To add some clarification to the chain recommendation for Rene Herse cranks:
11-speed rings (also suitable for 9- and 10-speed): Ramps and pins have to be designed for one specific chain, and we designed ours for the 11-speed Ultegra chain. So the shifting is best with this chain. Other chains should work, but may not shift quite as smoothly. 5-10-speed rings, 10-speed: There are some 10-speed chains that have a propensity for chain suck. We've done a lot of testing with Ultegra chains, and they work great. So that is our recommendation, but others may work well, too. Just avoid chains that are known for chain suck... 5-10-speed rings, 5-9-speed: Use any chain you want. I run SRAM 8-speed chains on my Herse (5-speed), Urban Bike (6-speed) and Mule (7-speed), with no problems whatsoever.
