Rodio's driver is designed to combine heterogeneous metals with the center position of the face and the center of gravity position to the maximum point with CT values, preventing the maximum distance and strike blur from reducing the distance. The compact driver, which shortens the center of gravity distance and depth and ensures outstanding operability that cannot be obtained with a large head, is excellent lye with golfers who catch the ball by turning face. It is easy to match the center of gravity position with the other count. Deep face and Mid face, changing the center of gravity position and moment of inertia around the axis. Deep back with short center of gravity distance and shallow depth is more operability, and the midback aims to achieve both stability and operability by suppressing head turns. Rodio is also a feature of rodio's ability to fine-tune by changing hozels and weight parts.
