What is the widest range cassette sold? I imagine the new Eagle 11 - 50's must be in contention. So, if you had a reasonable underdrive at the low end, your monster mash gear could never be higher than 90"+. That wouldn't be enough for me on a 1/2 bike and I think tandems should have tractor trailer gearing and go from high teen's granny's to high 100 teen's spin down the 6% cool off the brakes top end. That simply isn't possible with 1x, and that is why I said that I think the o.p. does not speak for 'everyone'. 2x and even 3x have lots of life left in the 1/2 bike world. Decades more in the tandem and recumbent worlds.
