The Synthe leads the way in road helmet design offering great aerodynamic efficiency with a supreme fit and excellent ventilation
The Synthe™ is the pinnacle of road helmet design, combining the performance gains of an aerodynamic profile and light weight with great cooling power to enhance rider comfort and efficiency in road rides and races. The compact form slips through the air with ease across multiple yaw and head angles, and offers greater cooling power than the Aeon.™ Key features include the Roc Loc® Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride.
The Wind Tunnel ventilation system combines 26 active vents with internal exhaust channels that thrust cool, fresh air over and around your head whilst forcing heat and stale air out. This significant increase in air channelling makes a difference that you will immediately feel and appreciate especially when cycling in hot/very hot conditions.
Giro’s X-Static pads provide extra comfort and have anti-microbial properties to help keep your helmet fresher for longer. The pads are also machine washable.
Roc-Loc Air Fit
The Roc Loc Air system enhances comfort and stability while adding a new dimension to ventilation and cooling. With a unique design that suspends the helmet slightly above the head, it creates an optimised path for air to flow through the helmet with a Venturi effect that increases efficiency of the vents and internal ventilation channels. Like the acclaimed Roc Loc 5, it also offers micro-adjustable tensioning and vertical positioning adjustments, so you can fine-tune the fit and tilt on the fly with one hand. It’s a new level of skull-hugging luxury and cool that only Giro can provide
Eyewear docking ports
Eyewear docking ports allow you to carry your glasses safely when you don't need to wear them anymore.
If you have an accident in any helmet it's a good idea to replace it. Giro offer the peace of mind that if you have an accident wearing one of their helmets they will replace it at a reduced price. Find out more here.
Performance cycle helmets offer unrivalled levels of protection with the absolute minimum of material. They are ridiculously light and feature a series of huge vents, designed to scoop up air and direct it over your head. On long, hot climbs, the difference is noticeable.
In order to cycle on the road or compete in a race it may be a legal requirement in your country to wear a helmet certified to a specific standard or an international equivalent. All helmets sold on Wiggle are certified and labelled with a European CE EN1078 standard.
