The ultimate in time trial and triathlon performance, the Giro Aerohead Ultimate MIPS TT Helmet combines premium TeXtreme carbon fibre with a premium Zeiss Optics attachment and MIPS impact protection technology to create a fast, light and comfortable helmet. The hybrid carbon fibre and in-moulded EPS construction ensure perfect balance, protection, and aerodynamic performance.
Giro Aerohead Ultimate MIPS TT Helmet
Giro Aerohead Ultimate MIPS TT Helmet
Quite possibly the fastest time trial or triathlon helmet ever created, the Giro Aerohead Ultimate MIPS TT Helmet has a carbon fibre construction for the fastest and lightest aero profile.
The shell of the helmet is constructed from TeXtreme carbon fibre, which is lighter and stronger than other carbon composites. This combines with the in-mould EPS liner to provide protection. The aero profile speaks for itself in terms of results, with Rohan Dennis recording the fastest ever average Tour de France prologue speed wearing the helmet in 2015.
Inside the helmet, the MIPS (Multi-Impact Protection System) acts to dramatically reduce crash impacts by creating a rotational interface between your head and the helmet. This offsets impacts by spreading the force through the helmet rather than through your cranium.
A premium time trial helmet such as this one would be nothing without clear vision when you are travelling at speed. Thankfully, Giro has enlisted the help of the best in the optical business in the form of Zeiss Optics for the visor. The large visor offers superb optical clarity and a large 180˚ peripheral field of vision.
The Zeiss technology lens is both water-repellent and anti-fog treated, with vents placed at the top of the lens to provide cooling airflow. The visor can be quickly and easily attached and detached with the magnetic clips and can be flipped up too.
Giro's comfortable and easily adjustable signature fit is provided by the Roc Loc Air system. this allows for micrometric one-hand adjustment on the move.
Please note: Helmets that are sold on Sigmasport.co.uk are certified with a European CE EN1078 standard. Specific countries may have their own certification, which is legally required. Please check your specific country requirements and check with the manufacturer to see if the helmet has received any additional certification.
