Went around the city today and apparently, 13" is the smallest that people work on. Am I relagated to heating it myself and then using vise-grips with a rag to get the fix aside from buying a new one?
Why chance a poor repair and have problems later? Contact drichardson@core.com and get a used one from him. Once the metal is bent, it's distorted and weak. Bending back may break it. A wheel is too important for a dangerous or shoddy repair.
Depending on how bad the rim lip is, you could repair it yourself. Local deformation of 1/4 over 1" should dress out with wood blocks and a mallet. If the rim is really bent, just replace it.
