Thank You!
No, [**Knolly considers 56.5mm "optimal"**](https://knollybikes.com/pages/service-157trail-bb-crank) but recommends a 55-57mm chainline.
When the dust settles I would imagine we'll see the 'standard' as 55mm w/ a Super Boost 157mm rear end. I agree though, I think for anywhere with big hills/ tough climbs / pedal-and-plunge riding the setup on the Arrival with its 52mm chainline w/ 157 is nifty.
I'd prefer a narrower back end and looking at various suspension designs I don't really get what's so hard about a 49mm chainline with a 148 rear end. It's probably some aesthetic industrial-design factor I wouldn't understand - like internal brake routing.
