Keep it simple No indexing, to go out of whack , part of the DIY fix requirement.

FWIW I have a R'off hub, only need to add a tiny bit of oil in it every once in a while, the complicated parts were taken care of, shifting is just 2 cables
pulling in opposite directions. grip shifter is dead simple .

Co Motion US and Tout Terrain, German,imported, just a couple of the many builders of frames to optimize these hubs, for touring..

also available across the pond , Koga's signature program, bike build menu..

Koga not sold much in the US , somehow I found this one Used, an '04 factory build,
