It is made with Mandarin rubber with a 1.5 mm sponge, and equipped with Ergo Grip technology for better power transmission. 

According to the latest guidelines of the ITTF (International Table Tennis Federation), it is not necessary for the second side of the racket to have exclusively red rubber, but it can also have pink, purple, green, and blue, as long as the first side has black. Thus, the G30 racket is approved by the ITTF, giving you the opportunity to add more color to your game.
