(President: Tadanobu Nagumo) will release the new concept driver "egg impact PX-01 (egg impact PX-01)" from the egg series, which breaks the common sense of "ease" and "distance," through PRGR Co., Ltd. (President: Masahiro Mori) from October 24th. There are three types depending on head speed: "M-37 (37m/s)", "M-40 (40m/s)", and "M-43 (43m/s)", and the price is 68,250 yen (65,000 yen excluding tax) per club. "egg impact PX-01" is a new concept driver developed with the aim of "improving the rate of contact at impact, and easily increasing distance and fairway keeping rate." By making the club length 43.5 inches, the contact rate has been improved, and by making the club head heavier at 206g, the energy efficiency at impact has been improved. In addition, the "egg impact PX-01" dedicated shaft is designed to flex throughout the shaft, with low tip stiffness, designed to accelerate the head. It is a user-friendly club that allows you to swing with confidence, and the increased contact rate increases the initial ball speed, resulting in increased distance. The "egg" series is a club series based on the concepts of "not being bound by preconceived notions," "breaking the shell of an egg," and "prioritizing performance (distance, ease of use)." It is supported by a wide range of golfers because it is easy to hit and provides distance, and already has a lineup of spoons, fairway woods (#5, 7, 9), and irons.
