Race Division — Feel the Formula Deva RD stems from a development journey built on thirty years of experience. It is our first wheel featuring Vonoa® carbon spokes, designed to exceed the highest standards of performance, efficiency and reliability. Developed according to the Miche Formula — an engineering protocol that integrates instrumented measurements, high-resolution CFD simulations, and dedicated wind tunnel sessions to validate every design choice. 4 preliminary designs, 28 CFD simulations by Groupama–FDJ Tech Centre 24 hours of wind tunnel testing across 3 sessions T700/T800/T1000 carbon structure, matte UD finish, 23 mm tubeless-ready internal width 62 mm differentiated profiles (front 62×31 mm, rear 62×30 mm) for optimal aerodynamic efficiency Vonoa® carbon spokes: 4×1 mm aero profile, 14+7 spoke configuration (21 total) CeramicSpeed® double-sealed ceramic bearings Technical Specifications ASTM: 1 Rim material: T700 – T800 – T1000 UD Carbon fibre, Matt finish Rim profile: F 62 – R 62 mm Rim dimension: 622 × 23 TC Tyre type: Tubeless Tyre dimension: 28 mm ÷ 38 mm Spokes: Vonoa® Carbon & titanium 4×1 Aero Profile Assembly: 21-21 Radial/Crossing Hubs: AL 7075 T6 CNC Bearings: CeramicSpeed® 2RS Braking system: Disc Center Lock O.L.D.: 100-142 mm Front/Rear axle: 12 mm Compatibility: Campagnolo® N3W, Shimano® HG, SRAM® XDR Weight: 1375 g (±3%) Max load (bike + user): 105 kg
