Yes, use anti seize paste where another metal touches titanium.
No aluminum? How about head cups?

PLus BB cups, FD clamp, seatpost and so on.

Yes I was aware of those points but it does clear it up. Has external headset most of the bikes these days do not but can I assume that is a good thing? Certainly no press fit BB s for me

I don't expect it to have magic riding qualities but hoping it will be even soother than my CF. I remember my old steel Schwinn Traveler fro about 1991 was aqua green. Frankly road pretty good much better than any Al bike. Not as cutting fast and nimble as my CF but not harsh.

The whole Ti frame is different in Geometry so I wonder how that will be.


Middle of the road. He felt strongly about it.

??? I'll assume SOL means "Sh-t Out of Luck". Right? Anyway, if you bought the Colnago bike NEW, as you state, why couldn't you get warranty work on it? Most warranties are for the original owner. And extend for years/forever if its a manufacturing defect. Why didn't you just take your bought NEW bike back to the shop and say give me a warranty replacement? It sounds like truth and your stories don't add up correctly.


That was a misprint. I did NOT buy it new. In fact, I don't think I've ever bought a new bike frame.

Andrew - what do you think of anti-sieze in a bottom bracket?

Titanium is quite far down the galvanic tables and generally speaking
tends to become the cathode (most protected) part of a galvanic
corrosion circuit. The Anode (least protected) is the part that is
eroded away.

The logical thing to do is to protect any major or long term threaded
parts with a anti seize of some sort. I have installed stainless parts
into aluminum a famous corrosion sandwich in the presence of an
electrolyte), using an anti seize, and removed them several years
later with no evidence of corrosion.

John, you said you were accredited at welding titanium. As I recall you weren't supposed to lift off a weld and then restart immediately. You were supposed to let it cool down first. On the original ti frames you could see this because they always had to reposition the frame in the welding stand. But now that they grind the welds down smooth you can't see where to watch for problems anymore.

For threads or press-in against titanium it's standard
practice and highly recommended.

"in" a BB, used as a lubricant for bearings? That's dumb,
don't do it.
