Q & A
New RIBCOR design localizes club face flexibility in the hitting area to transfer more energy to the ball for more distance and forgiveness. It also stiffens the perimeter of the club head for a more rigid club, enhancing sound and feel. RIBCOR creates a tighter dispersion by limiting the flexibility of the toe area.
Weighting is optimized in the heel and toe of the club head to significantly increase MOI over the 2017 M2 irons.
The Speed Pocket and ultra-thin leading edge work together to increase speed on shots it low on the club face. Face slots are also included to protect ball speed.
A fluted hosel and 360° undercut cavity distributes mass low in the club head for greater launch, distance, and consistency. Plus, M4 recues replace the longer irons for improved forgiveness and distance for those longer shots toward the green.
