Flexpoint racquets feature two precisely-engineered control holes in the racquet's head. This creates a new point of flex, which cups the ball and improves control without losing power. The patented HEAD Flexpoint technology breaks the rules of traditional racquet design by not making racquets stiffer, but by engineering them to flex in a new and revolutionary way.
With a conventional racquet, the ball strikes the racquet at 90 degrees, but due to the racquet flexing it leaves the racquet at a different angle. A Flexpoint racquet is designed to cup the ball by flexing at the Flexpoints. The cupping effect reduces the angle at which the ball leaves the strings and promotes more accurate hitting. Flexpoint technology increases the dwell time and ball pocketing due to its cupping effect which increases feel and provides a larger sweetspot.
Flexpoints are made up of two complimentary features and are located at the 3 and 9 o'clock positions on the racquet head. Each Flexpoint features an engineered dimple to create flexibility by reducing the beam width by a maximum of 25%. Each Flexpoint also features a hole in the center of the dimple which reduces sectional stiffness by 50%.
Developed by the California Institute of Technology (CalTech), LiquidMetal® alloy provides 29% more power than Titanium. Just as its name implies, LiquidMetal® alloy is different from conventional materials because of its liquid (or "amorphous") atomic structure. This means that LiquidMetal® alloy does not deform on impact, resulting in ultimate energy return.
Head places LiquidMetal® at four strategic areas of the racquet's head, integrated in the main layer of the frame's construction. This allows all of the energy from ball impact to be used for a power return - so what a player puts into his or her swing is exactly what they get out. The result is what Head calls Pure Energy. Perfect Power
Total Sweetspot Construction
Total Sweetspot Construction increases torsional stability in the racquet head and extends the sweetspot throughout the entire racquet head, resulting in ultimate control.
Intellifiber is a new fiber created from piezoelectric material. Extraordinarily different from conventional materials, this fiber (according to Head) transforms the mechanical energy from ball impact into an electrical response that stiffens the racquet for ultimate power. Intellifibers are integrated on both sides of the throat area. An electrical impulse actively changes the shape of the fibers - in less than a millisecond - at ball impact.
According to Head, in less than the first millisecond of ball impact, Intellifibers stiffen and reduce bending in the throat area for unmatched power in current racquet design. Unlike mechanical energy, electrical energy does not create vibrations. Therefore, 20% of the vibrations are immediately eliminated upon ball impact for optimum comfort.
The inner hard shell of TwinTube technology is made of pure graphite. The outer shell consists of soft, absorbing polyamide.
Increased ball acceleration combined with better, overall racquet feel.
