all: these are carefully made. Icing on the cake is the use of fully synthetic seals for both the stem seal and the core seal, this means that the core will resist aging and cracking for far longer while being significantly more resistant to both synthetic and natural based sealants if you are using tubeless. Best of all, this additional thought, care and attention to detail costs almost nothing over lesser cores while saving you pain and suffering over the coming years.
