Super Grommet technology incorporates Speedgrommet, figure 8 grommet shape for more string movement in all directions and less grommet/string friction, with V-Sponse material. This combination of shape and material gives a larger sweet spot, better control and more energy return to the ball.
Most tennis racquet have the pivot point of their string beds at the inside of the grommet. Strings in Volkl Tennis racquets using Speedgrommet technology pivot closer to the outside of the frame because the grommets are shaped like a figure 8 funnel. This increases dwell time, the amount of time the ball spends in the string bed thereby enhancing spin and control. In addition, the string bed has more energy to release for more power without requiring a bigger swing.
