Our classical IV-L and IV-S are now also available with a newly developed comfort
grip system, the so-called SGS (Sponge-grip-system). With IV-L SGS we did not
make any changes to the classical composition of the blade?s unique and especially
selected Ayous layers. Our researches and tests commonly developed with world
class players resulted in a newly developed racket shape adapted to the grip shape,
making the interval ?control ? acceleration? even bigger. The new grip system gives
the necessary impulse to your hand.
