Grease is composed of oil (synthetic or mineral), thickener, and additives. For bike wheel bearings a I think a moderate viscosity oil (around ISO 100) with a calcium sulfonate thickener (for rust prevention in the wet) would be a good choice.

I think some better boat trailer wheel greases may fit this or you could just buy something that says it's for bike wheel bearings, like Phil Woods.

Yes, I'm aware of the chemistry and composition of greases but, my point is, that the exotics are overkill for bicycle applications. The simplest stuff available is plenty good unless you are extremely negligent.

That said, unless you are maintaining a fleet of dozens of bikes, you use so little grease that even the most expensive stuff isn't a budget breaker.

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.

There is a lot of wisdom embedded in this HillRider post.

An excellent grease for bearings, widely available at Home Depot and other stores for around $4/tub, is Lubritech's "Marine Corrosion Control and Trailer Wheel Bearing Grease"; for a dollar or two extra, you can also pick up some "flux brushes" to apply the grease.

PS - Here's a not so cheap link that includes a photo of the tub: http://www.etrailer.com/p-l11404.htm

What purpose does applying with the flux brushes serve?

I just **** the grease onto the cones and bearings with my fingers.

Of course, it means I have to wash my hands with dish soap to get it off.

Am I missing something fancy? Are flux brushes the thing to use for grease?

Lotsa good advice/answers - unless of course it's a coaster brake hub you're repacking. In that case, use a high temperature rated grease.
