The UCI has issued an update to the new rules it proposed earlier this year, backtracking on its previous stance and shrinking the minimum handlebar width limit it previously set out.
The previous proposal, issued in June but set to come into force on January 1, 2026, stated a minimum width of 400mm at the handlebar's widest point – a widening of the prior existing limit of 350mm – as well as a new minimum-distance limit when measuring between the inner-most points of the two shifter hoods. This was set at 320mm.
