So I am replacing the standard crankset on my Litespeed with a compact crank. I have campy equipment, the old crank is a square taper and the new one is an ultra torque. Is there a specific grease or locktite that I should use when I thread the BB cups into the titanium frame? I've been using Park tools Polylube 1000 for lubing all the fasteners so far, but I am not sure if this would be a problem with dissimilar metals.

Thanks in advance

Ti prep and you should be fine.

Almost any thing that serves as a barrier between the two surfaces should work. I ride two Ti bikes year round in all kinds of weather. I've been using Phil Wood grease and have never had a problem.

Whenever dissimilar metals are involved, I use TefGel which is specifically designed to prevent galling and electrolytic corrosion in marine service, which is about as tough an environment as there is. I also use it on crank tapers and bolts as well as pedal threads. Highly recomended.

The only no no for grease is carbon fiber.

Now this looks exactly like what I am looking for, thank you.

Is Phil Wood grease similar to the Park Lube I mentioned? I'll look it up, and thanks for the suggestion.

Really, I had not thought about that. What do you use on fasteners with carbon fiber? (my other bike is a Specialized SWorks)

There is a special carbon fiber prep paste on the market. I have no clue what its made of. The only CF on any of my bikes is the fork on my road bike.

As far as I know fasteners holding carbon components do not thread into carbon fiber, they thread into metal inserts in the carbon fiber or through metal bushings, thus TefGel or similar would still be applicable. Those more experienced please correct me if i am wrong.

Found Ti prep anti-seize by Finishing Line on amazon. Works perfect and hopefully will prevent the galling that can occur between dissimilar metals.

Thanks to all.
