My Pilot 1.2 has a Bontrager HCM CF fork. Don't know much past that. Last couple of rides I've had a noise on the bike. When riding over cracked/rough pavement. Sounds like a fingernail tapping on the fork (that hollow high pitched sound, sound more like tapping on the fork than if I tap on the Al frame). I noticed the headset was slightly loose so I tightened it (didn't seem loose), did another ride and the noise was worse, so I don't think it's the headset.

Digging deeper I noticed a chip of paint coming off the dropout. Is that normal? I didn't think it was painted, but I guess it is. I don't see a crack, but I plan to look more closely tonight.
