My 1992 Trek 2300 is Eroding at the joints where the carbon joins with the aluminum, only on the top bar though, on the fork side. There is about a 3/4" circle of white clear coating. Right now it looks like the clear coating has just pulled away from the carbon, and the aluminum is slowly decaying. One guy at my LBS said it might be dangerous to ride, another at a diff LBS said it was fine until i hear it pop (sounds safe) From a poor description, what do you guys think? I tried to take some pictures but they are coming out horrible.
