UCI rectifies and will allow narrower handlebars

The International Cycling Union (UCI) has backtracked on one of its most controversial measures, the minimum limit on handlebar width. After receiving criticism from teams, cyclists, and biomechanics, the organization has reduced the minimum measurement between brake levers, which now goes from 320 mm to 280 mm.

UCI backtracks and reduces minimum handlebar width

The initial proposal, presented in June with an effective date of January 1, 2026, set a minimum width of 400 mm at the widest point of the handlebar and 320 mm between the inner tips of the levers. This would have made the vast majority of the peloton illegal, as they are used to using narrower handlebars with the levers turned inwards.

The reaction was immediate, especially in the women's peloton, where the use of smaller handlebars is a matter of ergonomics and safety. The International Bike Fitting Institute even released a statement denouncing that the UCI "had not taken into account human biomechanics or the safety of cyclists."

With the update announced today, the UCI confirms that starting in 2026 the handlebar must have a maximum total width of 400 mm (measured from end to end), the minimum distance between levers is now set at 280 mm, and the maximum flare (difference in width between the top and the curve of the handlebar) is fixed at 65 mm.

This way, extreme configurations that we saw a few years ago with completely twisted levers on tiny handlebars will continue to be pursued, but at least smaller cyclists will be able to maintain handlebars appropriate to their size.

In addition, the UCI has specified that the 280 mm figure will be monitored throughout 2026, with the possibility of being modified after a new round of consultations with teams and industry.
