Inner roller width of a chain is about 2.4 mm. So guess it doesn't miss enough to really bother shifting, though it's not a perfect match.
Wow, thats really interesting and something I didnt look into when selecting components for the build. I dumb lucked into it working!
It was a kludge job(albeit a nicely spec'd one) to begin with since I was looking to use 105 components and a large cassette to get better bailout gearing. At least it lucked into working.
edited- I did some reading, and it looks like the SRAM cassette I have is a road cassette, even though the gearing range is wide.

SRAM recommends, on their site, using it with the Rival 22 group which is a road group. That would explain why it works well with my 105 5800 setup.
