Brussels, Belgium – September 20, 2025 – American cycling component manufacturer SRAM has launched formal legal proceedings against the Union Cycliste internationale (UCI), lodging a complaint with the belgian Competition Authority (BCA) on Friday. The action stems from the UCI’s recently announced trials of maximum-gear ratio rules, which SRAM contends are demonstrably harmful to its business interests.

The Core of the Dispute

The UCI unveiled plans in June to test maximum gearing configurations during select professional cycling races, ostensibly aiming to curtail top speeds and enhance rider safety. This protocol dictates a maximum gear ratio of 10.46 meters per pedal revolution, roughly equivalent to a 54×11 gear combination.While Shimano and Campagnolo equipped teams face minimal disruption, as their systems readily accommodate an 11-tooth bottom cassette cog, SRAM’s technology presents a challenge.

SRAM has invested significantly in drivetrain systems utilizing a 10-tooth cog, resulting in a maximum attainable ratio of 49×10, which calculates to 10.44 meters per pedal revolution – slightly below the UCI’s limit. This discrepancy places SRAM-sponsored athletes at a competitive disadvantage.

Technical Implications and Potential Solutions

Addressing this issue technically presents a substantial hurdle for SRAM. The company asserts that developing a compliant cassette would necessitate a complete redesign, a process projected to span years and severely impede its ability to compete effectively in both racing and the broader cycling market. In the immediate term,SRAM states the protocol mandates disabling its 10-tooth cog,limiting gear options for riders.

interaction Breakdown and Allegations of Bias

SRAM alleges repeated attempts to engage the UCI in constructive dialog regarding the potential impact of the new regulations were rebuffed. The company claims UCI leadership declined to address their concerns or the rule’s underlying justification. Beyond the direct impact on performance, SRAM is contesting the methodology behind the UCI’s decision-making process.

SRAM characterizes the initial testing as based on a “non-clear and non-scientific” survey, heavily skewed towards Shimano-compatible setups. They further contend there’s no empirical evidence linking higher gear ratios to increased crash risk. SRAM also argues the testing framework is inherently flawed, as it fails to assess systems like theirs, effectively predetermining the outcome.

EU Competition law and broader Implications

SRAM’s complaint to the BCA frames the UCI’s actions as potentially violating EU and Belgian competition law, specifically Articles 101 and 102 of the Treaty on the Functioning of the European Union (TFEU). These articles address anti-competitive agreements and abuse of a dominant market position. SRAM argues the gear restriction distorts the market, limiting choices for teams and consumers who rely on its products. Moreover, they express concern that the public perception of their gearing as “non-compliant” is causing reputational damage and jeopardizing future sales.

The company fears that a permanent restriction could drive retailers and Original Equipment Manufacturers (OEMs) away from SRAM products,diminishing its market share in the high-performance road drivetrain sector. This reflects a concern that the issue extends beyond mere sporting regulation, reaching into the realm of fair business competition.
