JIGEN eRookII Driver

When the billiard ball hits the target ball, the movement energy shifts to the target ball at the time of impact, the movement of the hand ball stops, and the target ball starts to move.
In the case of golf, the point that the kinetic energy of the head is transferred to the ball is the same theory.
This time, Mr. Kobayashi, who is in charge of development, focused on the CT value. Generally, the higher the CT value, the stronger the repulsive force and the better the ball will fly. However, if the ball is released too quickly, the kinetic energy in the head and the angle will not be sufficiently transmitted to the ball, and the ball will move away from the head.
This eRook II driver reviews the internal structure of the head to generate efficient kinetic energy and properly transmits it to the ball to make a hit ball in good condition.

We have developed a structure in which the body is made of carbon and weights can be attached to the carbon material, and we are thoroughly reducing the weight and placing weights on the sole, and we are thoroughly regularly designing high trajectory and low spin.
The inner ribs are arranged on the theory that there is no wasted energy loss in the head because the head has no wasted sound by verifying the reverberation of the hitting sound and there is little reverberation.

The RK55z has a large amount of backspin, and the eRook II has an ultra-low spin. This head is recommended for those who have a large amount of backspin or who have a fast head speed and cause a loss. If the amount of backspin is small, it is difficult to increase the flight distance because the flight time cannot be earned.
