From golf clubs currently on the market, among the 14 shafts in a club set, the longest and lightest driver shaft is soft, and the shortest wedge shaft is heavy and hard.
This, each golfer unconsciously distinguishes when swinging the club. And at that time of the swing, we observe that the club head speed for the driver becomes the
fastest and for the wedge club the slowest.
“Flex Consistency” is a concept born from the idea of being able to swing clubs more easily and comfortably (without much variation in speed), instead of the situation
with current standard clubs where the head speed gradually decreases as the shaft hardness increases.
By applying this concept to each of the 14 shafts in a club set, IMIDE AND SUNS is proposing “14 Complete Collection.”
