This year at Smoky Mountains we sheared our bolts off. I noticed it when we were moving the wheels and the other wheels werent moving too. The middle wheel with the two sprockets was just floating there. We removed them with grade 8 bolts and never had another problem. Please note we took 3 of the bolts out and only had 3 bolts holding on each sprocket, not a good idea, i dont know who decided that.
