Hammer wants you to make a statement with the Hammer Statement Solid High Performance Bowling Ball. This ball uses the high traction Aggression Solid CFI coverstock which is finished with a 500/2000 grit sanding. The coverstock offers lots of traction in heavy oil and lots of continuation downlane all the way through the pins. The Statement core in this ball has a very low RG with a high differential as well as a strong asymmetric core. This core design helps the ball rev up in heavy oil conditions. The design of this core places the majority of the mass at the bottom of the core which assists in storing energy. This bowling ball is Carbon Fiber Infused! Carbon fiber is one of the toughest materials on earth. Hammer decided to add this material to the inner core of this ball for added strength and durability allowing them to offer an incredible 3 year warranty.
