Still, there are zero-cross, zero-angle rear wheels out there, presumably used in applications where the strength of the build might have been inadequate for bikes with motors and/or disc brakes.
No, I didn't mean spiral on one side, and opposite spiral on the other side. I meant trailing and leading spokes on both sides, just not crossing. I see this most frequently with very large hubs (like a hub motor), most especially with smaller wheels (like 20"/406, and even 16"), where crossing the spokes would be extremely difficult and bad, *with low spoke numbers*, the spokes would meet the rim at a bad angle (assuming rims not dimpled, aimed and drilled). I *think* that 1X patterns are possible with higher spoke numbers, as the angles aren't as bad. But again, the crossing is not essential, just some trailing and leading angle to the spokes, and I've sometimes seen this, same side, 0X. It doesn't take that much angle to transmit torque, especially with a very large diameter hub, there's more leverage at the flange holes.
