16 ritzel und 40 kettenblatt, ist der erfahrugn mit zwei kettenblätter wie zb. 40 - 48 kettenblätter kombination ?

On my MTB I am riding with 38/32 ///16 for a couple of years without any problems. 48/40///16 is within Ro`s recommended ratio range . So where is your doubt?
And the speedhub has its mechanical torque limiter with the nylon bolts, which protect the gears in worst case.
