Great call, Just sent Brian an email about it. He's also running the road VBC cranks like the Hunq on the Radavist. Very curious how that works.
Last night I bought a super cheap 127.5mm BB just to try it out. Turns out it does work, despite the White Ind calculations pointing me to a much longer spindle length. I have about 3-4mm clearance at the chainring bolts, which would be the first thing to contact the frame. That suggests I could get away with a shorter spindle, maybe a 125, which still seems very long to me, but so it goes. I'll update when it's finally resolved!
