UCI Approves New Aerodynamic Helmet Standards
The Union Cycliste Internationale announced updated regulations for time trial and road race helmets, effective January 2026. The changes aim to balance aerodynamic innovation with safety requirements.
Key changes include minimum ventilation requirements to prevent overheating and new impact testing protocols that better simulate real-world crash scenarios.
What Changes
Helmet tail length limits increase from 50mm to 65mm, allowing slightly more aerodynamic designs. However, all helmets must now pass side-impact tests at higher speeds than previous standards required.
Manufacturers have 18 months to update their lineups. Most major brands indicate their flagship models will meet the new standards well before the deadline.
Recreational riders are unaffected by UCI regulations but may benefit from the improved safety testing that will influence consumer helmet design.
