I've only done 2 tours last summer (5day-4day) with the BoB as my hauler and I didn't feel any sway at speed (40K+) and had no difficulty while breaking (Avid BB5 Disc). I didn't feel it on the downhills or the flats but when I got to the hills it was quite a push. It was my last tour that I felt I could use some assist if I wanted to continue touring......Some pic's from the SunShine Coast tour #2
