I guess we have a terminology issue here. Rolling resistance, what exactly is that defined as? Drag + friction? Factors affecting such? I don't know.
Drag is your biggest problem when on flat land. When going uphill, not gravity is the issue.
I don't know what "rolling resistance" means.
I take it to mean, basically where the rubber meets the road. Friction.
But, the topic is talking about "wind". Which I would take this to mean, we are talking about drag.
