Yonex Nanometric

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.
Rotational Generator System

Yonex rotational generator system applies the counterbalance theory in Yonex racquets. Weight is distributed throughout the grip end, frame top and the joint for maximum control. This ensures a smooth and rapid transition to the next shot.
Yonex Namd

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 Yonex Namd, nanomaterials are directly adhered to the graphite fibers and resin is greatly increased. This major improvement in Yonex racquets produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle.
Isometric Head Shape

Yonex’ square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length. This shape produces a larger sweet spot in all directions.
New Grommet Pattern

Yonex’ new single-pass grommet hole construction provides more grommet holes and fewer shared holes than other brands. This permits for a more high-performance stringing pattern.
Solid Feel Core

The built-in solid feel core in Yonex premium racquets reduces harmful miscellaneous vibration at impact. This technology, called “solid feel core” is a feature of all Yonex racquets manufactured in Japan.
Aero+Box Frame

Yonex frames are contoured differently on different parts of the loop. Some areas feature an aerodynamic shape to reduce air resistance. Other areas feature a box shape to provide strength and power. This combination offers a quick swing with a solid feel.
Built in T-Joint
Moulded deep into the layers of graphite where the frame connects with the shaft, the YONEX Built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free.
Super Slim Shaft

This is the slimmest shaft ever produced by Yonex. It vastly reduces air resistance whilst providing maximum feel.
Yonex Control Support Cap

The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability.
