Dave's point is a good one to know. I assumed all the weight went onto the headset. Headsets consist of bearings, bushings. Thought weight here might be detrementral to it's wear. My wife's bike came with a rear rack, but it has not braze ons. Often when she goes on errands, I go along with her on my bike, which has rear panniers; and that takes off some of the heavy load for her.
