Race Face Aeffect 165mm cranks and 30T chainring from the parts bin.
ZTTO cassette is crazy light and shifts amazingly.
Weight has gone up by 200g due to the heavier (but shorter) 165mm cranks. BB is still super low though so I might even look into 155mm cranks if I want to keep the mullet setup (will have to see how these go with the extra 5mm clearance).
