The figure above shows the correlation between shaft length and club head speed. The stiffness of conventional shafts is such that long shafts with high club head speed have the least stiffness (softest), whereas the shortest shafts have the most stiffness. It takes considerable athletic prowess and touch to swing both long, soft shafts through a large arc and short, stiff shafts through a small arc shaft with the same timing to achieve perfect impact. When playing a round of golf, many playerers will find it difficult to hit the second shot with the same timing after hitting your tee shot. Seven Dreamers’ flex consistency (FC) concept is aimed at ensuring consistent flex and swing comfort so as to enable the ball to be struck with the same timing irrespective of the length of the club.
Based on our flex consistency concept, we offer our FC Concept Series of shafts as a complete set of woods, irons and putter shafts designed for weight and flex consistency. The specifications table below presents our FC Concept Series lineup of full 14-shaft sets consisting of a combination of FC Concept iron sets with weight and flex consistency, together with wood and putter shafts.
