Can the strength of a bent frame be preserved when it is straightened?
Proper straightening of metal will not weaken it and a frame is no exception. A frame repaired by a skilled professional will be as strong as the original. This pre-supposes the frame has not previously been damaged by improper repair. Over-heating metal, improperly working metal and repair of metal that is kinked can result in weakening. It is very important to select a true profession for frame repair. Once metal is damaged by improper repair, it can rarely be restored.
