Hi everyone!
I recently bought a used road bike, and it came with a carbon handlebar.

After removing the bar from the stem, I noticed what looks like a small bulge or possible damage in the clamping area
(I uploaded a few pictures of the handlebar here:

Sorry, can't post clickable links yet!).

There are no visible cracks, but the surface doesn’t look smooth — it feels slightly raised.

Could this be structural or cosmetic? Is it still safe to ride for the next 500–700 km, or should I replace it immediately?

Thanks in advance for any advice!

(P.S. I'm a light rider, mostly doing flat/urban rides with some light climbing, no racing or sprinting.)
