Fi'zi:k Antares R1 Carbon Braided Saddle. When every gram counts, the Fi'zi:k Antares R1 Carbon Braided Saddle shines so brightly. Its carbon braided rails and double carbon shell combine for superb strength, support and absolute minimal weight just 155 grams for the saddle. The Antares is made for riders who have average flexibility what Fi'zi:k considers a Chameleon in their Spine Concept fit system, but still like to move around on the saddle. It's a long, thinner saddle that helps you get into different positions depending on how you're riding, and the long, thin nose helps eliminate leg chafing the Wing Flex shell flexes downward where the inner thigh contacts the saddle, allowing more efficient pedaling and full range of motion.
