The Norm Duke Clear is a tribute to one of the most accomplished bowlers in history—Norm Duke—whose record-breaking legacy is defined by precision, consistency, and championship-level excellence. As part of the Ice Series, this ball is built for reliability, offering a clean, straight path that makes it an ideal choice for spare shooting or for bowlers just getting started. The Hex Core introduces a touch of modern performance, providing more dynamic motion than a traditional 3-piece core while preserving the predictability players expect. Finished with a durable clear polyester coverstock, it blends legendary style with everyday functionality. Whether you're refining your spare game or stepping onto the lanes for the first time, this ball delivers the confidence of a legend with every roll.
HEX CORE — WHEN STRAIGHTER IS GREATER
The Hex Core is designed to enhance predictability for every type of bowler. From a beginner’s first ball to a touring professional’s go-to spare option, this proven design delivers consistent, reliable motion you can trust.
CLEAR POLYESTER COVERSTOCK — STRENGTH, DURABILITY, AND PREDICTABILITY
When a straight shot matters most, polyester is the answer. Engineered for minimal friction and maximum control, it ensures the ball holds its line and performs exactly as expected. On challenging patterns where hook can work against you, take the oil out of play and trust polyester to get the job done.
