That would be a Rohloff "Speedhub"
(https://www.rohloff.de/en/products/speedhub/ ) I think the
general consensus is that there's some energy loss compared to a
derailleur-based drivetrain because of all the little planetary
gears and oil bath. It's a really nice piece of engineering, and in
some applications the losses are tolerable.


Seems to me to be just the thing for a touring bike in areas of
inclement weather. As well as a chain guard and fenders.


My use of the Rohloff is a "low-maintenance commuter bike". I oil the
chain on my recumbent once or twice a year and replace the chain once
every five years or so.

Changing the oil bath of my Rohloff first time after some 5 years did
give me a massive speed boost, like pumping up the tires from 20 to 80
psi (I should have changed that oil a lot earlier).
