Description
Hammer Black Solid Urethane Bowling Ball
There isn’t a person on this planet that will argue against the fact that Hammer made the best urethane bowling balls back in the day. There is no doubt in our minds bowlers looking for the ball reaction that dominated the 80’s and early 90’s will find it in our new Black Urethane! This is ball is 100% real urethane and offers that true urethane reaction. 15# and 16# balls feature a thick shell. 14# balls use an outer core system.
FCC Rating (16) – The overall strength of the Black Urethane is perfect for medium to light oil patterns. This throwback will really excel on shorter oil patterns.
Overseas bowling balls are approved for all sanctioned USBC league and tournament play, but may not approved for PBA competition. Please check all rules and regulations before competition.
