The frame cross-section formed by the string hidden grooves stabilizes the airflow during swings, reducing air resistance and wind pressure interference, ensuring smooth swinging motion.

The grommet-free frame addresses the problem of racket strings tearing easily due to abrasion against the carbon fibers in the frame. The eyelets are processed with fine polishing, allowing the strings to directly contact the frame and produce crisp, clear hit sounds.
※ Traces of pressure may show on the paint around the eyelets after stringing and are normal results of abrasion.
‧As it is smaller than the conventional eyelet diameter of frames with grommets, which is 2.1mm, the overall strength of the racket is enhanced by 10%.
‧This method eliminates the use of additional parts, i.e. the grommets, and as a result the frame weight is lessened by approximately 0.7g. To balance the weight in the racket, the wooden handle must also be made lighter by 0.7g. Therefore, the overall weight is reduced by around 0.7gx2=1.4g.
