I cannot even stand the idea of my knees coming up behind the bars. OTOH, I'm not really sure what I'll want in a bar right now. One of the wider bars would help, but I think I'm going to wait for a bit more. I'm doing fine on with the original bar for now, I just cannot wrap my fingers around the grips since the clearance is that tight between my knees and the bar, but I don't find it unnatural to ride with my palms on top of the grips and fingers on the brake levers.
