Ultrathin Power Spring Body Made
Possible by
RYOMA’s Proprietary
Material-Engineering and
Manufacturing Technologies

The body shell of the club head—comprising a spring
crown and a
spring sole—compresses and expands
like an elastic body (spring)
when the powerful inertial
energy generated by a stationary ball and
two
weights inside the head travels inward upon impact.
