Which grease do you use for preventing water/ grime ingress into Bottom Bracket?

Normally I would use Philwood waterproof grease but I have always wondered what others here use. I am thinking more along the lines of hollow spindle bottom brackets, GXP, BB30, ETC. where the bearings can become contaminated quite easily. I have used Pedros SYN grease but it seems like it is a little loose and has a tendency to take on contaminants pretty readily.

The grease that we use at the shop is the Park Polylube that comes in the large tub. It gets the job done and i dont have many complaints at all.
I personally have really liked Phil Wood grease. It is costly so i have a tub of generic grease for bolts and such to save the Phil Wood for vital areas.
If You would like to try some out then buy a different brand after you finish a tube and make notes on their performance as you go through them.
That is what i do with most lubricants and cleaners.
Goodluck

Well external bearing types are out there in the crud stream
so Prevent any contamination is an un worldly expectation.

I have found I get no contamination on my 2 bikes with campag race triples
and their short 111square taper BB's because I slipped on an O ring over the spindle,
before I put on the crank arms .. the arm presses the O ring
against the BB cup opening.

and I ride other bikes in foul weather , the one I use most I dug out a GreaseGuard
BB and will use it. they use a needle tip grease gun, to to Push clean grease behind the bearings.
forcing out the contaminated stuff.

got a clever Idea to cover the external bearing assemblies to keep the dirt outside?

I use commercial marine grade grease intended for things that get submerged like boat trailers. The other product I've had success with is Lubriplate 630aa which is a white lithium based grease that gives me good service, but is softer and seems to offer less viscous drag than my marine stuff.

+1 ......and you can buy a small tub that will last pretty much forever for the same $ of a much smaller tube of Phil or other bicycle hyped/marketed grease.

As far as that, boat trailer wheel bearing grease was the MTB choice in the 80's..

but contamination, like poo.. it happens..

Correct. You can also buy Phils in 14-oz grease gun cartridges or a 22 oz tub at much lower cost per oz than the little tubes so that makes it more competative. It remains more expensive then the generic greases but the penalty is much less.

As far as I can tell, Phil grease is just a standard marine-grade grease with a "Phil" label on the container.

I use Phil's and have also used boat trailer bearing grease and cannot tell the difference.

Reduces the premium to just four or five times what the same grease costs with the original manufacturer's label on it. And, of course, Phil, Park et al dont' publish specs for their lubricants, so you can't tell if they decide to buy something else from some else.

I use the heaviest auto wheel bearing grease I can find.

Call or email them and request the MSDS sheet.

True, and if I were running a high volume repair shop the cost penalty might be something to consider. But, for my few bikes and their annual overhauls, the cost of grease gets lost in the round-off error. That 22-oz tub will last 5 years or more, probably much more.
