I'm replacing the NX cranks on my bike with X01 cranks, all of the install videos I've seen show people greasing the cranks but these look like they're pre-greased. There's blue/green stuff on the spindle and brown inside the socket on the crank as per the pictures.
Is this grease and is this sufficient? Should remove it and replace it with this grease I have? My old spindle didn't seem to have very much grease at all and it was black so difficult to compare.
