It only happens on poorly built skis. Rivets are completely unnecessary unless you're trying to salvage a ski that has started delaming on the tip or tail. If your friend seriously thinks skis need to be tacked together by rivets you should tell him he's a dumbass. Also, there isn't much you can do to prevent a ski from delaminating, it just kind of happens.
skis shouldn't delam ever, if they do it's a manufacturing problem, and tell your friend that he's a jackass, rivets are a fashion thing, they don't actually do anything
to delam skis? its pretty fucking hard, unless theyre like dyanastar. I watched testing on delaming and other things at a ski factory and it takes SO much pressure. Youd be more likely to break them in half.
rivets served a purpose when ski construction was more 'primitive', but nowadays, yes, they are mostly for show. ive lost a few rivets in my PE's and theyre still going strong.
Actually the "slapping" effect that sometimes occurs during landings causes your skis to shear like crazy. Thats why cap skis dont do so well in the park. Anyway, long story short...its not that tough to delam a pair of skis in the park. I have delamed 4 pairs myself.
what dose this have to do with any thing there talking about delaming skis and ur just like ya my skis are geting a hot wax to make me hit biger jumps ?
