When I was young there were no such things as lawyers lips. It just takes a few evolutionary throw backs to
forget about bike maintenance, get hurt, sue the company for not designing for stupidity and voila
everybody pays. Didn't one school just ban soccer balls from their field because a teacher got hurt by one.
If you keep your skewers locked in the same position you just have to look at them to know they are OK,
or heaven forbid bend down and check them.
