Tibhar's classic IV-L blade is now available with a newly developed comfort grip system, SGS (Sponge-grip-system). With IV-L SGS, Tibhar did not make any changes to the classic composition of the blade's unique and specially selected Ayous layers. Our research and tests, developed in cooperation with world class players, resulted in a newly developed racket shape adapted to the grip shape, increasing both control and acceleration. The new grip system gives the player excellent feel and feedback.
