Does anyone know offhand what the SA AW gear tooth profile is?... I mean the gears inside the hub, are they Module or DP (basically metric or imperial) and does anyone know what the actual dimensions of the ring gear are.... I need to build a planetary gear speed increaser, and the Sturmey hubs are so cheap secondhand that they might be a good place to start.
