Yes Rohloff says:

To prevent overstraining the hub, a minimum sprocket ratio of 1.9 must be used. With the available sprockets these minumum possible sprocket ratios are:
chainring/sprocket: ~40/21, ~36/19, ~34/18, ~32/17, ~30/16, ~28/15, ~28/14, ~26/13 (ratio 1,9)
belt sprocket: 39/19, 39/20, 42/22, 46/24 (ratio 1,9).

This resembles a derailleur transmission of 20/40. Larger chainrings can be used without exceptions.

I decided the 34/18 would suit my needs best

Thanks for the link
