Cracks in any type of shell may be a sign of increased brittleness, potentially increasing the possibility of further cracking that could cause lacerations if the cracked shell comes into contact with skin.

Do cycle helmets degrade?

Due to tiny impact after tiny impact over time, the EPS will gradually lose its volume making it less able to deal with the energy in the unfortunate event of an impact.
