I picked up the bike new this September, only 500kms on it, noticed these lines on the frame below the seating tube after some indoor training. Not sure if carbon cracks or paint cracks, would not mind some opinions as am I’m new to carbon frames generally. I can feel something when I run my hand over the lines, so not just superficial.
Thanks!

Did you clamp it?
Get a coin, size of Australian 20cent. Dont know where you are. Tap somewhere away from the damage, and then in the area of the damage, it should sound the same and a healthy tap tap, not a dead thud. If it does the carbon mats are delaminated, don’t ride it, it will fail.
