What lacing for ISO 349 rim + Rohloff

First-time wheel builder here looking for expert advice. I'm building a ISO 349 wheel with a Rohloff Speedhub for a folding bike. I read somewhere that Rohloff hubs need a cross 2 pattern, but after getting the spokes I'm having trouble with the lacing. Does this combination need a cross 1 pattern? Any other advice you can offer?

If you are getting a severe angle at the nipple, yes.
How many spokes? Just curious.

32 spokes. It doesn’t seem to be so much of an angle/nipple problem as the latter spokes have to be bent in order to be installed around the earlier ones. It may just be my inexperience?

The smallest wheel I have ever built with a Rohloff was a 406 and that one required 1 x to get it right, so a 349 would definitely need to be 1x. I would not worry about interlacing them either. You can go all heads in or heads out with 1x but even if you chose to alternate heads in and out, I would not interlace.

It's going to depend on how the holes are drilled in the rim. When I've built small wheels, the spoke can end up kinked a little bit just above the spoke nipple. It looks a bit weird but the wheel held together fine.

The shortest spokes I ever used were on a 17" rim (Moulton size) with a Campy high-flange hub. I went with 1X lacing and it worked fine.

With 32 spokes, 16" rim, and a Rohloff hub that wheel is going to redefine "bombproof". I would build it 1X with all the bends on the inside of the flange. Putting the bends on the outside will kink the spoke around a little too much for my taste.

If you're feeling lucky you could lace it radial. I know, I know... people are going to say that it's going to "wind up". Not on that wheel- the spokes are going to be so short that the wheel will be essentially rigid.

Yup. 16" wheels with electric hub motors are laced radial all the time.
