Cerebel was developed in close collaboration with the Garmin-Sharp Pro Tour team (Cannondale-Garmin) and its drivers, Volvo and WATTS Lab. Cerebel is a compact aero helmet that has been designed based on wind tunnel testing and many CFD simulations. Cerebel excels thanks to its excellent results in many positions of positions in the time trial, which guarantees its high versatility even compared to the Tempor model. The back of the helmet is complemented by softened EVA foam at the bottom to minimize wind vortices and also to increase comfort. The visor is fromproduced by Carl Zeiss and is attached to the helmet with several magnets so that it is easy to replace and hold it exactly in place. The color of the lenses is always specifically chosen according to the requirements of the riders with an emphasis on the maximum increase in contrast and optical coherence. As with the Octal helmets, the Cerebel model has an EPS core with a specifically selected density and reinforced polycarbonate for maximum safety.
