Yes you can but I dont see any real advantage to switching to 30mm axles and paying rotor £40 odd for BB .. I am using a £12 Ultegra 6700 BB with Rotor 3D
I've been unsure of this, does a P2M for Rotor 3DF/Plus definitely fit on the regular cheapo Rotor 3D cranks? That'll save me a few pennies in the future if so.
@Hovis - although you can replace the gxp BB with a rotor BSA30 one and run the 3d+ /3DF 30mm axle in a bsa 68mm threaded bb
