In the face of ongoing criticism, the UCI has doubled down on various rulings made in the last week surrounding equipment in the pro peloton, including the introduction of a maximum handlebar width for road and cyclo-cross pros, and a trial of maximum gearing rules.

Under rules announced on June 12, from next year handlebars must be at least 400mm wide at the outer edge, and 320mm between the inner edges of the brake levers. An additional memo on June 17 confirmed that the UCI will trial limitations of gear ratios later this year, in a bid to reduce maximum speeds in the peloton.

The Cyclists' Alliance, the popular union choice for many female riders, is not affiliated with the UCI in the way that the Cyclistes Professionnels Associés (CPA) riders' association is, so is not involved in things like SafeR project.

"A test to limit the maximum gear ratio – approved by all families – will be carried out during a stage race in the second half of the 2025 season. The maximum gear ratio allowed in this context will be 54 x 11, i.e. 10.46 metres per crank revolution. The maximum gear ratio limitation aims to limit the speed reached in competition. It has been proven that the very high speeds reached by riders today are a risk factor for their safety."

The statement also reiterated and provided diagrams regarding maximum fork width and maximum rim height rules, as well as explaining that specific regulations around helmets – where a distinction is set to be made between what is allowed in time trials and what is allowed in road races – will be published at a later date.
