Re: pic: #1018's omni wheels
If by "special" you mean exotic, then you would be correct, the "spokes" are made of carbon fiber.
If by "special" you mean wierd, then you were correct. We had k'nex wheels with o-rings in place of the lexan disks, but they kept slipping off when we were up against any force, so we had some lexan cut instead.
