Yeah, I know. Two of my bikes have racks. I was hoping that it would not be needed for some of my other bikes.

Typically, my commuter has a rack and I always carry my two panniers, even though I usually don't need them. But, at times, I would like to ride with one of my "faster" bikes that I don't want a rack on, but might need to carry more than the smaller seat bags I have now.
