is it the same for bicycle helmets? i mean is there also a point that you should replace them even if there was no damage impact on it?
It's mostly BS so they can keep you buying new helmets. How you can tell when the styrofoam is degrading is when after a ride and you've sweated you'll see black particles on your head stuck to the sweat...that stuff is the styrofoam now beginning to degrade now it's time to replace the helmet. Most of my helmets last 8 to 12 years before the styrofoam material begins to shed.
I use to ride a MC years ago and my helmet was 15 years old by the time I got rid of the bike and it was still fine.
