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 vents 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 blinking light, providing additional safety in the urban jungle. To ensure the Alpina Brooklyn can be perfectly adjusted to the head, the Run System Ergo Flex + is integrated. A fine ratchet mechanism allows for almost continuous 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.
