USBC RULE CHANGES
July 31, 2018 - Here is the bowling ball technology study link to keep you informed on what you should do with your equipment! Below are the dates that the new rules will take effect!
The specification increases in static weights take effect Jan. 1, 2020. This will allow bowlers the opportunity to plug balance holes before the elimination of balance holes starting Aug. 1, 2020.
With the elimination of balance holes, bowlers may have up to five holes for gripping purposes and all gripping holes must be used on every delivery.
The rule change allowing only a dry towel to clean bowling balls during competition becomes effective Aug. 1, 2019. This eliminates the use of liquid cleaners of any kind during competition. This aligns with other changes to ensure equipment is not manipulated during competition. The change prohibiting a bowler from adjusting static weight during a competition by drilling grip holes deeper goes into effect Aug. 1, 2020.
