The ASTROX series features the Sonic Flare System, which strategically places high modulus graphite at the bottom of the frame for enhanced power and stability, boosting shuttle acceleration. The Energy Boost CAP PLUS has a unique shape that maximizes shaft performance, allowing flex at the front while stabilizing the racquet face with its curved sides to prevent twisting. The AERO Frame reduces air resistance, resulting in faster swing speeds and improved maneuverability for quicker, more responsive shots.
