MTB is old blue because when I got my road bike it became the old bike and is blue in color. The new road bike (not so new now) I have not realy named it yet. It's a trek 2200 bright yellow in color and looks fast but unfortunately I am slow on it. Flash comes to mind but again I am slow. As far as talking to my ride as we go along it is a given. As I ride strictly alone (not by choice) it can be pretty loud at times. No one around to hear me except for the critters, or the occasional car/truck going by at 70+.
