Taking the shape of Fi'zi:k's premium Arione Donna Saddle, the Fi'zi:k Arione Donna Manganese Women's Saddle is shorter and wider at the rear portion for anatomically contoured, women's specific comfort. Its medium firm, high density foam padding features a pressure relief channel through its running length for enhanced comfort over long distances. The carbon reinforced nylon shell delivers extra stiffness, with Wing Flex notches along the sides that flex downward where your inner thighs rest against the saddle. Ultimately, these notches not only enhance comfort on day long century rides and fast paced training spins alike, but they also promote full range of movement for added efficiency. Moreover, you'll find the saddle's manganese rails are corrosion resistant for long lasting use. And although they're a bit heavier than the K:ium alloy rails you'll find on the Arione Donna, the payoff lies in the Arione Donna Manganese's more affordable price.
