With a total weight of just 1,302 g per pair, this wheel delivers a 159 g reduction compared with the previous model, significantly improving \u003cstrong\u003eclimbing response\u003c\/strong\u003e and acceleration. The carbon rim, subjected to more than 5.4 million aerodynamic simulations, delivers a 6% aerodynamic improvement, helping maintain high speeds in every racing condition. The \u003cstrong\u003eaerodynamic structure\u003c\/strong\u003e of the 50 mm profile perfectly balances lightness, stiffness, and efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction Technology and Optimal Stiffness\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003erear wheel\u003c\/strong\u003e design incorporates \u003cstrong\u003ecarbon spokes\u003c\/strong\u003e optimized to distribute load while keeping overall weight low. The 21-spoke per side lacing pattern, combined with mixed diameters, ensures \u003cstrong\u003esuperior stiffness\u003c\/strong\u003e for maximum power transfer during sprints and high-speed cornering. The rear wheel's DIRECT ENGAGEMENT system guarantees instant response to rider input, while the hooked tubeless rim with an internal width of 23 mm reduces rolling resistance and maintains stability with 28-30C tires. The \u003cstrong\u003ecup-and-cone system\u003c\/strong\u003e allows excellent maintenance and precise adjustment, extending wheel life under demanding race conditions.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility and Technical Specifications\u003c\/h3\u003e\n\n\u003cp\u003eThis \u003cstrong\u003erace wheel\u003c\/strong\u003e is designed to accommodate tire sizes from 28-622 up to 45-622 (700C), supporting both tubeless and clincher setups. The 23 mm internal rim width is optimized for modern tires, ensuring stable handling and reliability on tarmac. The wheel is compatible with \u003cstrong\u003eShimano Dura-Ace\u003c\/strong\u003e 12-speed hubs and requires tubeless rim tape. The 50 mm aerodynamic profile offers the best compromise between weight, aerodynamics, and torsional stiffness, making it the ideal choice for riders seeking \u003cstrong\u003ecompetition performance\u003c\/strong\u003e on the road.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear weight\u003c\/strong\u003e: 709 g\u003c\/li\u003e\n\u003cli\u003eRim height: 50 mm\u003c\/li\u003e\n\u003cli\u003eRim material: \u003cstrong\u003eCarbon\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eNumber of spokes: 21 (rear)\u003c\/li\u003e\n\u003cli\u003eInternal rim width: 23 mm\u003c\/li\u003e\n\u003cli\u003eTire type: Tubeless\u003c\/li\u003e\n\u003cli\u003eRecommended tires: 28-622 – 45-622\u003c\/li\u003e\n\u003cli\u003eWheel size: 622 x 23TC (700C)\u003c\/li\u003e\n\u003cli\u003eRim: hooked tubeless\u003c\/li\u003e\n\u003cli\u003eDrive system: DIRECT ENGAGEMENT\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Shimano","offers":[{"title":"Shimano 12-speed \/ Black","offer_id":54803124224346,"sku":"EWHR9370C50LREDB","price":1495.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/Ruota-dura-c50-psot.png?v=1789641506","url":"https:\/\/maisoncalyx.shop\/en\/products\/ruota-posteriore-shimano-dura-ace-wh-r9370-c50-tl-r-12-nero","provider":"All4cycling ","version":"1.0","type":"link"}
