This rubber has what it takes to become a classic! Its very spinny, hard surface and the flexible medium sponge build up the core of this rubber. Excellent spin, control and pleasant speed are the results, when surface and sponge are interacting with each other. Every player type can take advantage of these characteristics – no matter if you prefer a passive playing style or powerful offensive strokes. andro Shifter’s unique advantage is the possibility for you to chose between two different ways to assemble the rubber: 0° for more speed, 90° for more spin and control. The sum of these characteristics make andro Shifter a real star among all-round rubbers!
