I love all of this experimentation, and the Rev folks sure do have a lot of experience.
For me, I am in the fixed gear or 1x8 or so camp. Fixed gear so pure and direct and connected. 1x8 more flexible, fewer problems on the hills, but not nearly as much easier as you would think considering there are eight times as many gears! I do have a city bike with IGH which is cleaner, but getting back to a derailed bike feels like a much more direct transfer of power. I would like a mechanical engineer/bike racer/someone who knows a lot to tell me: how much easier/faster is a geared bike than a single speed? With the terrain of Middle Tennessee (rolling hills) Is it 5% faster, like in a 1 hour race the geared bike wins by 3 minutes? 10% faster (wins by 6 minutes), or more like 1-2% faster (wins by a minute give or take)?
