By combining the Rotational Generator System, a technology shared by all rackets in the ASTROX line, with an overall reduction in weight, to perfectly match the swing speeds of intermediate players, the ASTROX 5FX increases maneuverability during power shots, such as smashes, ultimately increasing smash speed.

Additionally, the shaft employs the next-generation graphite material Namd, which helps it to quickly flex and return to normal, further increasing smash speeds.
