Giro, the helmet manufacturer, has insisted it "plays by the rules" after the UCI announced a review into time trial helmets, a move seemingly triggered by the launch of the new Giro Aerohead II.
In a post on Instagram on Wednesday evening, Giro revealed that the UCI had authorised the prototype of the Aerohead II to be used in racing in 2024, in October 2023. Crucially, the letter says: "The authorisation is thus provisional and may be amended or withdrawn at any time."
