how dangerous/ difficult is it to ride with an unevenly loaded bike? I need to carry tools and such for work , and i am tired of carrying 20 pounds on my back every day. I have a pair of ghost brackets, and have found a nice Pellican case that would hold my tools( it is also a roller, so I would not have to carry it). I don't need 2 of them. How bad of an idea is it to ride with 20 -30 pounds hanging off one side of your bike?
