I notice a huge difference in speed when I ride my touring tires (32c) vs racing slicks (23c), but I imagine if you are out riding to ride, you may just notice that it was easier to push the lighter tire, and rather than taking advantage of that to go fast, kept at your usual comfortable pace.
Each time I was "timing" either tires I was going at a pace where I was pushing myself moderately- trying to always keep pedaling rather than coasting, pushing my legs a bit but not killing myself either. I don't "think" I lagged because of the lighter tires being easier to push- I was really looking forward to cutting some time off my ride and thus I was pedaling with some enthusiasm. Yes, my route has lots of rolling hills and several short very steep hills- actually not much flat riding around here at all. ....but what do you mean by "where rotating weight will make a difference"? -can you explain?
I did have a cold at one point and am still slightly feeling the residual effects, but my first skinny-tire timing was right before that hit. I also note that the weather has been slightly breezier overall than before I changed the tires- it coming into winter and all...
It's frustrating to work against changing weather conditions in trying to make accurate comparisons. But you'd think at least ONE of my rides since changing tires would be faster than on my old fat tires!
