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.
Frame/Wind Resistance Chart
The Dimple-Shape frame weakens the wake and thus lowers the drag by 10%.
Conventional frames create a thicker wake with more drag.

SHAPE SG Incorporates 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.
Notices About Stringing
Please take notice when stringing: bevel the string tip with a diagonal plier and insert string into the eyelets in a parallel manner.
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.
