Tow balls are cast iron I believe. Very strong but brittle and shouldn't be straightened or otherwise heated.
I'm no expert. Here a few questions. Why is it when a frame needs to be corrected after an accident, this is done cold?Why is it that both in Germany as well in Holland when cars at the yearly APK (Holland) IÜV (in Germany also for bikes) will be rejected when the inspector detects parts like trailer hooks have been heat treated?A friend's bike's handlebars were slightly bent after a drop. The mechanic at his dealer refused to bend it back to its original form, arguing it wasn't safe. I'm not suggesting I know the answers. I would like to learn more on the subject. Can you suggest what caused the metal fatigue of my main stand?
