Anti seize compound

[Dirtbreath]

How long does this seizing take? Are we talking a few rides or months without removing the seatpost. I remove my post and wipe down every couple of bike washes and never had problems.

First-hand and repeated experience like this is useful. I'll give you my interpretation and tell me if my assumptions are right.

 

1) The interface is rigid and doesn't "pump" water. You don't say if you apply the coppaslip to bolts or two other interfaces. I assume whatever it is' date=' they remain fixed against each other and don't move. In contrast, a seatpost is a dynamic joint. It is clamped at the top only and sitting, pedalling and road bumps cause the unclamped part to move in the seat tube and mix the grease and water into an emulsion.

 

My guess is that your interface doesn't do that and even if there is water intrusion it never turns the compound into an emulsion.  Just a guess.

 

2) Secondly, I guess that these components are robust and can take a bit of force when disassembling. Not much, but more than the shear strength of the copper.

 

The fact is that seatposts are problematic whether you apply compound or not and I am leaning towards a dry fit for the reasons explained above.

1)Yes, its basically a steel tube thats internally threaded on either end, an aluminium threaded end cap (male) with an o-ring then simply screws down to seal the tube.

The seperated water is released by taps. As the trap can hold anything from 100 -500 ml or more of water and is pressurised by air we often find the water has been forced (leaked) down into the threads (prevented from escaping by the o-ring) where it lies and causes heavy corrosion, without coppaslip the corrosion just makes it almost impossible to seperate the two after a few months.  

 

As you mention there is no movement, its all very static.

 

2)Yah, as its aluminium and I have seen a few threads just peel off due to the corrosion, one has to be a bit carefull, but generally one can apply a fair amount of pressure.

Certainly a lot more than I would feel comfortable with applying to a seat post.

 

Makes sense mate, thanks.

As do I bud but the bike in question had not been used for about 2-3 months......

I wish I knew the answer that one. All I know is that I always leave it too long and then it is stuck. Whether it got stuck a week after my last "service" or one second before I tried to get it off I can't say.

 

 

I don't think time per se is a factor but a combination of washing/wet riding, weight, riding style and the tightness of the "seal" at the seat post collar.

Lots of people confuse the role of so-called carbon compound with anti-seize compound. The two is not the same. Carbon compound is a friction compound or simply put, grease with grit. It prevents sliding. Copper compound prevents friction welding of dry bold/nut interfaces.

Lot's of people maybe, but not ALL the people, please stop making assumptions.
