Only one of my bikes has a disc brake and that is only the rear brake, so quite frankly I have no idea how people get bent discs. I just do not have much disc experience.
There of course is the airline baggage handler problem, they can bend or break anything. But if you take your disc off the wheel before you pack a front wheel, how do discs get bent?
Unless others on this forum start reporting lots of bent discs, I would be inclined to wait for it to happen before I bought an adjustable wrench to try to fix it.
