Squeaking seat post

[Tractor]

A quick search didn't turn up anything so if this has been covered elsewhere please point me in the right direction.

 

I have an aluminium seat post mounted to an aluminium frame and it's squeaking, need to know what "grease" the bike shops use on the posts. Is it just good old fashioned wheel bearing grease or is there a specific compound that I should be using?

It's more likely the actual seat. Take your seat apart clean the bolts with oil and then dry them with a rag.. Spray some oil in the parts that connect the al holders to the actual seat and then put it back together.. Worked for me... Oh and tighten it up nicely..I also wiped the post down with an oil rag for good measure

What he said. Same issue with me, but once i spray the bolts (where it connects to seat) with Q20 it disappears. And believe me i checked everything beforehand....

Take it out, clean the seatpost, clamp and insertion in the frame. Then grease with normal bearing grease, I use castrol, a tub cost me 50 bucks. I had the same issue and now been squeak free for many a mile.

I use normal bearing grease on the post and the where the rails go into the saddle clamp.

 

Use it sparingly as too much will attract dirt and the squeaking will be worse.

Excellent, thanks gents

Copper slip is the best for something like that. I live in Durban and ride an aluminium cannondale with an aluminium seatpost, I only ever use copper slip. It doesn't go "waxy" Like grease does. Best to use it on all screws,bolts, pedals, etc. That way you will never have an issue with a corroded thread.

I think the compound you are talking about is what shops use on carbon bikes. It's fairly thin and gritty, the "grit" stops the carbon from slipping and creaking. That probably won't work the best for your problem and will cost quite a bit more.

Careful not to over tighten the seat post clamp as well,it will also cause it to creak

Remember, a THIN layer of grease or copper slip (whatever you choose to use).

You just need to have a lubricating layer on the surface.

 

Hope you get sorted soon
