Pro Cycling Tried to Ban One Gear Combo—Then a Competition Court Said ‘No.’ Here’s Why a Bike Part Fight Could Decide the Next Wave of Safety Rules
A proposed UCI “54×11” maximum gearing trial was pitched as safety—but Belgian authorities said the process wasn’t transparent or proportionate, and it hit one supplier hardest. Now the sport’s next safety rules may depend on how they’re justified, staged, and enforced.
Key Points
- 1Track the flashpoint: the UCI’s 54×11-equivalent gearing cap was halted after Belgian authorities questioned necessity, proportionality, and process.
- 2Understand the market impact: the protocol singled out SRAM’s 10T cassette design, creating immediate compliance burdens in a concentrated drivetrain market.
- 3Watch what comes next: future safety rules will need transparent criteria, non-discriminatory design, and staged pilots that avoid irreparable harm to teams.
A bicycle gear sounds like the smallest unit of professional cycling: a cog, a chainring, a few grams of metal you never notice until it slips. Yet in the past year, a single number—54×11—has turned into a fight about safety, market power, and who gets to write the rules of the sport.
The Union Cycliste Internationale (UCI) wanted to test a new technical standard that would cap riders’ maximum gearing at an equivalent of 54×11—a limit on how “big” a rider’s hardest gear could be. The trial was meant to begin 1 August 2025, with early application slated for a major WorldTour race in China that October.
SRAM, one of the two dominant drivetrain suppliers in elite road cycling, challenged the move through competition proceedings in Belgium. The Belgian Competition Authority (BCA) agreed—urgently—ordering the UCI to suspend the trial by 13 October 2025, just before the Tour of Guangxi (14–19 October 2025), the first planned testing ground. On 20 May 2026, the Market Court (Brussels Court of Appeal) dismissed the UCI’s appeal “in its entirety,” keeping the suspension in place.
What looks like a narrow technical dispute has become a referendum on governance. How should cycling balance real safety concerns with the economic consequences of equipment rules? And what happens when a safety standard lands hardest on one manufacturer—especially when the sport’s supply market is already concentrated?

The rule that started it: a maximum gear equivalent of 54×11
Why 54×11 matters in the modern drivetrain era
The controversy is not that riders might be forced onto “easy” gearing. The controversy is that the rule ties a safety policy to a very particular technical assumption about the smallest cog.
The 10-tooth problem: UCI’s protocol singled out SRAM’s setup
Under a strict cap equivalent to 54×11, riders on 10T systems would need some form of mechanical blocking or limitation to prevent accessing the hardest combinations. In other words, the standard didn’t merely limit gearing in abstract; it created an immediate engineering and compliance issue for one of the sport’s major equipment ecosystems.
“When a rule explicitly calls out one supplier’s hardware, the burden shifts from ‘sporting policy’ to ‘market impact.’”

The safety case: what the UCI says it was trying to do
Those points matter because safety is not a pretext in cycling; it’s a live issue. Speeds are high, courses are often technical, and crashes can be catastrophic. If governance has any first principle, it’s preventing preventable harm.
SafeR’s role—and the politics of “stakeholder consultation”
From a governance perspective, that’s a familiar pattern: pilot first, then scale. From a competition-law perspective, pilots can be especially risky if they create sudden commercial harms before the rule’s necessity is properly established.
Necessity and evidence: where the argument tightened
According to the BCA’s 21 May 2026 press release summarizing the judgment, the Market Court held that the UCI failed to justify why the standard was necessary and proportionate to improve rider safety. That’s not a claim that safety doesn’t matter; it’s a claim that the UCI did not meet the burden of showing that this particular cap, designed this particular way, was the right tool.
The UCI has said the protocol came via SafeR recommendations and stakeholder consultation.

The business reality: drivetrain markets, dominance, and who bears the cost
The BCA described SRAM as “one of the two main drivetrain suppliers” in pro road cycling—and “the only one” that did not have a product meeting the 54×11 standard at that time. In a market that concentrated, the effect of a technical standard can resemble the effect of a market access rule.
The immediate economic effect: compliance isn’t just flipping a switch
- Hardware changes (different cassettes or chainrings)
- Firmware or mechanical limitations to block certain combinations
- Re-testing and re-homologation logistics
- Team-level changes to spares, setups, and service procedures
The Belgian authority concluded the standard was likely to cause serious harm that is difficult to repair to SRAM, with harm also extending to teams using SRAM. That “teams” point is not incidental: pro teams depend on equipment performance and continuity. A rule that forces rapid mid-season or pre-race changes doesn’t just inconvenience a brand; it can reshape competitive preparation.
Four numbers that define the dispute
- 54×11: the proposed maximum gearing equivalent (the heart of the standard).
- 10T: the smallest cog size the protocol explicitly noted for SRAM road cassettes.
- 1 August 2025: the date the UCI planned to begin implementing the test protocol at selected races.
- 14–19 October 2025: the dates of the Tour of Guangxi, the first planned application—driving the “urgency” that triggered interim measures.
- 13 October 2025: the deadline by which the BCA ordered suspension, one day before the race began.
- 20 May 2026: the Market Court judgment date dismissing the UCI’s appeal.
Those dates and ratios aren’t trivia. They show how quickly a technical document became a high-stakes legal event.
The Belgian Competition Authority steps in: interim measures on 9 October 2025
What the BCA said competition law requires for technical standards
That framing is familiar across regulated industries. If a rule changes market access, procurement, or competitive viability, the process must be clean—and the rule must be demonstrably necessary.
The BCA’s prima facie findings: process and disproportionate effects
Crucially, the BCA also focused on harm: the standard was likely to cause serious harm that is difficult to repair to SRAM, extending to teams using SRAM. That harm analysis is what makes interim measures possible: authorities move fast when delay would make later remedies meaningless.
What the BCA ordered the UCI to do
- Immediate suspension of the maximum gear ratio standard.
- A prohibition on the UCI imposing transmission ratio limitations (or equivalent measures) until a new safety measure is adopted through a compliant procedure or until a merits decision.
The BCA said safety standards must be proportionate, objective, transparent and non-discriminatory, and must not unduly restrict competition.
— — Belgian Competition Authority (press release, 9 Oct 2025)
The Market Court’s “No”: 20 May 2026 and the appeal dismissed
Appeals of interim measures often turn on jurisdiction, urgency, and whether the authority overreached. The Market Court’s decision, as summarized by the BCA, reads less like a technical correction and more like a validation of the authority’s approach.
Jurisdiction: why Belgium could act
That point may sound procedural, but it has real implications: global sports bodies can be subject to national competition scrutiny when their rules affect markets and actors connected to that country.
The court’s core findings: transparency, proportionality, and safety justification
- A prima facie restriction of competition because the UCI failed to apply transparent, objective, and non-discriminatory criteria in developing the standard.
- The UCI failed to justify that the standard was necessary and proportionate to improve rider safety.
- The risk of serious, imminent and irreparable harm to SRAM and SRAM-equipped teams was correctly assessed.
Those are not marginal holdings. They go to the core of how sporting rules must be built when they reshape commercial competition.
“Safety is a legitimate aim; the court’s message was that legitimacy doesn’t excuse a weak process.”
— — TheMurrow (Pullquote)
What this means for cycling: governance, safety, and innovation after the ruling
For the UCI and SafeR: a higher burden of proof
- Transparent about criteria and evidence
- Objective in its technical choices
- Non-discriminatory in its market effects
- Proportionate to the safety goal
That’s a tall order for any sport, especially one trying to respond to public concern about risk. Yet the court’s reasoning (as summarized) suggests that if the UCI wants rules that touch equipment markets, it will need to treat them more like formal regulation than like internal policy.
For SRAM and rival suppliers: competition law as a design constraint
For competing suppliers, this also matters. A rule that seems to disadvantage one competitor today could disadvantage another tomorrow if innovation takes an unexpected turn. Competition law can function as a stabilizer, preventing governance from locking the sport into a single technical pathway.
For teams and riders: stability, but also uncertainty
Until the UCI produces a better-justified and procedurally robust safety measure (or wins on the merits later), teams will operate in a holding pattern: safety pressure on one side, legal constraint on the other.
Key Insight
Practical takeaways: what readers should watch next
If the UCI tries again, the process will matter as much as the policy
- A clearer publication of criteria and evidence linking gear limits to safety outcomes.
- A demonstrably non-discriminatory technical design that does not effectively single out one supplier’s ecosystem.
- A staged implementation that avoids irreparable commercial harm during “testing.”
Teams should treat equipment rules as legal risk, not just technical risk
Fans should resist the false binary: “safety vs. innovation”
The larger lesson is uncomfortable but useful. A sport cannot modernize its safety regime by stumbling into equipment regulation and hoping the market absorbs the shock.
What to watch next
- ✓Publication of criteria and evidence linking gear limits to safety outcomes
- ✓Non-discriminatory technical design that doesn’t single out one supplier ecosystem
- ✓Staged implementation that avoids irreparable commercial harm during testing
- ✓Signals of a merits investigation outcome or a redesigned safety measure
Frequently Asked Questions
What was the UCI’s “maximum gear ratio” rule?
The UCI proposed a trial technical standard to cap riders’ maximum gearing at an equivalent of 54×11 (54-tooth chainring and 11-tooth smallest cog as a reference). The protocol was planned for selected races beginning 1 August 2025, with enforcement checks at events chosen through a SafeR-recommended process.
Why did the rule affect SRAM more than others?
The UCI’s protocol explicitly noted that SRAM road cassettes include a 10-tooth (10T) smallest cog. A 10T cog allows a higher top gear than an 11T cog for the same chainring size. Under a 54×11-equivalent cap, SRAM setups could require mechanical limiting or different gearing to comply.
What did the Belgian Competition Authority decide in October 2025?
On 9 October 2025, the BCA imposed interim measures suspending the UCI’s maximum gear ratio standard. The authority said that safety is legitimate, but standards with economic consequences must be proportionate, objective, transparent and non-discriminatory, and it found the standard posed a risk of serious, hard-to-repair harm to SRAM and teams.
Why did the BCA act so quickly?
The BCA cited urgency because the first planned application was set for the Tour of Guangxi (14–19 October 2025). It ordered the UCI to suspend implementation no later than 13 October 2025, one day before the race began. Interim measures are designed to prevent harm that would be difficult to remedy later.
What did the Market Court decide in May 2026?
In a judgment dated 20 May 2026, the Market Court (Brussels Court of Appeal) dismissed the UCI’s appeal “in its entirety,” leaving the BCA’s interim suspension in place. The court confirmed, per the BCA, concerns about transparency and non-discrimination and said the UCI failed to justify necessity and proportionality for safety.
Does this mean the UCI can’t regulate equipment for safety?
No. The Belgian authorities’ position, as stated in their releases, is not that safety rules are illegitimate. Their point is that equipment standards with major economic effects must be adopted through a fair, transparent process and must be necessary and proportionate to the safety objective.
