I was hit from behind by a car and it bent my rear wheel. It's bad enough that it feels like I'm going over a bump at every wheel rotation. The rim is lateral and radial out of true. It's a 700c aluminum alloy rim.
Is it repairable by hitting it with a rubber mallet and spoke tensioning?
If I buy a new rim, how long does it take to remove old rim and install a new one? What kind of tools do I need besides spoke wrenches?
