R47 Your profile is spin driven. Offensive topspin play at higher speed is your strategy. As a high level player you will take full advantage of the 47° sponge hardness for extra power and speed in your topspin play. Now You are equipped to perform topspins with a precise curved trajectory and to be creative in the semi distance play as well. Whats So Special About These New Rubbers? RASANTER is the most elaborate and complex rubber development ever undertaken in Germany. The goal was to develop a future-oriented rubber technology that allows all ambitious and technically skilled players to overcome the physical disadvantages of the 40+ ball. RASANTERs topsheet compensates for the rotational disadvantages of the 40+ ball, while the denser, ultra-thick sponge increases the catapult effect and compensates for the lower speed of the cell free ball. R asant means fast in German. Rasanter , of course, means faster . So that gives you a hint of what these new rubbers promise. But the performance advantage goes far beyond just being faster. Lets explore this new technology in depth. What problem are these rubbers trying to solve? Its been almost 3 years since the changeover to the 40+ poly balls. These new balls are now the standard ball used in all sanctioned tournaments. Compared to the celluloid 40 ball that preceded it, the 40+ ball is about 0.5 mm larger in diameter on average. In addition, the poly material is slicker and smoother than celluloid. Combined, these two characteristics result in a loss of spin and speed when identical force is applied to a 40+ poly ball compared to the celluloid 40 ball. Ever since the switchover to poly balls, table tennis manufacturers have been trying to make up for that loss. Andro has now done so with the introduction of their Rasanter series. But What Exactly Makes These New Rubbers So Much Better? First, lets take a look at the topsheet. Andro engineers have significantly thinned down the topsheet to only 1.7 mm thick
