I've spent enough time changing cassettes and cogs on my track bike, that I don't need to bolt on a different chain ring for a different ride. Just ain't gonna do that.
I get that 2x is dumb for your riding, but for other people it is really required.
You can get the same range from 1x, but not with small gear jump and the tight quick shifts I get from small gear jumps - 1x doesn't do both.
To be clear, I mean 2x wide range systems like compact doubles. Those don’t have small jumps between rear gears since they are typically using an 11-32 or 11-34 cassette. Traditional double road drivetrains have much closer ratios. They also lack the range of compact doubles.
