My right knee looks a lot smoother than my left. It does not bow outwards and seems to follow a smooth course. Whereas my left knee is all over the place even when I am comfortably spinning - it seems to wobble as i bring it towards my chest. If I pedal harder I find my foot wanting to turn more and more inward. Is this due to tightness in certain muscle groups or more likely to be due to poor bike set up. My saddle height is adjusted to the highest point without allowing for any pelvic tilt and my cleats have a good degree of float in them but are set as my feet stand (which is different for both feet - outwardly rotated for my right foot and straight - almost inwardly rotated for my left)
