For what it’s worth, I have a set on my cruiser/rain board for about 6 months and have withstood all kinds of abuse, skating through puddles, pouring rain, mud, dirt, salt etc, and haven’t really slowed down at all.
So I’m quite impressed by them. I have no idea why mine are doing so well while lots of other people have bad experiences with them.
Maybe because I never jump down anything higher than a curb on that board? Who knows.
