PRGR's unique β titanium U CUP face^* made of cold-rolled beta titanium DAT55G with a low-temperature bending process.
The low elasticity characteristics of β titanium DAT55G are utilized in a cup face design
to achieve large deflection even in a shallow head.

Thin-walled peripheral portions and a specially designed face
with greater deflection pursue high repulsion at the limit of durability.
Face deflects wide and large = high repulsion and large area.

The center of gravity, which is the highest repulsion point, is placed closer to the FACE center
to improve the actual hitting point repulsion. (Compared to the previous model)

The lightest weight in SUPER egg's history, and can be swung through faster.

While reducing the weight of the head, a deeper center of gravity and a larger center of gravity angle than the previous model were achieved.
Gently rise and grab.

It accelerates with a large amount of bending at the end of the hand.
Lightweight design, yet taut and speedy swing through.
