26" rim, Nexus 4 36H IGH: X3 or X4 lacing?

X4 is stronger, but as this hub is high flange and the rim a 26", spokes could overlap...
I don't want to buy 2 spoke sets. Anyone has experience on this? Thanks!

The differences in strength between 3x and 4x are tiny. Go 3x, if only to make replacing a broken spoke that much easier. With symmetrical flanges, a 26" rim, and 36 spokes, this wheel will be strong enough for a dump truck.

And a high flange hub in a 26" wheel can cause the spokes to sit at an angle where they meet the rim, causing a bend right where they exit the nipple. I had to rebuild a wheel b/c of that, too many broken spokes.
YMMV though due to flange height, spoke count, and the amount of "swivel" available in the nipple seat.

Lacing a large flange Nexus hub 4x will create a very acute spoke/rim. The spoke nipple may not be able to pivot enough in its socket to match the natural spoke line. This puts a lot of stress on the spoke and nipple.
edit-posted this before reading dabac's post. His info is correct.
I have a 36h Nexus laced 3x on a 700c wheel and the spoke angle is about at the limit I'd be comfortable with.
3x built right on a good quality rim will be plenty strong enough.

I have a 36H 26" rim with an Alfine hub, I started with 3x but didn't like the spoke angle at the rim, I changed to 2x, much better angle. I'd never consider 4x on a 36H/28" wheel due to the spoke angle and overlap.

Rim is a Weinmann ZAC 19. Do you think X2 would be strong enough? Intended use is as a commuter, occasionally with a trailer, and my weight is 70 kg.

Even 2X should be plenty strong enough. You aren't that heavy (155 pounds in American money) and a trailer doesn't put much additional weight directly on the rear wheel.

Only issue a 2 cross could have is, like, after hammering the wheel on rough unpaved roads
long enough, with a heavy load, the spoke could tear out a section of aluminum hub-shell.

By definition that is some unusually rather heavy use..

4 cross is pulling across the hub-flange to the opposite side..

3X is bordeline.

If you do start breaking spokes right where the enter the nipple barrel - resize and re-lace at 2X.
