Redemption is a beautiful thing and even better when we are talking about a high performance Hammer bowling ball. The Hammer Redemption Solid ball is bold in color and bold in ball motion. With the combination of the Redmeption core and the Aggression NE Solid coverstock this ball hooks like crazy and requires plenty of oil. This bowling ball utilizes DOT and is Carbon Fiber Infused! DOT allows you to drill anywhere on the ball and offers toughness to the ball. Carbon fiber is one of the toughest materials on earth. Hammer decided to add this material to the outer core of this ball for added strength and durability allowing them to offer an incredible 2 year warranty.
