After seeing that the Hybrid K1 one was becoming very popular, Tibhar created the next version, the Hybrid K1 Plus. Like the K1, the K1 Plus is rubber by Tibhar for the Chinese playing style. Unlike the K1, the K1 Plus has a harder sponge, allowing you to hit the ball with greater strength and create greater speed without losing control. With this rubber, you will be assured stable flight curves which are difficult for your opponents to receive. The K1 Plus can be used for both offensive and defensive play. Boosters can be used to further improve the play characteristics of all K series rubbers.
