Bowling Ball Balance Hole
Bowling ball balance holes have been a topic of discussion in recent years. The United States Bowling Congress (USBC) made a rule change in 2020 that eliminates the use of balance holes in bowling balls. In this article, we'll take a closer look at what a balance hole is, its purpose, and the impact of the USBC rule change.

What is a Balance Hole?

A balance hole is a hole drilled into the surface of a bowling ball to adjust its weight distribution. Bowling balls are manufactured with a specific weight block that determines the ball's weight distribution. A balance hole is drilled into the ball to shift the weight distribution to the desired location.

The purpose of a balance hole is to fine-tune the ball's reaction on the lane. By shifting the weight distribution, bowlers can adjust the ball's hook potential and ball motion. A properly placed balance hole can help a bowler achieve the desired ball reaction, making it an essential part of a bowler's arsenal.

The Impact of the USBC Rule Change

In 2020, the USBC made a rule change that eliminates the use of balance holes in bowling balls. The rule change is based on the belief that balance holes give an unfair advantage to bowlers, as they can alter the ball's dynamics and make it easier to strike.

The USBC rule change states that any hole in a bowling ball that is not used for gripping purposes is considered a balance hole and is not allowed. This means that bowlers are no longer allowed to use balance holes to fine-tune their ball's weight distribution.

The rule change has caused controversy among bowlers and ball manufacturers. Some bowlers believe that the rule change is unfair and limits their ability to adjust their ball's reaction on the lane. Ball manufacturers are also affected by the rule change, as they must redesign their products to comply with the new rules.

The USBC's decision to eliminate bowling ball balance holes is based on data that suggests that balance holes give bowlers an unfair advantage. The USBC conducted extensive research on balance holes and found that they can increase a ball's hook potential by up to 3 degrees. This can make a significant difference in a bowler's game and can give them an unfair advantage over their opponents.

The USBC's decision to eliminate balance holes has been met with mixed reactions from bowlers. Some bowlers support the rule change, believing that it will level the playing field and make the game fairer. Other bowlers are opposed to the rule change, arguing that it limits their ability to adjust their ball's reaction on the lane and takes away an important tool in their arsenal.

Alternatives to Balance Holes

With the elimination of bowling ball balance holes, bowlers must find alternative ways to adjust their ball's weight distribution. Here are a few alternatives to balance holes:

Surface Adjustments: Surface adjustments are the most common way to adjust a ball's reaction on the lane. By altering the surface of the ball, bowlers can change its hook potential and ball motion. Surface adjustments can be made by sanding or polishing the ball's surface.

Weight Block Adjustments: Weight block adjustments can also be made to fine-tune a ball's reaction on the lane. Weight block adjustments involve drilling the ball to change its weight distribution. However, under the new USBC rules, any holes drilled into a ball must be used for gripping purposes only.

Thumb Slug: A thumb slug is a small piece of material that is inserted into the thumb hole of a bowling ball. Thumb slugs are used to adjust the fit of the ball and can also be used to adjust the ball's weight distribution.

In conclusion, balance holes have been an essential tool in a bowler's arsenal for many years. However, the recent USBC rule change eliminates their use, citing an unfair.
