To grease, or not to grease - Lubrication database.

I greased (very lightly) as I was getting creaking

Lubricating creaking parts attacks the symptom, not the disease. The creak will come back, and in the mean time the parts will have been wearing out where they are rubbing against one another.

lapping the mating surfaces together

Filth.

I cleaned both stem and bars anyway as I've cured a creak (on another bike) by doing this before. Also noticed the stem had a bit of metal protruding beside one of the threaded holes that takes a bolt from the faceplate, this looked like it has been rubbing the faceplate as there was shiny metal exposed on it do knocked that back with a file and abrasive paper.

So the grease may not have been what cured the creak.

Also, now my bars are quiet I noticed my cranks creak. Fuuuuu....

I've been told by a mechanic that copper slip is highly toxic (carcinogenic?) and is best avoided.

Think I'll stick to just grease.

From reading that, I infer, that if you are a fish or if you eat it, it is bad, but otherwise it is fairly harmless.

If anything in Copaslip is going to hurt you from skin contact, it's the grease rather than the copper particulate. Don't eat it, and don't wash it off into the local stream with sulphuric acid, as that won't do the fish any good.

Anyone wanna go in on this trade pack of boeshield T-9?

If someone has a source to buy it cheaper I'm all ears!

12oz cans from Boeshield direct are marginally cheaper per ounce if you buy two to get the free shipping.

4 pages? dafuq are you lot on about?

WD-40 ALL the things!

DIsc braks sqeelin? WD40!

Chain noisy? WD40!

Boyfriend/Girlfriend a bit whingy? WD40!

Midgets sqeelin? WD40!

Where do you spray it?

I'll PM you the photos.

You lube your chain with an aerosol?

No wonder you buy 12oz cans.

a bit whingy

Works on you?

Yesno: fuck Planet X.

If we bought two packs of this or this, we'd get free shipping from Boeshield (but then pay £4 to ship one to me/you).

Give it to the end of the day, to see if anyone else is interested?

I use a pot of Nimrod "seriously purple grease" that Condor sold me on pretty much every interface on the bike, except chain oil on the drivetrain. Nor stem / bars interface that I have never lubricated.

Any reason I should stop doing this?

Interesting about brake caliper frame bolts. I should get some locktite.

I didn't know you thought of our relationship in that way. Should we go exclusive?

Apple pie too dry!? wde40!

Yeah let me know if you wanna. Im hopefully working again next week so will be feeling rich enough to spend £30 on grease

ebb install - bb shell - to grease or not to grease?

Anti seize

Which of these types of grease, if any, would be recommended for headset bearings?

Multipurpose EP2 Lithium Grease

Moly Grease with Molybdenum Disulphide

Any of them will work fine, bicycles don't make high demands on grease and the headset is easily the least demanding part. I'd pick one of the ones with MoS₂, but you'd be hard pressed to see any actual difference in performance even in wheel bearings.
