Durable fibre for the right hardness of the tennis racket. Reduces vibrations, absorbs vibrations and additionally increases the stability of the grommet. Influences greater ball control and significantly improves racket performance and enhances racket efficiency.

Special holes located in the frame of the racquet are designed to enlarge the place where the ball can be hit with the greatest precision and power. Thanks to them, the so-called ‘sweet spot’ - the ideal place to hit the ball - becomes larger, allowing more power to be generated. These enlarged holes allow the racquet a greater range of movement of 56 degrees compared to the use of standard grommets.
