INTERNALLY GEARED HUBS
     ======================

The following "pyjama sheet" tabulates available dimensional and gearing data for a number of gear-hub models. The list is far from complete, and I appreciate all corrections or additional information that can help fill in the gaps.

Only rear hubs are listed here, with or without brakes. Some front brake-hubs can be found in the "Regular hubs" (number) list, though.

The meaning of the abbrevations used under the heading "Brake-type" below are: C=Coaster, D=Drum, R="Roller".
