First off, sorry for asking about this on a thread for 5 speed hubs. I'll erase that post.
What are the actual, continuous duty, torque and rotational velocity ratings of the various Sturmey Archer 3 speed hubs? I've looked everywhere I can think of. Of course lots of "These are strong MF's", "NEVER use an IGH in a motorized build", and so on, in these and other fora, but nothing quantified. Say what you want about the NuVinci 171's (and yes, they are too heavy for non motorized bike builds), but they made this info available, and in it's proper context.
Thanks
