Rain, sweat, heat, and dirt all take their toll and cause grips to wear down over time. Changing your grips frequently can be one of the most cost effective ways to maintain your equipment, and can add more consistency and control to your shots.
As a rule of thumb, you should regrip your clubs once per year, or every 40 rounds. Keep in mind that grips lose a significant amount of their original feel long before they become hard and slick. Because it happens slowly over time, most golfers fail to notice it. That's important to remember because just a tiny, imperceptible slip at contact will be magnified by many yards by the time the ball reaches its target.
Many people make it a habit of regripping their clubs at the beginning of each golf season. Don't worry about the time you will be without your clubs! All installed grips are guaranteed to be completed and ready for play within 24 hours of drop off.
