How about 1x12 for my road bike? 10-12-14-15-16-17-18-20-23-27-32-40 with a 42t chainring, preferably 110 and 130bcd chainring standards so stupid-light cranks still work. electronic shift availability desired so I can shift from the aero or the drops. At 61 I need near 1:1 just to get up my driveway, which I used to do in 50-18 fixed. And I need aero so I can still average 19mph to work on the best days. Look at the desired cogs; the 42-16 is what you would use for 19-20 mph, right in the middle of the close ratio. I have a rohloff, bought 15 years ago; the bottom 7 gears are joyless riding and life is much better when the bike is a joy to ride. Yes I know proper shifting technology started on the mountain and progressed to the road. Let it happen again.
