Keep in mind old Shimano MTB cassettes use 10spd spacing. The M9100 12spd freehub driver fits onto existing DT Swiss hub shells.
Oops. You are correct. So it looks like only the 11-speed wheels are compatible with the 12-speed.

I just hope I can keep my Campy Boras when I upgrade to 12-speed.

shimano also released new 11sp mtb group (FH-M9125) to make even spoke tension:
microspline with 12sp = same body width, microspline with 11sp = narrow freehub body

I want to remove Di2 assembly from ST-R9170. Anyone knows what direction to unscrew this bolt? It rotates a bit in both directions and then stops. Both up/down paddles rotate around it, maybe some sort of preload or thread lock prevent removal?
