What does shaft flex mean?
Shaft flex most commonly references the ability of a golf shaft to bend as forces are applied to it during the swing. Forces can be applied in a number of ways, and is typically measured by the swing speed, or the characteristics of your golf swing. When a shaft is accelerated in the golf swing it causes most shafts to flex, twist, and droop. When the club head droops throughout a golfer’s swing, it will cause the player to misalign the club face as it returns to impact. In golf, to maximize your shot making and performance, the face of the club must be square at impact.
