A little bit of extra hardness can make all the difference. The DONIC BLUEGRIP S1 is the proof. The new addition to the BLUEGRIP table tennis rubber series is slightly harder than the BLUEGRIP S2, but significantly softer than the C1 and C2 versions. Thus, the BLUEGRIP S1 represents the missing element in the product range of this successful table tennis rubber series - the model for stronger professional players for whom the S2 is a little bit too soft, but who do not want to be without the touch and the pleasure of rotation of a real BLUEGRIP. The S1 has all the qualities of a real DONIC BLUEGRIP: the characteristic sticky-elastic surface, the dynamic sponge that provides the corresponding catapult effect, and the balanced ratio of speed and control that brings real playing pleasure. Simply DONIC BLUEGRIP.Technology: Professional table tennis rubber with dynamic medium hard, medium pored sponge and sticky top sheet.Characteristics: Extremely grippy and dynamic, allows precise strokesRecommended for: Offensive table tennis players who strive for perfect coordination of spin and speed.
