We fucked up the threads in the drive side, 'cause I wasn't patient enough. The BB was stuck and the fixed cup was NDS. I assumed the BB was threaded in from the wrong side, which it turned out it wasn't. I made Mads fuck up the DS thread with a hole saw instead of sorting the fixed cup side first, which in hindsight was really stupid, but such is life. I'll give it a non-threaded BB and that'll probably work fine.
