A technology used in the manufacture of tennis racquets, which is characterised by the use of larger guides, resulting in more efficient string action. This results in a stronger impact and better ball feel.

Wilson brand technology using basalt, a natural volcanic rock. Used in tennis racquets, it provides vibration dampening, improved motion control and protection for the user's joints. The resulting basalt fibres are braided with (K)arophite Black material, resulting in an advanced composite. In addition, the material has greater thermal stability and durability.
