You can order the Yonex Exbolt 63 Black here. This is the first string of the new series of badminton strings, the EXBOLT. These new strings are made from a new material, namely FORGED FIBER. This new and innovative material combines durability, thin gauge and fast repulsion to make the game of badminton even more dynamic. Thin strings usually already had a quick repulsion, but this was often at the expense of durability. By using firmer fibers in the production of the EXBOLT strings, durability has also been improved. The Yonex Exbolt 63 has a thickness of 0.63mm and it is about 24% more durable than strings of comparable thickness. With the high hitting sound and the fast repulsion you do not give the opponent a chance to counterattack.
