- 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.
- IC ELASTOMER
Found throughout the inside of the DUORA 7 frame, this soft elastomer material increases shuttle hold and accumulates energy.
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.
Soft 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.
- Ultra PEF
The shaft is constructed using ‘Ultra PEF’ – ultra poly ethylene fibre – which is light enough to float on water yet able to withstand immense forces. these characteristics allow for maximum shock absorption.
- 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.
