The ideal rubber for attacking players who previously used soft rubbers with speed glue. ACUDA S2 is a fast rubber with a medium soft large pored sponge. This produces fast speeds and has a uniquely loud sound. ACUDA S2 is well suited both for close to the table and away from the table game. It will give an advantage in topspin/topspin duels. This rubber is particularly enjoyable to play with because of its precise feel.
