Being primarily a user of Shimano bottom brackets and cranks, I'm curious (in the spirit of friendly discussion, not argument, of course) where their guidance as to dry or greased can be found. My UN55 bottom brackets generally have a film of grease on the tapers that I figure is leftover from manufacturing or placed on for shipping. The included instructions don't say anything about stripping them to dry metal, so I haven't been. I haven't seen anything in the techdocs, either. Thanks.
