We rode a 200km Audax on Saturday and had a perpetual clicking noise from the rear of the Santana. It was present when freewheeling, so isn't gear related. I took a close look at the wheel yesterday, and established that the cones are correctly tightened and the bearing silky smooth. There was a lot of crud in the mudguard, but we hacked this out and went on a test ride to find the noise still there. The spokes are all tight, and although the wheel is a little out of true, it's not contacting with the brake blocks, in fact yesterday we tested it with the Vee brake disconnected and still no joy. The disc rotor is perfectly true. Unlaiden and upside down, the wheel runs free and silent. Computer magnet and sensor have also been eliminated.
Any thoughts? I think this may be slowing us down too as the ride on Saturday was a lot harder than it should have been.
