Our classic IV-L and IV-S versions are now available with the newly developed SGS (Sponge Grip Technology) comfort grip technology. When we employed IV-L SGS, we preserved the unique and well-chosen Ayous layers of the blade in their original form. Our research and testing, often carried out on professional players, resulted in a newly developed racket form that was customized to the grip shape, extending the "control - acceleration" interval. The enhanced grip mechanism gives your hand the necessary impulse.
