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".
