COEFFICIENT OF RESTITUTION
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. 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.
COVERSTOCK
The all-white color of the Quantum Bias offers enhanced hook characteristics because of the unique traction additive found in our exclusive white pigment. The Bias also has 3.5 times more coverstock for increased durability and hitting power.
