Thought they looked cool I have a couple of sets from my buddy. He knows the guy that made them back in the day. They are cncd from a solid block of aluminum and have a removable spider. I have one set like this with the decals and another that is just plain. They were some of the only cranks back in the day that could hold up on the local free ride trials in chilliwack. My buddy snapped xt 's, race face, and kooka cranks. These were the only ones that would not brake. They were popular with free riding and trials bikes back In the day. They only stopped making them because the interfaces kept changing and it cost too much to keep up.
