While giving my new used bike a thorough cleaning today, i saw this on the top tube
And now, of course im freaking out a little bit, mostly because im not the original owner, so i wont have any warranty coverage. I know carbon is very strong, but how can i find out if this is just a crack in the paint, or if there is damage to the frame? Its a very tiny hairline crack, about 6" from the seat post. I wont care if its just the paint, but if its more, im gonna be really sad. Ive had it out on a total of 3 rides and just now saw this
