Yesterday I saw something like a crack in the carbon fork of my roadbike. Now I don't have any clue if this is a really a crack or just the paint. Maybe someone can help me or tell me how to find out. Thanks!

EDIT: Thanks again for all your answers. I took the bike to my dealer, he communicated it to the TREK warranty department and I got a brand new fork. No bigger problems, just some e-mails and pictures (from the dealer, he also sent the broken fork in). Thumbs up TREK!
