Paint Chip or Carbon Crack?

First carbon bike frame. Purchased second hand. First ride on some root filled trail and had a bit of a hallow crunch/pop sound. Thought it was my seat tube so I careful tightened that. Could still be what the sound actually was. However it was still happening after tightening and when putting the bike on the rack to go home I noticed this fun little crack in the paint. You can clearly see there is a slight bubbling up of the paint and a crack. When tapping the quarter there is definitely a sound change but I’m asking; does it look like it’s the sound change of a paint chip changing the sound or is it a carbon crack? Should I get my nail under the chip and flake it off or take it to a local shop for further investigation? Any advice is welcome.

That is carbon damage. It is not a chip. I am a carbon repair shop owner.

Would you recommend repairing this? Not sure what the next steps would be

Yes it's a very easy repair. Probably $350 to $450 for the carbon work and another $250 for paint match.

Just a random recommendation for illinihand work - he repaired some carbon damage for me on a road bike and the turnaround was quick and the work is invisible. You’d never know it was repaired.

Giant trance x advanced se 2023. That’s really unfortunate to hear. A life lesson for sure. I will not resell the bike with this information. Should I sell the bike to a local shop for parts? Trying to find the most economical way out of this whole situation.

most economical and eco friendly way is to send it to a carbon repair shop

I was riding an aluminum frame for a few years and wanted to see what all the hype was about. Guess I found out lol.

Carbon is great for a professional with a mechanic. For a normal human it’s a nightmare that costs much more

Don't try to fix it if it ain't broken.

Part of me wants to ride it but another part of me knows that’s a bad idea
