I’m not sure about you but I don’t think I’d be able to tell the difference between 2.73 & 2.77 which on a 29er are 79.17 and 80.33 gear inches so really there’s one extra gear at the top end.
Is my maths dodgy or have you missed out the top end 36T ring of 94.8”?
I think that proves that a “simple” choose the next largest gear, well, isn’t simple and you’d be hard pushed to remember all that just to get to a gear that is a couple of percent harder/easier than the one you are in.
I’ve spent 25 years riding with 2x and 3x, I have got the hang of it by now.
I dunno where you get 11-36 from, Shimano MTB 11sp cassettes are 40, 42 or 46 I think.
@idlejohn -I wasn’t comparing the two top ratios but the top of the 1×11 with the next to top of the 2×10 which is very close. The top ratio of the 2×10 is, as you say, 94.8 It’s still only one extra ratio though.
@molgrips – 2×10 not 11. So you do five shifts just to move up by a couple of % difference? What I’m saying is that you aren’t moving to the real next harder/easier gear but the one which is convenient, i.e. changing the front ring and one shift at the rear isn’t moving to the next gear so saying that 1x has big jumps (which it may have) is irrelevant because you aren’t making small jumps with which to compare.

Why would you compare the small chainring/small cog ratio on a 2x when nobody uses that combination?
I wasn’t comparing the 22/11 with anything. I compared the 22/36 and the 30/42 at one end and the 30/11 and both the 36/13 and 36/11 at the other end. I noted the 22/11 as part of the overall sequence because if I hadn’t some bright* spark would say I hadn’t covered the entire set of combinations!
I wrote:
At the top end on the 1x 30/11 gives a ratio of 2.73, the 2x has ratios of 2.77 and 3.27 better than that.
At the bottom end the 1x has 30/42 = 0.71 whereas the 2x has 0.69 and 0.61 lower.
9 speed cassettes are half the price of 11 speed for the same range. That 46t ring must be made from unicorn horn.
more weight, yes, but lowers centre of gravity.
weighs less than a dropper.
Disadvantages – death throes were a shotgun approach to standards. My Pitch is supposedly a shimano E2 mount but the holes are clearly for a Sram S1 mount. Direct mount being in name only as you need an adaptor for anything else.
