My dh is arguing with me on this issue. After my big mountain bike ride last year I not only lost my visor some place in the desert but the hard plastic that surrounds the helmit is cracking. Do I need to replace my helmit? I am bummed I don't have my visor anymore. And I don't know if you can replace them. At least my local lbs store said you can't. Of coarse I am sure they would like me to buy a new one.
