Drilling and tools

The new Quadfire inner core produces an RG that stores energy for the backend reaction and a differential for controlled track flare.  The 15# ball has an RG rating of 2.55 and differential of .043. The Reverb outer core of the QZ1 is a low-density polyester resin with pin piercing hardness and strength. Rather than absorb impact energy, this outer core reverberates energy as it explodes through the pins.

Sources and method

Specs. Motiv published specs, as shown on BowlersMart’s original Motiv Quadfire core page (2022), as published by the manufacturer.

Baseline. The baseline is 265 in-stock, published reactive and urethane balls. Plastic and polyester covers, 2-piece, 3-piece and pancake cores, missing covers and missing RG or differential values are excluded.

Percentiles. Percentiles are the share of baseline balls with a strictly lower or higher value; ties are not counted.

Nearest cores. Nearest cores are ranked by distance on standardized 15 lb RG and differential, with the same symmetric or asymmetric shape preferred among near ties (distance bands of 0.1).

Mass bias. Mass bias is compared among asymmetric balls with numeric mass bias only.
