Arione R5 is a comfortable, ride-compliant saddle with a flat profile and streamlined shape. As the longest saddle in our lineup, Arione allows for considerable fore-to-aft movement, letting riders find their ideal power and comfort centers while reducing pressure in the most aerodynamic riding positions. Built with our low-profile Type-1 foam padding, Vento Arione R5 provides lasting support--complete with a carbon-reinforced nylon shell to save weight and ultra-durable S-Alloy rail.
