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.\u003cbr\u003e\u003c\/p\u003e","brand":"SILCA","offers":[{"title":"Default Title","offer_id":18005040324,"sku":"AM-VV-TUB-ASY-009","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0309\/9521\/products\/Valve-Cores-800x800.png?v=1673466326"},{"product_id":"ultimate-sealant-remover","title":"Ultimate Sealant Remover","description":"\u003cp class=\"p1\"\u003eWATER-BASED ‚ BIODEGRADABLE\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThis patented formula breaks down the molecular bond between the latex and the surface to which it has attached.

By leveraging this increased air volume to absorb impacts and reduce flat risks, we stripped away heavy, redundant puncture layers. This allows us to keep the tire lightweight, fast, and comfortable to offer riders the high-volume performance they have been asking for. \n\u003cbr\u003e\u003cbr\u003e\nFor optimizing around modern 25mm internal hookless rims, our 29mm wide tire is the sleekest option that fully complies with ETRTO standards. To eliminate the safety vulnerabilities typical of hookless setups, we integrated our Carbon BeadLock technology. Unlike standard Kevlar beads that stretch and \"creep\" over time, which increases blowoff risks; our rigid carbon fiber beads never stretch. From local criteriums to the punishing cobbles of Paris-Roubaix, Protocol RCR keeps you rolling fast and safe. ","brand":"SILCA","offers":[{"title":"700 x 29mm","offer_id":63060371472755,"sku":"AM-AC-074-ASY-0100","price":99.0,"currency_code":"USD","in_stock":true},{"title":"700 x 34mm","offer_id":63060371505523,"sku":"AM-AC-074-ASY-0200","price":99.0,"currency_code":"USD","in_stock":true},{"title":"700 x 38mm","offer_id":63060371538291,"sku":"AM-AC-074-ASY-0300","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0309\/9521\/files\/RCRSQUARESide.png?v=1786539599"},{"product_id":"protocol-32-rcg-3-gravel-tire","title":"Protocol 32\" RCG-3 Gravel Tire","description":"\u003cdiv class=\"OutlineElement Ltr SCXW256768455 BCX0\"\u003e\n\u003cp\u003eThe RCG-3 is the successful result of our mission to make the best gravel tire on the planet. Arriving at gravel tire development with a fresh perspective, we took the characteristics everyone loves about fast XC MTB tires and optimized them for modern gravel with ultra-fast road tire casing concepts. The RCG-3 delivers robust flat protection without sacrificing speed.
