Chain rattle in high gears
When I am in high gear (small cogs in back) I get a noise that sounds like the chain rattling against the front derailleur. It happens whether I pedal or not, so I can be coasting down a steep hill and still hear the rattle with each bump in the pavement. The front and rear derailleurs (Campy Record) **** accurately and easily, and my LBS says nothing is wrong. To my mind, its almost like the chain is too long, so that in high gear there is not enough tension to keep it from bouncing around the front der., but if that was the case I don't think it would shift so well.
