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. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\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\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003eImportant: Never install tires with a tire lever.\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-block\"\u003e\u003cspan\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"product-block\"\u003e\n\u003cspan\u003eSPECS:\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-block\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e29, 34, 38mm options\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e290g in 29mm, 320g in 34mm, 350g in 38mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e120 TPI\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSealSkin Tread Protection\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFastest Pulsar compound\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWidth as measured on a 25mm rim after 24 hours\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDesigned for race conditions\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRCR Architecture\u003c\/p\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.
