All fi’zi:k saddles are designed with and for the world’s very best pro racers, ensuring enhanced comfort and ultimate performance. Fizik's extensive three-year research project shows that there is demand for a collection of wider-fitment saddles to complete the selection for optimum fit for every rider. The Antares R3 K:ium benefits from improved weight distribution and a host of fi'zi:k technologies including a strong, supportive Carbon Kevlar thermoplastic composite shell and alloy K:ium rail, and Wing Flex which enables flexibility where your thighs meet the saddle.
