But the food tastes so much better when you rode your Rohloff bike to the grocery store. <Insert chuckle here.>

To the best of my knowledge Rohloff does not have a torque limit but they do have a limit on the ratio of chainring to rear sprocket, riders under 100 kg that ratio is 1.9, heavier rider and tandems have a higher ratio but I am not sure what that currently is. Although setting a ratio like that is a form of torque limiting, it is much less precise than the specification you cited for the pinion.

For touring with a load I use a chainring with a 2.25 ratio. The 2.25 ratio gives me a first gear that has a cadence of 72 at 3.5 mph with a 57mm wide 26 inch tire. I need 3.5 mph to maintain vertical and directional stability, so a lower gear would be lower than I would find useful. For unladen riding around home I change that to 2.75 ratio as I find an unloaded bike does not need the lowest gears for the hills near my home.

I'd pick this Siskiyou with Rohloff hub, less-rack-mount-interfering chainstay brake caliper mount and eccentric BB.

CoMo offers the Pathfinder Package as a $600 option on all it's bike, consisting of a Schmidt SON28 hub, Edelux II headlight and Sinewave Cycles Reactor USB steerer cap. That is a good lighting/charging package but it's twice what you or I would pay for the parts from a German LBS (which is the case for every component or option on a CoMo bike).....
I considered the Pangea and Thorn Nomad Mk II which is what I eventually got. Both are 26 inch. I think that 26 inch wheels make a bit more sense for an S&S bike than a 650b wheel as they are a bit smaller diameter and fit better in the case. But the 650b beats the 700c wheel in this regard, so maybe the choice of 650b was a compromise.

I found that the Sinewave does not play well with my Garmin 64, the Sinewave lacks a cache battery that my Garmin appears to require. To make my Garmin 64 work with the Sinewave, I need an external cache battery. Perhaps the other Garmin models work with the Sinewave directly, but not my Garmin 64. My Garmin 64 also works great with the B&M Luxox U because it has a cache battery built in.
