Replace an old helmet or a helmet with damage. The helmet is designed to absorb shock by partial destruction of the shell and liner. This damage may not be visible. Therefore, if subjected to a severe blow, the helmet should be destroyed and replaced even if it appears undamaged.The helmet has a limited lifespan in use and should be replaced when it shows obvious signs of wear.
Helmet parts lose strength over time, so even if the helmet has not been impacted or damaged, replace it after three years from date of purchase.
Trek Solstice Mips complies with U.S. CPSC safety standards for bicycle helmets, the EU CE safety standards for bicycle helmets, and the AS/NZS safety standards for Australia and New Zealand.
