People that talk gear gaps on 1x are myopic. The only thing lost on a 1x is higher end stuff over 110 gear inches.
newb coming in strong with the heat!
I will just add that in the middle 8 or so cogs on my 2x11 gravel bike, the jumps are smaller than if I had a 1x11. Its sequential, unlike your claim, and its very much real.
I run 48/32 with 11-36. That gives a 121.19 - 24.74 gear inch range.
If I were to run 1x, I would need a 42t ring with an 11-46 cassette to get close to the same range as that would be a 106.18 - 25.29 gear inch range.
Below are by current 1170 cassette and a wide range cassette. Between the 2nd and 8th cog, there is a 13 tooth difference on my setup compared to a 19 tooth difference on the 1x setup. Linear progression and tighter jumps for the 2x.
my current cassette- 11,12,13,15,17,19,22,25,28,32,36
an available wide range cassette- 11,13,15,18,21,24,28,32,36,40,46
ETA- When my current cassette finally dies, I will most likely buy an 11-34. The cassette range will be even tighter for sequential shifting.
