Constructed from 3K carbon weave with a brake track surface and angled spoke holes, this rim accommodates 20x1-1\/8\" or 20x1-3\/8\" tires on the 451mm bead diameter standard. The carbon construction delivers high strength and stiffness at reduced weight compared to aluminum, optimized for mini\/cruiser applications.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3K carbon fiber weave\u003c\/strong\u003e – Carbon construction provides high stiffness-to-weight ratio and vibration damping characteristics compared to aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake track surface\u003c\/strong\u003e – Designated braking surface compatible with caliper, U-brake, or V-brake systems (verify carbon-specific brake pad compatibility)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngled nipple holes\u003c\/strong\u003e – Spoke holes drilled at an angle for more direct spoke alignment, improving spoke tension consistency and wheel stiffness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-profile aero design\u003c\/strong\u003e – 23.3mm rim height balances aerodynamics with structural strength for mini\/cruiser use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubeless-ready bead lock system\u003c\/strong\u003e – Internal bead lock profile allows tubeless tire setup when used with tubeless valve, rim tape, and sealant (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e28-hole configuration\u003c\/strong\u003e – Lighter spoke count reduces overall wheel weight while maintaining adequate strength for mini\/cruiser riders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-gloss finish\u003c\/strong\u003e – Clear coating protects carbon weave and provides visual depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim size:\u003c\/strong\u003e 20\" (451mm bead diameter)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim width (external):\u003c\/strong\u003e 22mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim width (internal):\u003c\/strong\u003e 16mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim height:\u003c\/strong\u003e 23.3mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eERD (Effective Rim Diameter):\u003c\/strong\u003e 423.4mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 3K carbon fiber weave\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpoke hole count:\u003c\/strong\u003e 28 holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpoke hole type:\u003c\/strong\u003e Angled nipple holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve type:\u003c\/strong\u003e Presta\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e High-gloss clear coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 289g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended maximum spoke tension:\u003c\/strong\u003e \u0026lt;115 KGF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake compatibility:\u003c\/strong\u003e V-brake, U-brake, caliper brake (brake track surface—requires carbon-specific brake pads)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubeless compatible:\u003c\/strong\u003e Yes, with bead lock system (requires tubeless valve, rim tape, and sealant)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003eThis rim is designed for 20\" mini BMX and cruiser frames using rim brakes—most commonly as a rear wheel with V-brakes, though it also works with U-brakes or caliper brakes. The 451mm bead diameter is the standard for mini\/cruiser bikes, not the 406mm used on traditional BMX bikes—verify your frame and tire compatibility before ordering. The 28-hole drilling works with 28-spoke hubs in various lacing patterns. Note the 423.4mm ERD requires proper spoke length calculation—verify spoke length before ordering or building.\u003c\/p\u003e\n\u003cp\u003eBest suited for mini BMX and cruiser riders who use rim brakes and want the performance benefits of carbon fiber construction—reduced rotational weight, increased stiffness, and improved responsiveness. \u003cstrong\u003eCritical: Carbon rims with brake tracks require carbon-specific brake pads—standard rubber pads designed for aluminum will overheat the carbon and can cause catastrophic rim failure.\u003c\/strong\u003e Verify brake pad compatibility before use. The 22mm external width and 16mm internal width are optimized for the 1-1\/8\" to 1-3\/8\" tires typical of mini and cruiser bikes. The tubeless-ready design benefits riders looking to further reduce weight and gain puncture protection. Ideal for riders within typical mini bike weight limits who ride park, street, or cruising and prioritize performance. Carbon rims require careful handling during installation and maintenance—overtightening spokes or using incorrect brake pads can damage the rim. Not recommended for disc brake or brakeless setups—choose a brakeless surface version for those applications.\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\/carbon451rear.jpg\" width=\"202\"\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.
