Just a note that not all cartridge BB's are the same in terms of the stated need for grease during installation. According to the installation instructions, Phil BB retaining rings and the bottom bracket shell should not get greased. Phil supplies a threadlock liquid (Loctite blue?) with instructions to use that on the retaining rings - not grease. I was initially uncomfortable with this and I had to suspend my disbelief while following the instructions.
My experience thus far with my two Phil equipped bikes (two years, heavy loads, and lots of miles) has shown that this non-greased fitting works noiselessly. That said, and Phil's instructions notwithstanding, I'm open to what others have experienced. Any noisy Phil BB's that were remedied by greasing the threads? Any problems experienced due to greasing?
