To clarify even more.... I think he is talking about the diameter of the grab bar. Look's like that rack 'clamps' onto it.
I agree with Aaron though, I got one that's one piece with the desert bar like he has pictured. Wouldn't trade it for the world! Has helped absorb energy when I flipped hill climbing and the wide loops to the side help when ridding in mud (place my feet on them and rock back and forth) and when loading/moving bike by hand. They also help protect those rear fender flaps!!
With that Maier one clamped on to the grab bar, I can see the first time you wheelie over, slipping on the clamp and stuffing that rack right through your rear plastic/seat.
Just my $.02
