Our tour professional version of Internal Mechanic Boost (IMB) makes you control the magnitude of spin energy easier and better. Developed by and made for tour professionals, Sigma II Europe also shapes the ball trajectory easier than any other rubbers. Professional players know the well-controlled short balls and the accurate ball path increase the real winning probability. You can also charge far more energy on the spin with IMB technology.
As a result, the ball winds up quicker and aggressively lower at the opponent's court while it can start comfortably higher.
