what anti-seize for ti stem in steel steerer
 

what anti-seize should i use for a titanium stem in a steel steer tube? preferably avaliable online.

thanks.

I use Ti prep (copper based anti-seize) is what I use on any ti fastener.

Get either Cu or Ni based Never-Seez at any auto parts shop. You will get 10 times as much for about the same price and can use it for other jobs and share with a lot of friends. The "Ti-Prep" sold at bike shops is the exact same thing repackaged at a huge mark-up.

+1 +1 +1. I also go to the auto parts store and get a tube of Permatex anti-seize.

I agree with obtaining your Ti-prep at the auto parts store.

But, I'm not sure you should be putting anything on the stem-steerer interface. Ti-prep is really a type of lube. I've always been told that lubes are a no-no at the stem-steerer interface.

Not correct. You shoulld always grease the quill and the inside of the steerer tube to avoid corrosion which can freeze the stem in the steerer. Greasing this interface is just like greasing a seatpost and for the same reason. Anti-seize is really not needed but is effective.

Maybe we're talking apples and oranges. When you say "quill" I'm thinking "threaded headset" and I agree with you.

But for threadless, I don't think so. All of the manufacturer's literature I've read says that the stem/steerer interface should be absolutely clean. No lube of any sort.

The OP didn't say which of the two he was referring to and I assumed threadless.

Bob

P.S. After re-reading the original post I see he describes it as "stem in a steel steer tube" so it sounds like he is referring to a threaded headset.

I got Ti-prep free with an order of Ti and Al hardware so I have not had to pay for it yet :)

Yeah, that was exactly the wording that made me believe it was a quill stem. Also, there were several makers of Ti quill stems and I don't know anyone making Ti threadless stems so that was further evidence.

I agree about installing a threadless stem dry, particularly if the steerer is carbon.

Moots makes 'em. Only $375.00....;)

Dean makes one for half that:

Other than that I agree with everything in this thread. I use that Permatex stuff for all bike, car and motorcycle applications and anything else. Grease a quill stem (assuming you want to move/remove it at some point), don't grease a threadless...

Manufacturer's like to make a big deal out of making a different anti-seize for every metal - but never say what you do when mating dissimilar metals. I think it's all marketing BS. I've never had a problem with that permatex stuff - even when bolting together the cast-iron exhaust manifold on my Alfa Romeo using brass bolts with stainless nuts and washers!

there's also the cinelli grammo. they made a threadless version as well as the quill.

my question is really just what anti-seize to use for any titanium anything that is being installed in steel. (not really specific to the stem.)

i asked about this only because of the whole titanium & steel thing as i haven't used any ti parts before on my steel bikes.. and i remember hearing that you have to use anti-seize for ti->steel.

by the way i am talking about a ti quill stem. i always have just used normal grease on steel/aluminum quills, and i wasn't sure if there is a difference when you've got a titanium one.

i wonder if the anti-seize would work better than normal grease for a stubborn old steel/aluminum expander stem that always gets stuck even when greased?

by the way i got a tube of the permatex anti-seize at the auto parts store.


the grammo threadless:

I stand corrected. OUCH.

I think you are correct and the composition of the anti-seize doesn't matter for most applications. I use the silver version of Never-Seez because that's what I have on hand for installing sparkplugs (steel threads) in aluminum heads and have had absolutely no problems removing them 30,000 miles later.

Compared to automotive and many industrial demands, bikes are extremely low stress service for any oil, grease or anti-seize.
