Today my Road Bike started making an obnoxious chirping sound. Could not tell if it was front or back. The sound start when I hit about 17 mph and continue if I am pedaling or coasting. No brake rubs, shoe or pedal problems. Ideas?
Yeah, probably a hub seal. My front hub does that sometimes after riding in the rain. If it's a front, hold the wheel flat and dribble some chain lube where the axle penetrates the hub, while rotating the wheel.
