The Rasanter R42 has undergone the most intensive and groundbreaking development ever attempted with a German rubber. The goal was to develop a future-oriented rubber technology, which allows all ambitious and technically skilled players to compensate for the physical disadvantages of the 40 + ball as best as possible. The rubber surface of the RASANTER compensates for the rotational disadvantages of the 40 + ball, while the ultra-thick sponge increases the catapult effect and compensates for the lower speed of the cell free ball. This rubber is for Advanced to High level players. The medium 42? sponge stays soft enough for spins, while adding in a fair amount of speed.
