SuperSpeed Golf SuperSpeed Golf C SuperSpeed Golf SuperSpeed C (1 club) This is a training tool with one club that applies the overspeed training theory. The "C" in SuperSpeed C stands for counterweight, and by distributing weight to the red line part of the grip end, it reduces the resistance when the club head is released near impact, maximizing swing speed. SuperSpeed C has a total weight equivalent to a standard driver, but it feels easier to swing due to the counterweight effect, maximizing the release speed of the swing near impact. This allows you to train for increased head speed while naturally acquiring the feeling of the head running. The rotational speed of a golf swing chains up from the ground to the hips, torso, and finally to the arms and hands, so golfers need to perform this chain of motion efficiently to maximize the speed of the club head at impact. ■ Length: 45.75 inches ■ Weight: 310g ■ Manufacturer's suggested retail price: ¥14,800 (tax included) Purchased new and only used 2-3 times at the driving range, so it's hardly been used.
