The term refers to adjustable components on a specific golf club model designed to influence its performance characteristics. These components allow golfers and fitters to fine-tune the club’s center of gravity, which directly impacts ball flight and trajectory. For instance, strategically positioning these heavier elements can promote a draw or fade bias, or optimize launch angle and spin rates.
The presence of these adjustable elements is significant because it provides a level of customization previously unavailable in golf equipment. This allows for a more precise fitting process, ensuring the club’s performance aligns with the golfer’s unique swing characteristics and desired ball flight. Historically, golfers relied on fixed club specifications, limiting their ability to optimize performance based on individual needs. The adjustability offers a significant advantage by allowing for in-depth fitting sessions.
