DUB had to work on older and less progressive* threaded frames too, and squishing a 30mm axle in those is a bit of a ballache. So they dropped 1.1mm to make it easier :)

386Evo goes in 1.37"×68mm threaded shells, it's just like a big bore HT2/GXP/UT. There's plenty of room in the shell for a 30mm axle if you have outboard bearings.
