Classique Pro presents a special pips design which provides a totally different feeling for chop defence. The "Nanos" technology enables the rubber to create amazing backspin strokes with excellent control, and also adequate speed to counter with disturbing attacking balls. These effects are supplied by "GREEN" and "negatron" technologies. "GREEN" technology used on AIR sponges offers a soft feeling and gives enormous power to the rubber with an excellent bounce and a strong rebound. "Negatron" is the latest technology for non-elastic requirements and most players actually prefer the sponge like this. This technology offers the highest control and excellent ball feeling.
