In general, bicycle bearings have a very easy life. They run at very low rpm, temperature and load compared to most industrial and automotive bearings. So the choice of grease is pretty undemanding and almost anything will do adequately.

Super high-performance greases are a waste of money and the very fibrous automotive wheel bearing greases are certainly functional but unnecessarily heavy bodied. Regular white lithium grease will work fine if you do any kind of routine maintenance, like an annual overhaul.

The "bicycle specific" greases are just repackaged industrial products but do work well. I buy Phil Grease in either a 14-oz cylinder or a 22-oz tub which is much more cost effective than the 3-oz squeeze tubes.

I also bought a Duelco refillable grease gun (http://www.biketoolsetc.com/index.cg...item_id=DU-LG1 ) and fill it with the Phil Grease. It meters the grease accurately, reduces waste and keeps the grease in the bulk container clean.
