Forks also fail under impact at the top of the legs.I'm not a fan of taking risks, hence looking at replacement options. A full csu might be the way forward, but equally happy with spares if I can't repair safely and economically.
No idea how they became bent, bought them on a whim to see if I can resolve with either straightening or replacing the steerer, if not strip and keep the spares for other forks or buy a replacement csu.
