The only thing wrong with those skewers as they were designed with the assumption that users had at least a double-digit IQ. (Apparently some people screwed them in with the lever open.)

I actually didn't know they were titanium until after I stopped using them. They aren't ferromagnetic, and they are light, so I assume they are titanium. They have aluminum levers and fittings.

A little bit of aluminum oxide. Same thing happens with an aluminum seatpost in a steel frame. It can get stuck. In this case, it also gets stuck. Keep the frame dry. It should be fine.
