Mysterious Slowing Wheel
While reinstalling my back wheel I noticed that it wasn't spinning completely freely as a wheel should. I thought it was the brakes that I had just reset since the sound of the rubbing was near there, but even after letting them loose again the friction continues. I don't know where it's coming from. It seems like there is an audible rubbing whenever a certain spot on the wheel rotates past, but there's nothing touching it at all!
I cleaned my drive train recently just by flossing with some rags and degreaser. I only mention that because after staring at the spinning wheel with a confused look on my face for 10 minutes I figure it's got to be some sort of internal resistance that's slowing it down.
Anyway, what should I do? It's not enough resistance that I even notice while riding, but something certainly seems up since the front one spins so freely. Maybe back wheels are always like this and I just never noticed?
