I thought the point of NW was so the chainring didn't throw the chain so easily.

What's the point of having it on jockey wheels which are surrounded by a cage?

I don't know. The Shimano pulleys don't have narrow/wide profiling, that I can see:

And the SRAM 12/14T pulleys from Kogel (which matches what the mech ships with) have a narrow/wide profile on the lower pulley, so I'm assuming that the reason they specified the 14/14T set was that they didn't have it.

But @TotalShanner had no issues with his Shimano HG+ chain on the lower pulley wheel, so who knows?

Well you've opened and fitted the pulleys so does that mean you can't send them back now anyway?

Give it a try with the sram pulleys first. I'd be interested to see if you get on OK. I can send you a video of what mine look like while pedaling if you want. Really no issues.

The comments in that article are the only ones I've really seen saying they had issues with the pulleys. But there's not really a great deal of info out there on what is obviously a niche set up.
