This anti-topspin disruptive rubber impresses with its insensitivity to rotation and the pronounced braking effect, which results in unsurpassable ball control. ELLEN DEF is the ideal rubber for classic defenders, as the soft sponge also gives players who are sensitive to topspin optimal control. ELLEN OFF, on the other hand, is suitable with the 10° harder sponge, ideal for varied active material play at the table.
