When Safety Rules Collide with Competition Law - The UCI Gear Ratio Decision

In October 2025, the Belgian Competition Authority (BCA) issued an interim measures decision^[1] that suspended the International Cycling Union's (UCI) newly announced technical standard limiting the maximum gear ratio permitted in professional road cycling events. The decision effectively blocked a safety-driven measure just hours before its first application. It came in response to a complaint by SRAM, a bicycle components manufacturer and one of the principal suppliers of transmission systems for professional road bikes.

The decision illustrates a fundamental tension at the intersection of sports regulation, competition law, and the discretion of sports governing bodies to set the rules of their games. It reveals how competition authorities are increasingly scrutinising the governance processes of sports organisations. In particular, the BCA's reasoning suggests that good intentions and legitimate objectives are insufficient: the process of standard-setting is as relevant as the rationale.

This article examines the BCA’s assessment under applicable competition law, identifies some takeaways for sports governing bodies (SGBs) and legal practitioners, and explores the broader implications for sporting autonomy.

This article examines the BCA's assessment under applicable competition law, identifies takeaways for sports governing bodies (SGBs) and legal practitioners, and explores three specific implications of the decision:

1. Why the case extends competition law's procedural obligations to genuinely disinterested regulators for the first time.
2. Why competitive harm now begins at the moment a rule is announced rather than enforced; and
3. Why Belgium has become a priority jurisdiction for equipment manufacturers and teams seeking rapid interim relief against sports federation rules.
