ROTATIONAL GENERATOR SYSTEM

ASTROX 88 SERIES TECHNOLOGIES 

By applying the counterbalance theory, weight is carefully distributed throughout the grip end, frame top and joint, enabling smooth transition between powerful shots for rapid, successive attacks. The innovative graphite “2G-NamdTM Flex Force” used in the shaft, characterized by its quick flex and snapback, maximizes shot power and advances the performance of the Rotational Generator System.
