Brunswick Kingpin Rule Bowling Ball
The Kingpin success continues with the Brunswick Kingpin Rule bowling ball. This ball takes the proven Kingpin Ultra Low RG core and wraps it with the successful ECA-XR coverstock that is used on the Quantum Bias. This core and cover pairing make it perfect for heavy oil conditions while giving great hook, backend and pin carry. Rule the lanes and your competition with the Brunswick Kingpin Rule.
