R4.A V2 45mm Allroad Wheelset

Race - Alload wheels | Developed for paved roads when riding wider tyres, offering best in class aerodynamics, at a race ready weight, and are built to last.Race-bred performance derived from the ArtechDerived from the award-winning Artech series and built from the same engineering DNA, the R-Series brings revolutionary technology to a broader stage, delivering best in class aerodynamics, at a race ready weight, and durability designed to last.By adopting the proven rim profiles of the Artech series (without making use of the Aeroscales), the new R-Series guarantees optimal aerodynamic performance.Beyond its low weight and aerodynamic advantage, the R4.A combines exceptional lateral stiffness with uncompromising durability. Its 25 mm internal width hooked rim is aerodynamically optimized for 30 mm clincher and tubeless tires, offering the perfect balance of rolling resistance, efficiency, and comfort. Meanwhile, the mechanical labyrinth system protects against dirt ingress, ensuring long-term reliability and consistent performance.AEA: Algorithm Enhanced AerodynamicsLocal Reinforcement carbon lay-upTopology OptimizedScope Tubeless Hooked SystemHubs: Scope R-Series Diamond Ratchet SLSpokes: Sapim CX-Ray 21 front, 24 rearSKF Bearings45mm Rim Depth25mm Internal width33.7mm External widthWeight: 1398gNo rider weight limitThree year warrantyLifetime crash replacementTubeless valves & tape pre-installed
