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.
In 2025, REDSON will enter the era of fully grommet-free frames.
100% grommet-free, utilizing high-precision technology to deliver maximum strength, superior racket response, and enhanced performance of the hitting sound.
When restringing, there is no need to replace plastic grommets. The fact that being non-consumable means it is energy-saving and green (ECO-FRIENDLY), and it also significantly improves stringing efficiency.
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.
Better Strength, Lighter Weight
-
The diameter of the eyelets at the 3, 9 and 12 (top) o’clock positions on the grommet-free frame is 1mm. 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, combining the advantages of SHAPE 01 and SHAPE 03.
Woven Carbon Fiber
High-technology composite WOVEN carbon fibers in its structure. The characteristic weaving angles and arrangement of the carbon fibers have improved the strength and torque of the frame and shaft by 20%, while generating an overall shock resistance for the racket.
