I have an aluminum frame bike, the bolt for one of the water bottle mounts will not come out. There is a threaded ring set in the seat tube of the frame. When I turn the bolt in either direction, the ring turns with it. I have not found a way to grip the ring without risiking damage to the frame.
Has anyone else ever seen this situation and if so have you found a solution?
