  • Dual Optimum System

Power up your forehand and backhand with the Dual Optimum System

  • Nanometric™

NANOMETRIC* improves the bonding strength between the carbon fibers 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 that applies the NANOALLOYTM Technology of Toray Industries, Inc.

  • Nanometric DR

NANOMETRIC DR is a new carbon material developed by Yonex based on our unique NANOSCIENCE technology. Created from a material originally developed for next-generation space aviation by Toray Industries, Inc., this marks the first time it has been used within the racquet industry. By combining firm shuttle hold and high repulsion, NANOMETRIC DR puts the DUORA into a class of its own.

  • Isometric™

The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.

  • New Grommet Pattern

The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.

  • Solid Feel Core

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.

  • New Built-in T-Joint

‘NEW’ Built-in T-Joint is manufactured from a special lightweight plastic combined with epoxy resin and foaming agent that enhances quality and performance by increasing the stability of the shuttle on the string bed and through the air.

  • Super Slim Long Shaft

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

  • 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.

The Yonex Duora 77 (Red / White) is evocative, to say the least, but that's why you're drawn to it in the first place.
