I just recently purchased an LX M580 crank with external bearings. I happened on to Park tool’s web site and they mentioned preparing the frame by “Facing” the bottom bracket before mounting the bottom bracket.
My question is, is this necessary? Does anyone have any information on this? My bike is about two years old.
Thanks!
