btw, I stumbled upon the following information in a review of rollers on fixedgearfever.com (
http://www.fixedgearfever.com/modules.p ... stance.htm). Sad thing is, I'd read various parts of the reviews in the past, but had never come across the page w/ the power numbers.
Anyway, not sure how accurate these folks' observations were, but its a potential starting point for anyone w/ some of the listed rollers. (Elite, InsideRide, Kreitler, SportCrafter, TruTrainer, ZZZing) Just on a sanity-check level, their readings for Kreitler poly-lites (3" drum) and SportCrafter ZROs (3.25" drum) are similar, so I take that as a good sign.
Based on their observations, the iBike trainer coefficients for the SportCrafters ZRO's in resistance settings 0 and 5 are:
setting 0
A=360
B=-41.83333333
C=2.1
D=-0.026666667
setting 5
A=480
B=-57.5
C=3.1
D=-0.04
