Right now my concern with balance may be more in my head. When at a stop with your feet on the ground, most of the weight (rider and bike) is behind your knees so the muscles in your lower legs are managing all the weight. If you slip up and let the bike lean too far, the way the weight is distributed has a leveraging effect making it harder than you may anticipate. I'm thinking that having the additional weight of loaded panniers would only increase this problem. Your thoughts?

Also, could you include any information you have on the front rack/bag you outfitted your bike with?
