Brunswick Kingpin Ultra Low RG Core

It's all in the crown with the Brunswick Kingpin! Revolutionary innovation comes to bowling ball design with the Kingpin Ultra Low RG Asymmetric core delivering easy revs and immense overall hook. Surrounded by this core is the all-new Dynamicore formula, which yields less compression upon impact wit the pins. Rather than wasting energy within the ball, more energy is expended right where you want it - the pins. This leads to more pin action and higher scores.
