Slippery seatpost woes

Post by AlistairJ » Fri Sep 14, 2007 09:12

Hi all,

Just started with this MTB lark - bought a Trek hardtail.

It said in the manual that its important to grease the various metal-metal joints to prevent seizure by corrosion. So I duely applied some ordinary lithium-based grease to the seatpost. I found it slips down under my weight on bumpy rides, so cleaned it out with white spirit and tried again using copper-based grease. Again it slips down all the time, no matter how tight I do up the seat-post quick release.

Now, I am a big chap admittedly, but this isn't supposed to happen is it.

Should I just clean out all the grease and leave it dry, or is there an alternative that will both stop any seat-post corrosion and prevent it slipping down into the tube?

I'd leave it dry. You'll be adjusting it up and down fairly regularly anyway so it shouldn't get a chance to seize up. If it does, sounds like you'd only need to bounce on it a few times to free it off. :D

I have always found rust to be a very handy antislip agent
and use it liberally on my bikes !!

Also very very cheap and provides a very good excuse not to
use the bloody thing in the first place
Much less tireing

Hope this is of help

P.S. Red paint will also do the trick

As Matt says, unless it is a very tight fit, I wouldn't grease it, just the quick release mechanism.
If found, please return to the pub.

As already suggested, I would also leave it dry.

However, I have read that the reason for greasing a seat post is not to prevent rust but to stop it breaking (and creaking). A standard seat post is not very costly, so I would place comfort first.

You might also think about changing the clamp if it still slips.
