      Rich,

      I just found Shimano's recommendation for ratio.  It is (at least for a Nexus SG-8R31), in their technical document.  It does mot explicitly warn against very low ratios, but do we assume that is what they mean?

      http://www.shimano.com.au/media/techdocs/content/cycle/SI/Nexus/InternalHub/SG8R31_36/37J0A-001_SG-8R31_36-EN_v1_m56577569830638076.pdf


      Long link, so just google "Shimano Nexus SG-8R31."    To quote Shimano:

      "It is recommended that you set the chainrings so that the gear ratios are 

      approximately 2.1. 

      Example: F36T – R16T, F38T – R18T, F46T – R22T"
