So anything over 100" starts to get more serious as far as riding style, gear etc etc etc?
I am just thinking more speed is better, I am not trying to win any races but would be nice for the speed to be there when I wanted it is what I am thinking?

I believe the xootr swift site states that at 90 gear inches and 120 rpm you will go 27 mph. Anything over 19 mph the aero drag increases a lot with each additional mph.
