I want to put an electric motor on a fully-loaded touring bicycle to run on gravel and off-road. I weigh 217 pounds so I am looking for the strongest wheel I can build. I am trying to decide between a DT Swiss 36h sleeved rim and a DT Swiss 32h welded rim. Which matters more, four additional spokes or a welded joint? I want to build the rear wheel on a Rohloff hub which limits my choices to 32h and 36h. So 32h welded or 36h sleeved?
