Not sure if this is the correct thread, but i just put together this 3 speed. Sturmey Archer SRF3 free wheel. Geometry is tight, fast. I like the 3 speed internal a lot and actually want build up another one.

Does anyone know if the Sturmey Archer SRF3 can be installed on a frame with vertical dropouts? Does it have to be level like the shimano alfine using the anti turn washers? Can it be put in a vertical position and still work. I understand it would have to run some kind of chain tension/derailleur setup.
