Also, a little off topic, but cleaning time is a good time to check the bottom bracket cable guide.

I've found they're only good for about 5-6,000 miles (might be better if I were more diligent about cleaning "down there" ).

Just a little visual inspection to make sure (1) it's clean, (2) the groove isn't so deep that the cable is hanging up in it, and (3) there's still enough of the guide left that the cable isn't contacting the frame.
