Introducing Progress BB4 Utility.
The leading technology accumulated through drivers and fairway woods has been incorporated into the utility more powerfully and more precisely.
The structure made of ultra-thin Ti-8-1-1 titanium with high trajectory during guard bulges the crown to its maximum value at the moment of impact and accumulates strength.
At this time, it meets the energy of the bellows sole, the core technology of Progress, and explosive power is transmitted to the ball, maximizing the initial speed.
In addition, the tungsten steel used in the sole has a deeper and lower center of gravity to maximize the hit rate of the shot.
The thickness of the material near the face of the crown is designed to be ultra-thin. The power of the crown that swells at the moment of impact and the compression power of the bellows sole increase the initial speed of the ball.
By designing a thickness of 13.mm-2.4mm from the face periphery to the center, the rebound coefficient is realized up to the maximum of the USGA-approved coefficient.
Ti-8-1-1-1 titanium of high trajectory is used from the face to the crown, and high specific gravity tungsten steel is used for the sole part, and materials of different specific gravity are joined by a brazing method. It is designed to be able to hit the ball quickly and easily with a deep and low center of gravity as well as fast initial speed by titanium.
