Ti frame / Ti Seatpin

marco007esq said:

I have read some places that using a ti seatpin with a ti frame is a
bad idea, since the two pieces of titanium will have a tendency to
bond. But, I would imagine that with proper greasing, this won't
happen.

Anyone have any insight? Is it risky to use a ti frame with a ti
seatpin? Only risky if you have poor frame hygeine? Any thoughts at
all?

If you don't remove your seat posts often, use a good grade of anti-seize
such as Ti-Prep liberally. I remove my seat posts once a month or so, and
have used grease to keep everything oh-so-smooth.

I have three ti frames, all with ti seatposts, ti head steams and ti
handlebars. I haven't encountered any problems at all.

Try asking Mark Hickey of Habenaro Bikes, he should be able to help you.

What he said. Normally anti-seize is used when you have a
high-pressure ti-to-ti contact (like a ti bolt in a ti boss). But for
a seat post that's taken out at least occasionally I'd just use
grease. If OTOH the post may be left in for (literally) years at a
time without adjustment, anti-seize wouldn't be a bad idea.

I doubt that I could ask for a better authority on the subject than
Mark Hickey. Thank you!

There are probably dozens of people on this news group who have more
metallurgical knowledge than I do. All I have is about ten years of
anecdotal evidence. ;-)
