Good idea or bad?

Is it a good or bad idea to put Litium grease (multi purpose) on the seatpost that will go into a steel frame? Will it rust or will it protect it from rusting? Thanx for the help guys

It's a *good* idea. In general, it's a good idea to put grease or anti-seize compound *anywhere* that steel and aluminum will be pressed up against each other. This prevents corrosion that can cause a stuck seatpost or stem.

I use white lithium grease with good results, and others prefer marine wheel bearing grease.

lithium grease gets hard and tacky with age, i would recommend any other kind of grease. i prefer lanolube, which is basically sheep's hair grease. it has excellent anti seize and greasing properties, i use it in my headset bearings and bb bearings as well, to no ill effects.

White lithium grease works fine for fasteners and seatposts. Like moxfyre, I've been happy with the results. I wouldn't use it for bearings, though.

Never happen. This is the third thread currently on the Forum discussing this particular topic and nothing is ever decided after pages and pages of mis-information and acrimonious debate.

The only other topics that produce the same amount of noise are:1) the "best" chain lube and 2) Shimano vs Campy.

Enjoy!

But you know what? I do enjoy these threads! Because there's always some angle or aspect that I hadn't heard before. Last year, these grease threads got me to devote a the better part of a day to doing research on the web, and I learned so much about how grease is made, how it's tested, what the different emulsions do, and all that research informed my own decision about what I use. The same is true of bike chain lube. By continually having these issues come up and get discussed, there's new information that comes out and new things to consider. It would be nice if there were just one "best" lube, but everyone's circumstances are different. So the discussion is valuable.

How *is* grease made, do you mind sharing the link?

I just found out that the high-vacuum lubricant we use to seal bell jars in our lab is made from... wait for it... GOOSE FAT!

Metal to metal is never a good idea when the two tend to stay in one place for long periods of time. A seat post is definitely vulnerable as it tends to also collect human sweat from the rider. And humand sweat is brutal in it's ability to create corrosion. Grease or antiseize of any kind is better than a seized seat post from a dry insertion.

Infidels! Whale-murderers! Verily, we shall lube our chains with the blood of our enemies.

Those poor geese.

I don't mind at all sharing the links, I will try to unearth them from my vast bookmark file. There are a bunch of them. I looked at industrial standards, testing parameters, chemical composition, it's fascinating. I'll cut to the chase and tell you my conclusion though. Lubrimatic Marine Wheelbearing Grease from Home Depot. It's a calcium-sulfonate based grease, and the base material is a large factor in determining how a grease holds up over time and when in use and under assault--if it separates, or degrades, or not. And calcium sulfonate is *surprisingly* comparable to Park's highly rated (and high-priced) polyurea-based grease, Park Poly-lube. I've been using Lubrimatic in nearly every moving part of all six of our bikes, at every overhaul for the last two years, and it maintains its consistency like a champ. Really stays put, better than Phil Grease in my experience. I like that the Lubrimatic is so good and so cheap, and so readily available--that way, I never hesitate to use a lot of it, very frequently. Which is of course the other part of the equation. Frequent overhauls make your races very very happy.

Just thought of something that hasn't been mentioned in this thread yet. If you ever switch from one type of grease to another, be sure to remove all traces of the old grease, because greases with different compositions do not mix well. They may liquify or separate, or they might harden--some weird things can happen. Very few are compatible with other types. Somewhere I have a chart about that too. I'll have to look.

Am I the only one in the world whose Home Depot doesn't sell Lubrimatic Marine Wheel Bearing Grease??? Either that or the incompetent employees don't know where to put it on the shelves. Mine has white lithium, which works well for me, but since everyone else swears by the marine stuff I'm starting to get jealous...

Wow, that's something. In my local Home Depot, the Lubrimatic is right next to the white lithium grease.

Okay, for all you grease-aholics, here are some links for more information about grease than you ever thought you'd want to know. Some of these are a couple years old, so try a fresh Google search if you want even more information. Please note, most of these are not specifically about *bicycle* grease, but they discuss all the types of greases that we typically use on our bikes.
