This is the latest chapter in my pursuit of a seatpost that stays in place and is quiet and is directed more to Dave. After a couple of months of use the Deus XC post is popping and has lost some of the coating, making me think the O.D. has changed. I applied an anti-seize paste to it (Permatex) and the popping stopped but I now have slippage but not as much as I did with the Thomson post and Mobil 1 grease. My theory is the noise is caused by motion between the post and seat tube I.D. and the lube quiets this rubbing. Is there a lube that will quiet things but not reduce the coefficient of friction enough to prevent retention? As a footnote: all the wierd things that can happen to a machine happen to me so this is not an unusual situation for me.

We got ours through Ochsner Intl in Chicago. Your shop can get it for you. I will add an item number here to make it easy to order..

Yet another update - I got my paste through my LBS here in Minneapolis and the stuff works! I would never have guessed that a paste like liquid could prevent a seatpost from slipping. Thanks for the suggestion Dave!

I am resurrecting this thread because I recently went through the same troubles. My Thomson seatpost started slipping. I cleaned the seat tube and the seatpost and applied a light coating of grease, just like on every other bike I have owned. The seatpost still slipped, so I tried torquing the seat post clamp a little more. I pulled the threads out of the nut. I took the clamp apart to see if I couldn't find another nut and I noticed that the bolt had been turning against the bottom of its hole. I don't know if that had anything to do with the stripping of the nut threads or not. I chased the hole all the way through the other side of the clamp and found another nut. My clamp now works like a champ - it just looks a little shady.
Has anyone else had similar problems?
I ordered a WOODman Death Grip clamp in the 29.8 mm size after two guys at my LBS (in Germany) told me that I should not use a 30.0 mm clamp. My feeling is that 0.2 mm isn't enough of a size difference to cause a problem.

I've had three Gunnars, and everyone featured a slipping seat post and chippy paint. I can't do anything about the paint, but on all the bikes I finally just shimmed in about a 1" wide strip of Coke can to stop the slipping.

I've tried different posts, different clamps, grease, no grease, chalk, dirt, etc. The Coke can works best. I guess Pepsi might work as well, but I wouldn't risk it

Hi!
After experiencing slippage, I've used a thin layer of tooth paste with great success. Does anyone think there is reason to fear that the tooth paste might be corrosive?
