QUANTUM X PRO – The new reference – POP (PERFORMANCE ON POINT) Improved speed and ratio “rotation/ball trajectory” –> the ball trajectory is better and easier to control. A new, harder sponge confers more power and energy to your strokes. The rubber surface is dynamic and adhering. These features are the main characteristics of Quantum X Pro. POP (PERFORMANCE ON POINT) – This technology allows a better combination of power and rotation. The focus is not only to have a perfectly suited product combining the best playing characteristics, but, also and mainly to be able to achieve and unify extreme and maximum values in terms of rotation and speed. Many training hours are necessary to achieve this potential. This makes the task hard – not only for you but also for your opponents.
