Road Cycling - grease?

Hello!
I have a Ti bike and a Chorus Ti seatpost. I took my seatpost out yesterday and found that the store I bought it from didn't put any grease on the post at all. From searching the forum I've found that a copper based grease is the right stuff for a Ti on Ti setup, but I'm having a hard time finding some other than the "Ti prep anti-size compound" found in a small syringe at the LBS for big $ for the amount you get. Anyone know of any alternatives?

Cheers!

Hi LSR

I think you would be able to use any copper loaded grease, usually called "anti seize" compound. A brief search on Google showed bunch of references to automotive & motorcycle maintainance - An auto parts store is probably a good place to start, and likely is cheaper than the bike branded stuff you mention. Sometimes I am very skeptical about the "snake oil" products in bike shops.... :)

Cheers,

Ed

I'd look for it on line. from what i understand "ti prep" is the exact stuff you need. using something else would be an unnecessary risk.

A product called Copaslip is what you need. Any auto shop will have it probably foraround $2 for a small tube which is more than you'll need.

PS: It is'nt necessary to grease a Ti on Ti interface because there is no ion xchange between the two surfaces so no corrsion will take place. But grease it with Copaslip if you want to feel more comfortable about it.

TimB, I think you are wrong. I have heard of ti-ti surfaces getting stuck

I don't mean to highjack this thread but I havn't seen or encountered greasing seatposts...

What is the grease for? lubrication? prevent entry of water? prevent freezing(this won't apply to me since it doesn't go below 20deg C here)?

If this is the case, should I grease my seatpost as well? I have a Al-Al surface, Al-Steel, Al-Ti....

Thanks...

The grease is to prevent the seatpost from seizing in the seat tube. I think it is a galvanic reaction that causes this to happen. The only seatposts I've heard of that should not be greased are the ones made of carbon fiber. With CF there is no danger of seizing, and the grease will only make the seatpost slip into the seat tube.

Phat man,

Yes you correct, i'm not entirely correct with what I said. There are instances where there has been stiction between T-Ti mating components.
Usually this occurs with screw threads hence it's not a good idea to use Ti screws in aTi frmae unless you grease them. The reason is the Ti Oxide layer although strongly bonded to the Ti substrate, is very soft and in a screw when there is lot of radial and angular movement the oxide rubs off and you you get stiction.
No with a seat post there should not be a problem provided the initial fit is quite loose so that moisture csn get between the two parts. Moisture is apparently one of the best lubricants for Ti-Ti interfaces.

That said, perhaps LSR should still use Copaslip on his post. :-)

thanks.... i just did...
