Dual Optimum System
Grounded in NANOSCIENCE, this material binds carbon fibres tightly together one-by-one without any gaps, for enhanced strength.
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.
Combines solid hitting feel and quick swing.
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.
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.
