Designed from the ground up to meet the modern demands of the discipline, these wheels combine \u003cstrong\u003eaerodynamic efficiency\u003c\/strong\u003e, impact absorption capability and light weight in a single solution. The NACA aerodynamic profile ensures stable airflow while reducing turbulence, while the wider internal channel allows a seamless transition between rim and tyre. Every structural aspect has been validated in the wind tunnel using rigorous methodologies, ensuring measurable performance in real race conditions.\u003c\/p\u003e\n\u003ch3\u003eCertified and Tested Aerodynamic Advantages\u003c\/h3\u003e\n\u003cp\u003eThe aerodynamic drag of the Graff RD is reduced by \u003cstrong\u003e6.92% at 30 km\/h\u003c\/strong\u003e and \u003cstrong\u003e5.94% at 40 km\/h\u003c\/strong\u003e compared with the previous generation when fitted with 47 mm tyres, the configuration with the highest potential. With 50 mm tyres, they still deliver significant advantages, recording reductions of 2.73% and 3.92% at the same speeds. Wind tunnel tests covered yaw angles from -20° to +20°, variable speeds and different tyre sections, confirming the aerodynamic superiority of the Graff RD design in every tested configuration. This scientific approach guarantees reliable performance both on competitive courses and in \u003cstrong\u003evaried gravel\u003c\/strong\u003e conditions.\u003c\/p\u003e\n\u003ch3\u003eTechnology and Design for the Modern Gravel\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eGraff RD tubeless wheels\u003c\/strong\u003e respond to the increasing speeds and technical difficulty that define contemporary gravel. The rim geometry has been completely reimagined to optimise aerodynamic performance without compromising the discipline’s impact absorption capability. \u003cstrong\u003eTubeless\u003c\/strong\u003e compatibility allows lower tyre pressures, improving grip and comfort on uneven surfaces. The increased external width creates a stable base for 47 to 50 mm tyres, offering versatility in tread selection. This combination of \u003cstrong\u003eaerodynamic innovation\u003c\/strong\u003e, structural strength and practical usability represents the current standard for those aiming for high performance in competitive gravel.\u003c\/p\u003e\n\u003ch3\u003eTechnical Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNACA aerodynamic profile to reduce turbulence.\u003c\/li\u003e\n\u003cli\u003eWider internal channel with optimised rim-to-tyre transition.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eTubeless\u003c\/strong\u003e compatibility for lower pressures and improved grip.\u003c\/li\u003e\n\u003cli\u003eAerodynamic drag reduced by 5.94-6.92% with 47 mm tyres at 40 km\/h.\u003c\/li\u003e\n\u003cli\u003eWind tunnel tested with yaw angles from -20° to +20°.\u003c\/li\u003e\n\u003cli\u003eSupports 47-50 mm tyres for versatile use.\u003c\/li\u003e\n\u003cli\u003eDeveloped for UCI Gravel World Series competitions.\u003c\/li\u003e\n\u003cli\u003eLow weight while maintaining torsional and lateral stiffness.\u003c\/li\u003e\n\u003cli\u003eMatte black finish resistant to wear and UV rays.\u003c\/li\u003e\n\u003cli\u003eDisc brake compatibility for greater braking reliability.\u003c\/li\u003e\n\u003cli\u003eASTM: 2\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHubs: AL 7075 T6 CNC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpokes: Vonoa® Carbon Aero Profile 4x1 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNipples: AL 7075 T6 \/ Black\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight (g): 1,455 g +\/- 3% (Tubeless Ready \u0026amp; Valve included)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLacing: 24 - 24 \/ Crossed\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpacing (mm): 100 - 142\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBearings: CeramicSpeed® Alpha\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDrive: RES 30 Rapid Engagement System\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatibility: SH MicroSpline, Shimano® HG, SRAM® XDR, Campagnolo® N3W\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum bike + rider load (kg): 108 kg\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRim height (mm): F 52 - R 52\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBrake system: Disc Center Lock\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncluded accessories: Wheel bag \/ Instructions \/ RD center lock disc brake lockring\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRim material: T700 \/ T800 carbon fibre in matte finish\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFreehub body: AL 7075 T6 + Titanium\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRim size: 622X30 TC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTyre size: 47 mm ÷ 65 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTyre type: Tubeless\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFront axle diameter (mm): 12\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRear axle diameter (mm): 12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Miche","offers":[{"title":"XDR \/ Black","offer_id":54974552539482,"sku":"WHGRD0B0UX000","price":2250.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/flex-section.jpg?v=1791872212","url":"https:\/\/maisoncalyx.shop\/en\/products\/ruote-miche-graff-rd-tubeless-nero","provider":"All4cycling ","version":"1.0","type":"link"}
