SIYOUEI No.821 Ultra Frame Pole Ver.II Red

A tough ball frame made of extra super duralumin, which is about half the weight of titanium and has titanium-class strength. The titanium bolt part is equipped with an air intake function by long hole processing, which is considered difficult, and realizes a comfortable start. All the parts are machine-cut and the parts are reviewed according to the size of the ball frame to establish the strength as a frame while maintaining the lightness.
