Ryoma GOLF

The only club head whose center of gravity aligns perfectly
with that of a ball at impact

Most conventional Fairways equipped with a head body made of stainless or maraging-steel make a sweet spot is higher than the center of gravity; it makes incapable of hitting a ball with the center of gravity. With conventional head, the face directs downward at impact. This is one of off-center hits that makes energy off and increase backspin rate.
A RYOMA F fairway wood incorporates RYOMA’s proprietary DSI technology; an innovative head structure made of ultrathin, high-strength hot-forged titanium. The total 125 g weight made the center of gravity aligns perfectly with that of a ball at impact. RYOMA’s deep face head gives the head a deep and low center of gravity and maximizes the inertial moment. This powerful inertial moment imparts substantial energy to a ball upon impact, which, as a result, takes a straight flight over a longer distance.

1Higher Initial VelocityBall’s initial velocity boosted by 2.0 m/s

The power-spring body and the Multi-Beam Cup Face made of an ultra-thin titanium alloy combine to provide a large sweet area to impart a consistently high initial velocity to the ball regardless of the point of impact on the face. Thanks to RYOMA’s proprietary DSI technology that makes the most of the rebounding characteristic of a ball, it is possible to hit a ball with an initial velocity of up to 2.0 m/s higher than conventional fairways.

RYOMA F5 has actualized the high initial velocity and low-spin ball whose flight distances stretches
equivalently to the F3 of other companies.

  • 2Reduced BackspinBall’ s backspin rate down
    by 850 rpm*

    The combination of an under-press crown, a 60 g low-spin unit, and a 65 g anti-roll power booster lowers the center of gravity of the club head. And the spring body transfers maximum energy to the ball at impact. This innovative head design brings the ball’s backspin rate down by up to 850 rpm. As a result, the ball is given a higher initial velocity and a higher trajectory and takes a straight flight to the green, even in crosswind.

    Severity of Hooks or Slices
    Lessened by 50% or More

    When a ball is hit with the lower part of the club face, the propulsion force generated by the Low-Spin Unit and the Anti-Roll Power Booster inside the club head prevents the head from angling upward. When a ball is hit with the upper part of the face, the Under-Press Crown prevents the ball from ballooning and helps it maintain a high initial velocity. On a horizontally off-center hit, compression applied to the Under-Press Crown works to reduce the amount of sidespin imparted to the ball. The player can, therefore, have excellent control of direction and improve his or her score on the course.

DSI technology suppresses the rotation of the head for any kind of off-centre hits; it enables stable
distance and directionality
