So I have this maddening come-and-go type of problem. Every so often, and for no reason I can ascertain, I can feel a slight vibration in my pedals while riding, like it's some sort of feedback from the BB. It also seems that my front hub is resisting a little bit, and I'm wondering if the two problems are linked. Is it possible that both need to be repacked? The bike hasn't been out in the rain or anything, but it does live outside during the day. Any help is totally appreciated.
