Any help would be most appreciated, thanks mike anderson While the Barium grease you mention looks good, might it be 'overkill' for such a light application as bicycle wheels? Do bike wheel bearings need a high speed, high load grease? Not from what I've learned. Most modern wheels that use open bearing from Campy and Shimano are pretty well protected from water intrusion and if you re-pack the bearings at the end of each season (summer and winter) all will be fine. Lithium grease for bike wheel bearings has been used for what seems eons, worked well, and is cheap. If you desire something a little heavier, regular automotive wheel bearing grease would fill the bill, also very cheap.

Barium grease?

Any help would be most appreciated, thanks mike anderson I can't help on the barium grease, but let me recommend Versilube, G322L, a silicone lubricating grease. I recently took apart some bottom brackets on which I had used Versilube, about 1975. The grease was only slightly darkened (it's pale yellow), and as far as I can see the cups and balls were in good shape. I's still available -- check the web. -- Bob Wheeler --- http://www.bobwheeler.com/ ECHIP, Inc. --- Randomness comes in bunches.

Bicycle applications make extremely light demands on greases. Almost anything will work for you here. I don't see anything that would recommend a barium grease over any other grease. For more information about greases, I just found this site: http://www.reliability.com/articles/article66.htm Grease is very poorly understood by the public. There's very little about it that is magic, and spending lots of money for most specialty greases is a total waste. The only things we need to worry about are its tolerance to water and ability to inhibit corrosion. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA -----------------------------------------------

It sure makes the cheap, plentiful and very available lithium grease look good, doesn't it?
