The Malaysian Tenpin Bowling Congress (MTBC) has announced a major equipment rule change, confirming that slow oil-absorbing high-performance urethane bowling balls are now disallowed in all tournaments hosted by MTBC and its state affiliates in Malaysia.
The decision takes effect immediately and applies to all MTBC-sanctioned competitions across the country.
According to the MTBC, the ruling followed an extensive review process that included discussions with technical experts, coaches, and elite athletes. MTBC also considered global trends, local lane conditions, and research conducted by the United States Bowling Congress (USBC).
In its official statement that was shared on Monday morning, the MTBC explained that the move is intended to protect competitive integrity and support long-term athlete development within Malaysia.
The MTBC stated that slow oil-absorbing urethane equipment can alter lane conditions more quickly than intended, which may affect fairness for players using different styles and equipment types.
MTBC also highlighted concerns related to equipment governance and enforcement. The governing body noted that changes in urethane balls over time can make it difficult to distinguish natural wear from intentional modification, creating challenges for consistent tournament control.
MTBC added that the situation will continue to be monitored and may be reviewed again in the future.
In September 2025 USBC announced, that beginning January 1, 2026, slow oil-absorbing high-performance balls will face strict new limits at national tournaments. In some events, they will be banned entirely; in others, only models manufactured at a minimum 78D hardness will be allowed.
