Replace a 7710 bottom bracket with 9100 or Rotor BB1

Replace a 7710 bottom bracket with 9100 or Rotor BB1

Hi, I have a 2010 “Fuji Track Elite Euro” and I have a “NGeco Rotor ALDHU R 24mm Track with cranks” power meter. The current bottom bracket is a BB7710 which isn't compatible with the cranks on this power meter. Is it likely that a new Dura Ace 9100 would fit? When I run through the configurator on the power2max website it comes up with a Rotor BB1 BSA English thread 68MM, would that be a safer bet? Thanks for any advice.
