Ha, ha, i am reviving this thread I guess. I for one took the Trans America Bicycle route from Kansas to Florence, OR. I rode a 'Bent and pulled a trailer. Got up to 60 mph several times going down hills. The entire trip . . . never had a problem. I think this is a personal preference. I have both and use one on one trip and another on the other. Ho hum. . . . . Let's go riding!
