cshell, what do you have yours set to?
I'd give what I have my computer set to, but I haven't really measured it for better accuracy (roll for ten revolutions, measure the distance traveled, divide by 10... or roll for a hundred and divide by a hundred, whatever). I just told it to use what the chart said for 700x23.
