TECHNOLOGIES USED IN DUORA 77 RACKET:
Duora 77 racket features DUAL OPTIMUM SYSTEM:
A new frame design that allows a single racquet to excel on both forehands and backhands: One side is built with our Box frame design for increased shuttle-hold and repulsion on forehand shots, while the other is built with our Aero Frame design to immediately repel the shuttle on backhand hits.

Duora 77 racket features NANOMETRIC β:
Grounded in nanoscience, this material binds carbon fibres tightly together one-by-one without any gaps, for enhanced strength.
Duora 77 racket features ISOMETRIC FRAME:
The square-shaped isometric frame shape of the Duora 77 racquet 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.
Duora 77 racquet features NEW GROMMET PATTERN:
The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.

Duora 77 racquet uses BOX+AERO FRAME:
Box frames are stronger and stiffer. It allows for more power transfer.
Aero frame minimizes air resistance. With low air resistance player’s swing speed will increase.

Duora 77 racket uses 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.

Duora 77 racquet uses 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.
