I've recently noticed that when I pedal, my knees wobble from side to side, ever so slightly. It's more exaggerated when I'm "putting down the hammer" (ie accellerating past walking pacewink: but it's still present even when I'm coasting along. I'm not talking wild shaking of the legs or anything. I'd estimate maybe a few millimetres from the straight. I've tried to correct it but cannot. So two questions: 1. Do I need to concern myself with this? 2. If so, how do I go about sorting it? My pedaling technique I thought was pretty smooth but I do seem to average out around 75 - 80 cadence, which I know is low. A while back I attempted to increase my cadence but found I just went slower and was spinning at the same rate.
