Hi all, can anyone help me? I'm looking to replace a hub casing on my shimano rs30 rear wheel, basically I had a mishap and the chain jumped between the cassette and the spokes. The spokes came off ok ish, but the chain was mangled and the hub casing is proper damaged, making the wheel unusable at the moment, I was wondering if anyone out there has one, may be a worn out wheel, or damaged rim just sat in the garage doing nothing!!! I'm in need off it! For some reason you can't buy it from shimano, please can anyone help???
