In 2006, an ambitious group of tour level tennis players got together and formed Genesis. With Genesis, these players want to revolutionize the game of tennis; creating products which help players compete better. Genesis spent three years researching tennis string. They tested and studied string composition, and finally, in 2009, they entered the market with the Black Magic string and Spin X string, two exciting polyester strings. Genesis puts all of their string through rigorous testing to bring tennis players of all levels the very best.
