Please allow the user to more accurately model the virtual gear combinations they actually ride outdoors. I have no idea what measure of change to expect when shifting virtual gears, causing me to do multiple shifts. If it is a % of the actual chainring/rear cog tooth ratio (or crank rpm vs. trainer axle rpm), then please present a line in the "number of gears" selection page that lists the equivalent gear-inches for a user-selected wheel-tire size (i.e. 700c or 29er, etc). I could then select what rear cog size I want to get a desired gear-inch range. Let me ride (or nearly) what I ride outside.
