because of how the dent happened, the handlebar should be structurally okay. If this was a dent from a crash, I might worry about damage. In your case, though, you have an annoying cosmetic blemish.

It's possible that the grip might not hold as securely to the bars as before, but you don't have worry of structural failure while riding.

Now all you need is a camera that can focus on close-up subjects.
