New material cup face x new core system structure Aim for maximum distance with high quality ball contact



High initial velocity across the entire face. Equipped with a quattro cup face with a geometric pattern that extends to the back.
The cup face is made of a new titanium zirconium alloy (RZR446 titanium) that Romaro developed in collaboration with a materials manufacturer. Its light, thin, and strong properties, as well as its large and flexible bending, have resulted in a wide-area repulsion face with a quattro design that produces excess weight through further weight reduction, leading to high initial velocity and increased distance.
Square impact for powerful and straight shots. New core system structure aims for maximum individual distance.
The new "Core System" structure aims for "high quality ball contact" that allows the face and body to hold the ball firmly without being overwhelmed by the ball at the moment of impact, and launch it powerfully in the direction of the target. The thin and lightweight face and excess weight of the crown are concentrated in the core system, realizing a low and deep center of gravity setting that is easy to grip despite the large head. The cup face and crown flex effect, along with the appropriate spin for a high launch, aim for maximum individual distance.
