Yonex Astrox 88 D Game Badminton Racquet is designed with Nanomesh Neo which is a material that promotes quicker shaft take-back. Nanomesh Neo ensures a stronger more flexible frame, while increased shaft flex creates maximum power. Aero+Box frame combines a solid hitting feel and quick swing. The Isometric equalizes the length of the main and crosses strings in the string-bed, enlarging the sweet spot for more consistent accuracy even on off-centre hits. By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly with rapid succession. The new shape allows the shaft to flex, which ensures the maximum effect of Namd and stabilizes the Racquet face by preventing the shaft twisting, increasing control. Specification: Flex – Stiff.
