Brunswick Quantum Bias Bowling Ball

Quantum Bias is the first asymmetric ball in the Quantum line. Our ECA-XR coverstock combined with the Quantum Mushroom High RG Asymmetric core gives strong hooking motion with excellent pin carry on oily lane conditions.

The Quantum series has been designed with 3.5 times more coverstock for improved durability, performance longevity, and incredible hitting power. The enhanced Coefficient of Restitution results in the pins flying faster for greater pin action and more strikes.
