What Grease to use?

[Muzzarati]

Please elaborate on that statement.

 

Lithium grease is thinner and doesn't last as long. It apparently also damages seals, when used on your suspension.

 

I just play it safe and use the Teflon grease on everything, works well and lasts long.

I'm servicing my bike myself bought the tools should be here tommorow, just want to know what grease to use for the hubs bb etc, and for the disc brakes will Q20 work?

Put q20 on those brakes mate, and you'll find yourself a little more bos, Piet

We use the Motorex bike Grease 2000 - Seems to work great

 

*Edit* It is good at quieting the Avid brakes down...

breaks who needs breaks just throw them away make youre bike 500g lighter just use youre 5/10's as breaks ............

Agreed....You will ultimately BREAK something if you throw your BRAKES away

Yamalube blue waterproof grease - R68(last time I bought it) for a 500g tub at any Yamaha boat or bike dealership. Was recommended by my LBS and I have used it for the last 2yrs or so and really is a winner. Does noticeably repel water incursions in places like the lower headset bearing and BB bearings. I have used it all over my bike including greasing the Hope cassette freebody pawls/clicker/ratchet things.

 

Buy a 20ml/30ml syringe - fill it up with grease and now you have a very functional grease gun for filling bearings etc(remember to get a needle, just bust off the spiky needle part and use the plastic needle base bit as a cap to stop grease squeezing out when you are not using it)

I was thinking more in the line of personal experience. Not Google experience.

I have been using it on my bikes for more than 10 years without noticing any ill effects...

I am intrigued. What did you observe?

[Johan Bornman]

You need to use a grease that doesn't contain lithium preferably a Teflon based grease. Marine grease isn't great either, Q20 is possibly the worst thing you could do to your bike.

 

What I use... http://www.chainreac...lon/rp-prod5954

 

What's nice about this grease is you can use it for your suspension too.

How do you grease your suspension?

You again!

 

As I said before, try use non water resistant grease in wheel bearings of boat trailers that are submerged in water at the boat launch and see what happens or any bearings exposed to moisture in marine environments.

 

Water resistant grease is not a gimmick, it's a widely used industrial product esp in marine environments. Personally I have clearly noticed it does not get washed out or contaminated by water as easily as normal non water resistant greases.

 

If you plan on repacking your grease every time there's suspected water contamination then your idea of only using normal grease is good but I'm not that fastidious and rather just use water resistant grease, it works.

 

But I suppose I'm preaching to the choir from another church in this case

A choir from another church, you say. Funny.

 

Yes, it is me again.

 

Seriously now. You said you saw with your very eyes how this grease repelled the water. I want to know what this repelling action looked like. What did you observe?

 

Marine greases use calcium soaps rather than lithium soaps but that is just to prevent the salt in sea water reacting with the lithium soap. Soap here is not soap as in washing your face, but as the substrate of the grease.

 

Neither of these greases repel water. They can't. There is no mechanism for them to do it. Further, water contamination in any greased component that is agitated (like a wheel bearing) is bad news. The grease quickly forms an emulsion with the water ("waterproof" or not) and then the water is trapped, unable to evaporate but free to do its dirty work.

 

Waterproofing by way of grease is a misconception. "Waterproofing" a seal by smearing grease on is counterproductive since the grease quickly forms a tiny capillary along the shear line that actually sucks water in via a mechanism known as capillary action.

 

Please lets kill this waterproof grease myth for once and all.

 

Edit: I do like your needle tip tip though.

Is Squirt as lubricant waterproof then??

[Skylark]

I don't know about the composition of the greases but I am certain that the water- resistant grease does not emulsify as easily as normal grease. It's not wonder grease though, for that reason it's not called waterproof grease.

 

On boats if you use normal grease in certain areas you will have premature failure as a direct result of not using water-resistant grease, that is an undisputable fact. Same as with boat trailer wheel bearings.

Use Sunlight Liquid..... It is a soap and smells like lemons

JB, out of interest what did you study?

[Muzzarati]

How do you grease your suspension?

 

The way it tells you to in the Rock Shox Service manual.
