That is absolutely a concern. It falls into the same kinda thing where you can stand on an empty coke can as long as it is in perfect shape, but as soon as you put the smallest dent in it, it will colapse. The bars want to bend at the bend, it is the "stress riser" of the bar, but the saving grace is that most minis don't have a lot of traction. I use 1 1/4 x .120 wall mild steel and only run as much bend as needed. If it needed too much bend, I would redesign the system to alleviate some of the stress or run a bigger tube.
