I bought a new F'in derailleur because of that rock. Well, the derailleur was mangled and bent back recently and making other noises, so I figured it was the cause.
After yesterday's ride, the noise was so bad that I was convinced my bike was going to fall apart on every ledge I rode off of. In a fit of frustration I pulled the back wheel in the parking lot to check the hanger and hub bearings. I flipped the bike over to get the wheel back on, and heard a sound awfully like a rock inside of a tube. I realized what was going on and didn't actually see it fall out, but the noise is gone. Mrs. Snowaddict thinks its funny. I'm still pissed that I chased this noise for the last two weeks.
