The Fearless will turn the bowling world upside down! The Contra core is the first to feature Durability Optimization Technology (DOT) – a patent-pending technology that creates an unrestricted drill area. The Fearless will produce easy length, relentless backend motion and outstanding pin carry on medium oily lane conditions. Whether you need to strike out to win a tournament or shoot 300, get Fearless! Clean your ball with Brunswick’s Big B Bowling Ball Cleaner after every use to reduce oil absorption.
