Yonex Astrox 01 Feel Badminton Racquet is targeted at advanced players and designed to deliver power from hit after hit. 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 control support cap provides an 88 percent wider flat surface compared with an ordinary Racquet for easier gripping, fast follow-through and the sharpest manoeuvrability. Aero+Box frame combines a solid hitting feel and quick swing. Specification: Flex – Hi-Flex. Frame – Graphite. Shaft – Graphite. Length – 10mm longer. Weight/Grip – 4U (Avg. 83g). String Advice – 4U 20-28lbs. Color – Black/Yellow.
