I doubt this is at all common outside the IGH world
even sounds odd to an IGH user..a Bike has 2 wheels..
in those hubs and how they work on the bike ..
You have to consider the Torque windup, on IGH.. it has to have a brace somewhere
to transfer that.
there is a special grip washer with Alfine.. it keeps the axle from rotating in the frame... .
Rohloff has a lot more torque to tame..
those have a few different ways to do that.
an arm under the chainstay [retrofit] or
OEM 1 dropouts .. torque transferred by a tab following the Axle into a longer vertical dropout,
or the OEM 2 a fork that fits over a Bolt head protruding inward
from the Lower of the 2 ISO pattern Disc Brake frame Mounts.
so you would have to pre plan your installations to match..
I have 2 OEM 1 hubs , but they are in 2 different sized wheels 20", 26"
