Grease & paste

[livpoksoc]

I'm swapping my stem this weekend & on a youtube video, it recommended using anti-seize paste & grease on the bolts.

Can anyone recommend something or point out if there's any that aren't suitable for certain bikes etc?

You don't need it. Regular grease is enough ! If parts are carbon, it's sometimes recommended to use assembly paste on the seatpin as it reduces the need to torque it up. I've used grease on my carbon seatpin into an alloy frame - mainly to reduce any galvanic corrosion/bonding. It doesn't slip.

That should be an 'or' not an '&'
Steel bolt into aluminium stem, I tend to use this stuff, but only because I have it, and a 20g stick last for ages.
Regular grease will be just as good to be honest.

I do use an assembly paste on all things carbon though, because I have a mortal fear of delamination caused by overtorqueing.

All my bikes (and there are 12 in the garage) have used nothing more than Vaseline. They're all in good order.

My family are the cause of it!

Me - 4
Mrs - 5
sprog 1 -1
sprog 2 - 1
sprog 3 - 5
sprog 4 - 2
+ at least two frames not currently built up
and sprogs 1 & 2 each have a bike at uni.

I am a great believer in the right thing for the right job. Coppaslip on pedal threads and bolts where you're threading alloy into steel or vice versa, like steel bolts into alloy stem clamps and so on. . Ordinary grease on stuff that needs to be waterproof and lubricated like headsets, BB cups and of course I keep a tub of marine grease to re-pack bearings. I also have a tube of carbon assembly paste for carbon bars in alloy stem clamps, and for fitting my Reverb seatposts into all of the MTBs. The seatpost stops working if you clamp it too tightly, so the plastic grit in the paste means grip without massive torque. Finally loctite on things that could vibrate loose like brake rotor bolts and brake caliper fitting bolts. If you're doing a lot of bike maintenance then a small grease gun and tube grease is a godsend.

... and I'm a great believer in Vaseline, nothing more, nothing less and it works. It has other uses as well ... which is nice ....

Not sure about the 'other uses' but PETROLEUM JELLY is better than grease as an anti-seize compound but not so good as a lube. Over to you @fnarr.

Vaseline works fine in all my bike lube applications ...

As I have stated before - using anti seize - assembly grease - any grease and also Vaseline will change the Coefficient of Friction - therefore changing the Torque values. All Torques stated are for dry threads and dry conditions - allowances have to be made for the different lubrication added - and tightening torques will usually be reduced - if tightened to the stated torque with any lubrication the torque will be much greater.

Well I don't know much about torques, but I've never had anything come undone on the bike after tightening it, or broken anything by over-tightening either. All my bikes is made of metal though. In 40 years of fettling have never needed a torque wrench or needed to adjust my 'feel' for different types of grease (though maybe 'cos I only use the one type).
Am I missing out?

I always lube with some variation of Loctite or light oil before torque. Depends on if I want the part to come apart.

I know this may not be correct but old habits.
