The protective panels are exclusively fashioned from shatterproof polycarbonate and fitted with the classic pins to attach tear-offs. If, despite this, the polycarbonate front lens should get so scratched over time that performance is impaired, this can easily be replaced. The full-rim adapter with the moulded optical lenses can be removed and refitted to a new front panel. The only frame colour available at present is black. The full-rim adapter also ensures that only curved optical lenses with free-form technology can be fitted. Personalised lenses tailored to the user deliver optimum peripheral image quality, which supports the vestibular system and thus enhances safety on a bike.
