Designed for competitive \u003cstrong\u003eBMX racing\u003c\/strong\u003e, this premium rear rim delivers maximum pedaling stiffness, rapid acceleration, and precise power transfer under race conditions.\u003c\/p\u003e\n\u003cp\u003eDeveloped with a full load-path engineering approach, the Hex Lab rim optimizes force transfer from pedals through the drivetrain into the rear wheel. This results in improved efficiency, reduced latency, and stronger forward drive on modern \u003cstrong\u003eBMX track bike\u003c\/strong\u003e setups. When paired with other Oversized components, it creates a highly responsive and unified stiffness system for maximum race performance.\u003c\/p\u003e\n\u003cp\u003eThe vacuum-molded ultra high modulus carbon structure ensures exceptional rigidity while maintaining a lightweight profile. The symmetrical dihedral angle stabilizers and sculpted spoke beds enhance structural integrity, allowing the rim to deliver the stiffness of a wider profile without unnecessary material increase.\u003c\/p\u003e\n\u003cp\u003eTubeless-ready compatibility and broad tire range support make this rim highly versatile across different BMX race conditions, while maintaining consistent performance and control.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eElite \u003cstrong\u003ecarbon rear rim\u003c\/strong\u003e for BMX racing performance\u003c\/li\u003e\n\u003cli\u003eOversized Technology for maximum system stiffness\u003c\/li\u003e\n\u003cli\u003eUltra High Modulus Carbon Fiber construction for superior rigidity\u003c\/li\u003e\n\u003cli\u003eOptimized load-path design for efficient power transfer\u003c\/li\u003e\n\u003cli\u003eSymmetrical dihedral angle stabilizers for enhanced stability\u003c\/li\u003e\n\u003cli\u003eSculpted spoke beds for improved strength and durability\u003c\/li\u003e\n\u003cli\u003eTubeless-ready and tube-compatible configuration\u003c\/li\u003e\n\u003cli\u003eDesigned for high-performance \u003cstrong\u003eBMX race bike\u003c\/strong\u003e builds\u003c\/li\u003e\n\u003cli\u003eOptimized for modern \u003cstrong\u003eBMX track bike\u003c\/strong\u003e responsiveness\u003c\/li\u003e\n\u003cli\u003eMatte black finish with chrome foil-stamped logos\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 20” (ISO 451)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal width:\u003c\/strong\u003e 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal width:\u003c\/strong\u003e 15.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eERD:\u003c\/strong\u003e 427 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole drilling:\u003c\/strong\u003e 28H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Ultra High Modulus Carbon Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess:\u003c\/strong\u003e Vacuum molded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve type:\u003c\/strong\u003e Presta\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 299 g (±10%)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Tubeless-ready (disc use)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOX","offers":[{"title":"20\" X 1 1\/8\" - 1 3\/8\"","offer_id":57417312469376,"sku":"BXRM21C20118RBK","price":399.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/1905\/0112\/files\/0009946_bxrm21c20118rbk_1_09b61cdf-2436-4786-917d-e79c60328781.webp?v=1771501758","url":"https:\/\/race2podium.com\/products\/box-hex-lab-carbon-rim-disc-rear-28h","provider":"Race2Podium","version":"1.0","type":"link"}
