Numbers as 900 Global publishes them, checked 21 October 2026. 900 Global doesn't say which ball weight these numbers are for. Drilling changes how a ball behaves, so a pro shop's layout matters as much as these numbers.

What the numbers mean
RG 2.460. That is lower than 99% of the 134 current reactive and urethane balls in our table, so it sits on the low side. Storm says "a low RG ball will rev up quickly and roll smoothly."
Differential 0.056. Higher than 91% of the balls in our table. Storm says "a high differential ball will create a sharper angle of entry into the pins."
Hybrid reactive cover. Hybrids mix solid and pearl; Storm says they suit bowlers who need a ball "that can adapt to a variety of lane conditions."
Symmetric core. Storm says symmetric balls have "RG values consistent across all axes" and a smooth, predictable roll.
USBC allows an RG from 2.447 to 2.813 inches and a differential of at most 0.060 inches (Equipment Specifications Manual, March 2026). Our ball spec table lists every current ball we track, and who makes bowling balls covers which company owns 900 Global.
