Right, but at this point I’m not sure which is which… At least in the data I’ve collected, you can view it both ways. Most of the hard efforts I do that might cause heat-drift are either in ERG mode in a low gear, or going up a steep hill, both of which also have a slow flywheel. So these conditions are themselves correlated.
I’ll try a flat TT some time this week (high power, fast flywheel) and see what happens. Another thing I want to try is pointing a fan at the KICKR’s flywheel to help it cool.
