The brakeless front profile works as front or rear rim on modern disc-brake setups, eliminating weight penalties from brake tracks. At 284g, it offers exceptional lightweight performance while maintaining the stiffness and durability demanded by advanced BMX racers. Tubeless-ready construction enables modern lightweight tire setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3K Toray Carbon Weave Construction\u003c\/strong\u003e – Three-directional carbon fiber weave provides superior strength and stiffness-to-weight ratio compared to single-directional or alloy construction;

Spoke tension should be maintained at or below 115 KGF to prevent rim stress. Check wheel trueness before each race. Do not exceed 110 PSI tire pressure. Store and transport rim carefully to avoid impact damage. Carbon is susceptible to cracking from direct impacts; inspect regularly for damage. Front and rear versatility allows wheel swaps between positions if one requires inspection or repair.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-xs-12 col-sm-4\"\u003e\u003ccenter\u003e\u003cimg alt=\"\" height=\"292\" src=\"https:\/\/www.brgstore.com\/img\/cms\/XLCRIMS\/carbon451front.jpg\" width=\"207\"\u003e\u003c\/center\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-sm-8\"\u003e\n\u003cp\u003e\u003cstrong\u003eEXCESS XLS 451x21MM RIM SPECIFICATIONS\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eERD: 20\": \u003c\/span\u003e\u003cspan lang=\"en-us\"\u003e423.4mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eHeight: 23.3mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eInternal Rim Width: 16mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eExternal Rim Width: 22mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSpoke tension recommended \u0026lt;115KGF\u003c\/span\u003e\u003cbr\u003e\u003c!--115kgf--\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\" style=\"margin-bottom: 10px;\"\u003e\n\u003cdiv class=\"col-xs-12 col-sm-1\"\u003e\u003ccenter\u003e\u003cimg src=\"https:\/\/www.brgstore.com\/img\/cms\/ICONES%20JANTES\/tubelessready.jpg\" alt=\"\" width=\"50\" height=\"50\"\u003e\u003c\/center\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-sm-11\"\u003e\n\u003cp\u003e\u003cstrong\u003eTubeless Ready System\u003c\/strong\u003e - Our rims feature a Bead Lock System, needed for the rim to be Tubeless Ready.
