The King is back and this time, stronger than ever. Wrapped around the outside is the ECA-XR solid coverstock, the same cover as seen on the Quantum Bias. Finished to 500/2000 Siaair Micro Pad, the Kingpin Rule is the perfect arsenal piece for heavy oil conditions.
Inside, the Kingpin Ultra Low RG with DynamiCore technology, as previously seen in the Kingpin Rule's predecessors, you can expect MORE hook and backend with insane carry. Show the competition who RULES.
The Kingpin features a new innovation in outer core technology called DynamiCore. This leap in bowling ball technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry. DynamiCore is blue and will be noticeable when drilling into the bowling ball.
