By adopting the proven rim profiles of the Artech series (without the Aeroscales) the R4.A delivers best in benchmark-tested aerodynamic performance. With steel spokes and a total weight of just 1398 grams, it is the ultimate all-round, climbing and even gravel wheelset fitting wider tires and built to excel both in the heat of competition and in the demands of daily training.
Beyond its low weight and aerodynamic advantage, the R4 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.
