Rotational Generator System – For Maximum Control. 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 a rapid succession. NANOMESH NEO – MAXIMUM POWER. Ensures a stronger more flexible frame, while increased shaft flex creates maximum power. AERO+BOX Frame – Combines solid hitting feel and quick swing. Control Support CAP – Sharp Maneuverability. The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability. ISOMETRIC – Enlarged Sweet Spot. Compared to a conventional round frame, a square-shaped ISOMETRIC racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRIC delivers greater control without sacrificing power. New Grommet Pattern – High-Performance. The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.
