Last week, we reported controversial changes to the UCI's technical regulations that will take effect from 2026, including new limits on handlebar width and helmets. Here’s what you need to know, in brief:
- From 2026, handlebars used in road or cyclocross competition must be a minimum of 400mm wide (outside-to-outside), or 320mm from hood-to-hood. The UCI says the move is aimed at limiting extreme and unsafe aero positions.
- Wheels will be limited to a maximum rim depth of 65mm. The UCI will also introduce distinct helmet regulations for road races and time trials.
- Officials say the rules are designed to level the playing field and ensure “sporting fairness”. But the response has been mixed, with experts saying the handlebar rule ignores the needs of female riders.
- A source told BikeRadar that the handlebar changes would be “hugely discriminatory against women and smaller men”.
- The UCI also confirmed it will not support the One Cycling plan. The scheme proposed remodelling the sport to aid the financial stability of teams.
- This week, it was revealed the UCI will also trial gearing restrictions.
