RCG-4 is the choice for the muddy days and the roughest of courses.

This intentional spacing prevents dirt and sticky loam from packing together and caking the tire. In sloppy conditions where other tires might clog and lose traction, the RCG-4 actively flings mud away, ensuring reliable bite and uninterrupted momentum. \u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv id=\"shopify-section-template--28635041726835__rich_text_fJDX39\" class=\"shopify-section index-section\"\u003e\n\u003cdiv class=\"text-left page-width\"\u003e\n\u003cdiv class=\"theme-block\"\u003e\n\u003ch2 class=\"rt-heading rt-heading--heading_FT7Lqw\"\u003e\u003cspan class=\"rt-heading__inner\"\u003eThe Protocol RCG-4 Gravel Tire\u003c\/span\u003e\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"shopify-section-template--28635041726835__1632425657d8b0ca36\" class=\"shopify-section index-section\"\u003e\n\u003cdiv class=\"page-width\"\u003e\n\u003cdiv class=\"grid grid--uniform grid--flush-bottom\"\u003e\n\u003cdiv class=\"grid__item medium-up--one-third text-center aos-init aos-animate\"\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"image-wrap text-spacing\"\u003e\u003cimg loading=\"lazy\" class=\"lazyautosizes lazyloaded\" alt=\"\" sizes=\"459px\" srcset=\"\/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_180x.webp?v=1787169289 180w, \/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_360x.webp?v=1787169289 360w, \/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_540x.webp?v=1787169289 540w, \/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_720x.webp?v=1787169289 720w, \/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_900x.webp?v=1787169289 900w, \/\/silca.cc\/cdn\/shop\/files\/DSC07951-preview_1080x.webp?v=1787169289 1080w\" width=\"570\" height=\"380\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eRCG-4 Architecture\u003c\/h3\u003e\n\u003cdiv class=\"rte-setting text-spacing\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eAn aggressive, wide-spaced knob profile that uses fewer but significantly larger lugs than the RCG-3.
