What Actually Causes Ball Speed?

Tech Talk Episode #26

In golf, “ball speed” is one of those buzzwords that gets tossed around in every fitting bay and launch monitor session. But what really determines how fast the ball leaves the clubface? Is it all about the core of the golf ball, or do other layers matter too?

In this week’s Tech Talk, Dean Snell answers a question from Dale in Ohio that gets right to the heart of the matter.

The Short Answer: It’s All the Layers

Dean explains that ball speed is influenced by the entire construction of the golf ball, not just one part. When you hit a driver, the golf ball compresses roughly one-third of its diameter—about half an inch. Since a golf ball is 1.68 inches in diameter, that means you’re well into the core on every solid driver strike. But that also means you’re engaging all the cover and mantle layers along the way.

The Role of the Core

Yes, the core matters. Core materials are made from specific rubber systems, similar to mixing ingredients for a cake. The choice of materials and the quality of the process determine how resilient and fast that core will be. Cheaper rubber systems can feel softer but may be slower and less consistent, while premium systems are designed to maximize energy transfer and maintain performance over time.

Mantle and Cover Layers Count Too

While the core does the heavy lifting for energy transfer, mantle layers and the cover also contribute to ball speed. These layers are typically 30–50 thousandths of an inch thick. They can add speed by controlling spin and helping maintain structural integrity during impact. In high-performance golf balls, each layer is engineered to play a specific role in optimizing both distance and control.

Why Compression Matters

Ball speed is closely tied to compression. A ball that compresses properly for your swing speed will store and release energy more efficiently. Too soft, and you may lose ball speed. Too firm, and you might struggle to get enough launch or spin. This is why fitting matters—choosing a ball that matches your game can unlock extra yards without changing your swing.

The Big Takeaway

Ball speed isn’t magic, and it’s not just the core. It’s the synergy of the core, mantle, and cover working together. Every layer contributes, and the quality of the materials and construction plays a huge role. For golfers chasing more distance, focusing on overall ball design—and getting fit for a model that suits your swing—is far more important than obsessing over any single component.
