    Quick question guys when fitting titanium bolts is there a special grease that's needed? Am sure I read somewhere about a certain grease for ti bolts!

    I use anti-seize copper paste to prevent galvanic corrosion on Ti bolts.

    Pro Bolt also include it with their titanium nuts.

    On disc bolts?

    I know they include it, which I find slightly bizarre as sure the notes contained within recommended thread locking them?

    These were sprocket nuts that were self locking anyway so copper paste was used.

    For Ti disc bolts I'm unsure whether one would use copper or threadlock as I've heard the corrosion is pretty bad and to remove a corroded Ti bolt would be a PIA?

    Don't know if there's any potential for corrosion due to two differing metals, but isn't galvanic corrosion something to do with electrical contact?

    Regardless, agree would be a real ball ache if expensive Ti kit is ruined trying to remove them.

    I've still got some Ti rear disc bolts to fit, just grabbed the booklet that came with them.

    Lol, that's absolutely no help!

    This is ref disc bolts though

    I read this as anything other than disc bolts should have anti seize on?

    As far as I was aware galvanic corrosion when two dissimilar metals are in contact, they corrode and fuse together.

    Regarding the disc bolts, i used anti seize to be sure on my Ti bolts on the discs, and i need to recheck the torque tomorrow as I have only just used the bike as there was a break in the weather today.

    Still none the wiser even though much of my research lead me to use anti-seize on titanium....

    Yeah mate, I've just read up on galvanic as wasn't sure and your right- apologies.

    Really not 100% sure, so like the OP I'd like to know!

    Where's Arthur? he'd know for definite.

    Ti does not corroded . Aluminium an steel corroded when bolted or used together .

    Ti probably won't on your bike... but the bike will suffer...

    Any two metals with different electrochemical potentials will cause corrosion... Titanium should corrode less than stainless steel but more than silver. Both of which are less than iron/steel. If in electrical contact with iron therefore the iron will corrode BEFORE the Ti (The Ti is essentially using the iron/aluminium of the bike as a sacrificial anode...

    You need to either electrically insulate it, or bolt on another sacrificial anode like a Mg or Zn block somewhere perhaps..
