It's not trolling. The wheels just aren't safe. That's all there is to it.

Look at the link Traffic Jammer posted. That site has been around forever, and hasn't even been updated since 2003. It has page upon page of reports of Spinergy Rev-X wheels basically exploding with no warning, even when the wheel had been checked for cracks. People have broken arms, shoulders, backs, and anything else you can think of as a result of these wheels failing. Most of them were riding in a straight line or turning, not doing tricks.

Using these wheels, especially now that they're this old and have an unknown history, is putting your health at serious risk, if not your life, no matter what you weigh or what kind of riding you're planning to do.
