Pulsar compound and our Race Casing making the fastest road tire in the size.

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. \u003cbr\u003e\u003cbr\u003eFor optimizing around modern 25mm internal width 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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003ciframe width=\"1024\" height=\"576\" src=\"https:\/\/www.youtube.com\/embed\/iWI6G5oydY0\" title=\"Introducing PROTOCOL: SILCA's New Road \u0026amp; Gravel Race Tires\"\u003e\u003c\/iframe\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eRCR Architecture\u003c\/h3\u003e\n\u003cdiv class=\"rte-setting text-spacing\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eA volume-centric approach that prioritizes width and speed without adding useless bulk, built around lower pressures associated with modern ride rims.
