The Synthe™ is the pinnacle of road helmet design, combining the performance gains of aero efficiency and light weight with great cooling power to enhance rider comfort and efficiency.
The Synthe™ is the pinnacle of road helmet design. It offers impressive cooling power, minimal weight, supreme fit and streamlined aerodynamic efficiency. It is a true synthesis of all features a modern rider wants in a high performance road racing helmet.
The difference is clear in the wind tunnel - our extensive testing reveals that the Synthe is nearly as efficient as the fastest time trial helmets. But the Synthe's greatest attributes are comfort and ventilation. At it's heart you'll find our Roc Loc Air fit system. Micro adjustments allow you to custom tune tension and fore-aft tilt with one hand and a patented design suspends the helmet over the top of the skull, allowing airflow to pass freely over your head. Cooling power is further boosted by elaborate internal channeling and a series of massive vents; the Synthe sets a new bar for ventilation.
You no longer need to choose between aerodynamics and cooling power - with Synthe you get everything, all wrapped up in a compact and sleek silhouette.
