●Safety: In the in-mould manufacturing process, shock-absorbing helmet material (EPS) is foamed into the impact-resistant outer shell - for a stable and durable connection ●Fit: Zoom Ace FF adjustment system with an adjustment wheel allows individual adjustment to the respective head circumference ●MIPS: movable, low-friction plastic shell in the helmet supports that the brain is better protected in the event of an inclined impact by reducing rotational movements ●Breakable umbrella attachment: in the event of a fall, the umbrella absorbs the impact slightly, but then breaks away so that the head does not fall back into the neck ●ASC – Ambient Sound Channel: ABUS communication channels are channels at the level of the ears – so you can easily hear and perceive your surroundings even in the full-face helmet ●Ventilation: 11 air inlets and 6 air outlets for optimal ventilation - so no heat build-up under the full-face helmet ●Details: unisex bicycle helmet with chin guard for men and women, includes removable cheek padding. Size specification in centimetres corresponds to the head circumference of the wearer
