My friend did the same on his. I pointed out however that the lower cage bolt that's fixed into the bash guard could puncture the downtube if smacked on something.
Not going to happen. That is a very strong hunk of aluminum. If you strike something hard enough to bend in, probably damaging the rivnuts in the process and still have enough force to push a 5 mm nylock into that frame, that is the least of the worries.
Debate? Bikes are made for riding not pushing.
