Mizuno JPX850 Iron with Power Frame

The JPX850 breaks all the normal rules of golf equipment – with a face that flexes past the 0.83 COR competition limits placed by the USGSA and R&A on drivers. The breakthrough in ball speed and distance is achieved through increasing the flexible portion of the clubface. A reinforced frame around the clubface makes it play effectively larger, without increasing its size. As important, the framework ensures ball speeds are consistently high across the entire clubface and that high COR is not created at the expense of feel or control.
