I probably view things a bit differently than some. My road bike as a triple and mountain bike as a double. My goal is to shift chainrings as little as possible.
I ride in 48 or 38 on my road bike and only use the 30 chainring when I really have to.
Mountain bike 34/24 and depending on the terrain, I’ll run in one or the other; mostly climbing 24, mostly flat or downhill 34.
I like my cassettes to be wide enough to let me stay in one ring as much as I can. This is not quite like having multiple 1x setups because I use fewer cogs
Years ago half step gearing was used with 5 speed freewheels, but 1x10, 11, 12 have eliminated the need.
