Aaron’s Bicycle Repair will redrill your Rohloff hub so you can lace up a 48 hole rear wheel. The service is low cost @ $50USD incl shipping back. Rohloff hubs only come in 32 hole drillings from the factory.
Keeping in mind that a 32H non-dished Rohloff wheel is stronger than a 48H dished wheel I’m not really sure how necessary this is. I’ve had 300lbs+ off cargo on my Big Dummy as well as my 165lbs with zero issues.
This will of course void your warranty!
