A flimsy bag with weight in it hanging from the handlebar/brake lever in close proximity to the front wheel and spokes. What could possibly go wrong and how could that possibly affect Larry's day? Just askin'.
I know a musician who could be careless with her handlebar bags. Had one probably engage the front tire and she lost her embouchure. (Ability to correctly shape her lips for clear, pure flute sound.) She never did get it back.
