In a world’s first, Yonex has utilized top-class Namd graphite, creating the ASTROX 77 badminton racquet. Current top players in the world have many playing styles to maximize their chance to take points from their opponent. Smashes are utilized to break opponents with a hit that rapidly descends to the floor with power and accuracy. Combined with a fast play speed, smashes of varying angles and power help players rout their opposition. ASTROX 77 uses a world's-first, new dimension graphite material, Namd, which greatly improves the adhesive degree of carbon fiber and resin by attaching nanomaterial directly to carbon fiber. From the initial movement of the player to the impact, the new dimension graphite is difficult to harden, and the shaft extends and accumulates energy due to the speed of the fast swing. Since follow-through of the swing is smaller after direct impact with the shuttlecock, the swing speed drops and the new dimension graphite regains hardness and strengthens the resilience of the shaft, allowing the energy to explode rapidly before returning to its original state. In addition, we use the grip end, the frame top and the joint, to distribute weight throughout the racquet. The transition to the next shot can be performed smoothly with a rapid succession. The ASTROX 77 is an attack-orientated model which can lead a high-speed game with a design which can deliver powerful, steep smashes allowing for more chances with the shuttlecock.

ISOMETRICEnlarged Sweet Spot ISOMETRICTM technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRICTM delivers greater control without sacrificing power. ISOMETRICTM is a Trademark of Yonex CO., LTD. |

NAMDRevolutionary Graphite A world-first, new dimension graphite material, Namd, greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the graphite fiber.In high performance racquets, it is common to combine nanomaterials with resin that connects graphite fibers, but in Namd, nanomaterials are directly adhered to the graphite fibers and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle. |

NANOMETRICLightweight NANOMETRIC* improves the bonding strength between the carbon fibres enabling us to take racquet shaft construction to another level. By reducing the amount of carbon in the shaft to make it 60%* thinner than a conventional racquet whilst retaining stiffness, YONEX has created a revolutionary lightweight racquet with lightening head speed and control. *NANOMETRIC is the new material which applies the NANOALLOYTM Technology of Toray Industries, Inc. *approximate measurement when compared to a conventional racquet shaft, tested by YONEX
