I recently took a curb harder than I should've and my bike's rear tire now has a flat spot. Since my tools are currently all elsewhere I can't fix it myself. When I took it into the local bike shop the tech said that it was too badly bent to fix by simply adjusting the spokes (I agree with that), and that it would be cheaper to get a new rim than to have them fix it. I've attached an image of the rim. The walls of the rim have also bent inward, that made getting the tire off a little interesting. I'm thinking that if I pull all of the spokes out I can beat the flat spot out with a rubber mallet. My concern with this however is that working the metal like that will weaken it to the point where it will randomly break one day while I'm riding. I'm probably going to get a new rim anyways because I need this bike operational as soon as possible. However is this rim safe to fix, or should I just put it in the recycling?
