The BLUEGRIP was already a revolution in its V1 and R1 versions: The best of two worlds in one rubber! Now DONIC continues this development. With the BLUEGRIP C1 and C2, two versions of this series have been added that put everything else in the shade. The following also applies to these two: The DONIC BLUEGRIP has a sticky Chinese-style surface and a sponge with a powerful catapult effect and enormous dynamics, which is only known from rubbers from Germany and Japan. But this dynamic has now been significantly increased. With the 60° hard sponge of the C1 version, the ball describes an even stronger arc during topspin and gets even more speed, the C2 has a slightly softer sponge and also fine differences in the pimple geometry, which additionally support the softer feel.
