In the battle against the clock, it's all about saving watts and saving seconds. POC's Cerebel saves you both. POC collaborated with their Watts Lab, team Garmin-Sharp, and Volvo to make the Cerebel aero, fast, and safe. The shape of the helmet is shorter so crosswinds are a non-issue. The soft molded EVA foam rear makes it comfortable and improves aerodynamics in the transition from head to your back, even if you don't have the perfect aero tuck. The included, removable Zeiss lens adds to the Cerebel's slipperiness and actually enhances contrast out on the road for better visibility. The dial in the back gives you a custom fit too.
