Using Rohloff with a thicker chain I have a Bosch/Rohloff bike that currently uses a 3/32 chain. Seems like that's the standard for Rohloff hubs. Problem is, I'd much rather use a 3/16 chain, i.e. a chain that's exactly twice as thick. Are there Rohloff sprockets designed for this? And if not, how difficult is it to manufacture a 3/16-compatible Rohloff sprocket?

Update: even though I'm still sticking with 3/32 chains, I'm now using the stupidly thick (8.8mm pin length) Connect 7R8 chains.
This maybe late but KMC now manufacture a 1/2" X 1/8" splined sprocket for Rohloff hubs https://www.kmcchain.eu/webshop-sprocket

With a matching 1/8" chainring you can now use a 1/8" chain no problem.
