Rasanter R45, R48, C48, R53 and C53 rubbers are equipped with the sponge that has the same pore size as the previous Rasanter versions but with increased inner tension. This makes each cell a small compressor and gives the rubber greater power potential. C is for counter-spin. The pimples in the topsheet of Rasanter C rubbers are equipped with wider basement that neutralizes the incoming rotation and allows controlled counter-spins with aggressive trajectories. Due to the compression of that pimple base, the Rasanter C also makes it possible to improve the serve-return game considerably. The 48 degree version allows to bring the variation into the player's game. The rubber makes it easy to stay stable on the passive shots and short game.
