Product Technology

• NAMD : 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.

• Isometric™ : 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.

• Soft Feel Core: Cuts Vibration

The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan.

• AERO+BOX Frame

Combines solid hitting feel and quick swing.

• 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.

• Slim Shaft: Extra Slim Shaft

Thinnest, Strongest Ever Produced by Yonex

Cutting edge NANOMETRIC carbon technology is used to produce an ultra-thin, ultra-tough, aerodynamic shaft, created for a stronger and more intense shot.

• 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.
