Is there a specific grease for titanium frames? I have recently rebuilt my road bike on a second-hand Seven Cycles Alaris titanium frame. I used a fairly standard hydrophobic grease throughout but I have been told I should use a titanium-specific grease. The bottom bracket is the only place that I can think of with threading in the frame. Is there such a thing as a titanium-specific grease? Any advice on this?

For titanium frames, it is best to use a copper paste grease. You need to do so anywhere there is metal on metal contact, especially if it is aluminum to titanium contact.

Normal grease is not enough to prevent the accelerated oxidation and bonding that occurs between totanium and other metals.
