An asymmetric design, numerous features, protection, and comfort – these are the ingredients for an urban helmet in 2021. The Alpina Brooklyn is a helmet for the city. Although the design language of the Alpina Brooklyn is understated, it stands out. Asymmetric air intakes at the forehead, matte solid colors, a short visor, large ventilation openings on top that form a protective angel with the padding inside, and an LED light at the back. With the push of a button, it activates a surrounding light chain, permanent light, or flashing light, providing additional safety in an urban environment. To ensure the Alpina Brooklyn fits perfectly on the head, the Run System Ergo Flex + is integrated. A fine ratchet mechanism allows for almost stepless size adjustment via a dial. The bike helmet is manufactured using the Inmold process, where the inner shell made of Hi-EPS is foamed under high pressure and heat into the outer shell. The result is lightweight and safe helmets – for a pleasant ride through the city.
