Bad math.
If 96% efficient = 5.2 mph, then 90% efficient would be 4.875 mph, not 5.1 mph.
And that's with worst case efficiency numbers for the chain setup and best case
efficiency numbers for the IGH. Based on this, the other calculations are off
too.
Correct me if I'm wrong.

Mechanical inefficiency of the drivetrain is not the only thing that
makes a cyclist slower. Let's say, for example, that 90% of the total
inefficiency comes from tire rolling resistance and aerodynamics, and
10% comes from the mechanical friction and slop in the drivetrain.
Then the total effect o

You're right, of course. If you look at Berto's numbers, a drop from 5.2 to
5.1mph is a 2% decrease, not 6%. Obviously, other factors are involved in how
fast you go, not just the efficiency of the drivetrain.
Applied to my PBP example, going 2% slower would add about 1.7 hours to an

The "feel" issue is definitely a big issue with the Rohloff in certain
gears. You can feel static in the pedals as it grinds in gear 7, for
example. Hear it too. Makes you understand why some riders used to call them
pepper grinders and gives you the sensation of pedaling through water.

So far, I get the feeling that the internal gears on my Sturmey Archer 8S don't
like to be put under a load. It feels fine--just like a regular bike--when I'm
spinning on the flats. Going uphill, it feels harder to pedal than it did with
a fixed gear in the same ratio. In my experience, the I

I'm totally into riding slower (ask my friends), but I also do some "extreme"
rides where it could make a real difference to be even a little less efficient.

Mr. Berto's math is quite close.
Power varies with the cube of the speed (speed x speed x speed).
5.2 cubed / 5.1 cubed = 1.060 or about 6% difference in power

The power output says 1/8 hp and I assume that is a fixed value, and I
discounted aerodynamics and rolling resistance as well for such a small change
in speed. Beyond that, isn't it a simple linear relationship between drivetrain
efficiency and speed?

The specs of the frame and fork are what determine which brake caliper
you can use. The effective brake reach on Jim's Ram is 54mm, and
