    Revolutionary 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.

    AERO+BOX Frame


    Combines solid hitting feel and quick swing.


    Enlarged 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.

    Rotational Generator System

    Counterbalanced Weight Distribution

    By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly, with rapid succession.

    Super Slim Shaft

    Reduced Air Resistance

    The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.

    Energy Boost CAP PLUS


    Uniquely shaped cap which maximizes shaft performance.The front allows the shaft to flex, while the sides arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.
