While bright colors and fun patterns might seem like the most impressive aspects of bowling balls, there’s more to them than meets the eye. In fact, ball design is so important that some professional bowlers travel with up to ten different varieties. This guide explains what goes into a bowling ball and why experienced bowlers choose theirs with such care.

What Are Bowling Balls Made Of?

There are two main bowling ball designs. The first, older type is known as a three-piece and is composed of a shell, filler material, and a weight block. The weight block is placed close to the outer shell and is used to fix any imbalance caused by drilling the gripping holes. It keeps the physics of the ball from veering too far away from those of a standard sphere.

Most modern balls are considered two-piece designs, although they can contain anywhere between two and four components. The main features of a two-piece design are the core and the coverstock. Because coverstock materials can be expensive, an outer layer made of polyester or glass beads mixed with resin is used to coat the core. This also allows manufacturers to experiment with how density affects performance. Once the core and outer core have been joined together, they’re coated with coverstock to create a finished bowling ball.

How Do These Materials Impact the Game?

Coverstock

Coverstock materials have the most impact on overall performance. There are three types of material that can be used to form this outer surface: plastic, urethane, and reactive resin. Each has a different effect on the ball's traction as it travels down the lane. 

Plastic is the most slippery and therefore tends to travel in a straight line. It’s also the easiest for newcomers to the sport to control. Reactive resin has the most grip and can be used to create dramatic hooks and curves just before the ball reaches the pins. Urethane falls between the two. Since it’s easier to control than reactive resin, it’s popular among bowlers who are just learning how to throw hooks.

Core

Built from heavy materials such as graphite, a core's shape is just as important as what it’s made of. Together, the shape and density of the core control how the ball spins. 

There are a vast number of designs on the market, from simple light bulb cores to complex geometrical shapes. Serious mathematical measurements go into designing these shapes, and they’re often unique to specific manufacturers.
