I don't know why, but the suspension fork on my Roam doesn't seem to get in the way. I'm as fast on my Roam as I am on a Trek FX, with the benefit that I'm not sore after my rides with the Roam. As suggested, it is best to test ride bikes with both a rigid and suspension fork.
What psi was it? the max psi written on the tire has nothing to do with actual pressure you need, it is just a safety maximum pressure. I have about 25 psi on my 2" front tires (probably could have 20 psi) (I'm 175#)
funny how they give the Roam only 38mm tires from factory. Go to 50 mm an that coil suspension becomes meaningless. and no, rolling resistance on real world surfaces does not increase.
