Brunswick's successful relaunch of the Quantum product line continues with the Quantum Bias. This bowling ball features high-density Quantum Mushroom high RG Asymmetric cores along with a thicker urethane coverstocks. This thicker coverstock offers durability, longevity, and massive hitting power. This ball is unique in that each core has a unique design to compensate for the gross weight of the ball, the core's dynamics, and the balls hook potential. The Bias uses Brunswick's ECA-XR coverstock formula and the all-white color gives a unique look as well as enhanced hooking power due to the traction additive found in Brunswick's white pigment.
