The Arione is longer than any other saddle, flat from the tip to the end, and equipped with a narrow nose that allows for greater freedom of movement and the finding of the optimal power center. The shell of the Arione R3 is made from a composite glass-co-injected nylon shell for the best support with optimized stiffness while simultaneously reducing weight. The Wing Flex technology allows for flexibility where the thighs meet the saddle, and the Kium aluminum rails ensure low weight.
