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.
