Is is possible? Its a steel frame. I'm using a 26.4 post now, and I have to crank the bolt down pretty good. Would a 26.8 carbon post fit?

Or could someone point me the direction of a 26.4mm ti or carbon seat post.

In a word: no.
In more than a word:
IF you were using an aluminum seatpost, you might squeak it in, but carefully, and with some grease.
With a carbon post, it must fit exactly.
Too tight, and the failure of the post will be compressive. Too loose, and you will bite into the post with the seattube and crack it in half. Most manufacturers of carbon seatposts and bars don't recommend the use of shims either.
Just don't do it, and save yourself some pain later.

Thats what I thought, and told the guy, but he wanted us to look into it. So, anyone know where I could pick up a ti or carbon post in 26.4? He's dead set on carbon or ti. Tried talking him out of it, but you know how those guys with deep pockets are...

Now that I think about it, I've been looking for something in 26.4 for myself as well. Doesn't need to be carbon or ti, but nicer and lighter than the kalloy one I'm riding now.
So.... What would you guys suggest. Something light, attractive, and in 26.4. I used to see thomson elite in 26.4, but can't seem to find them anymore.

Hey, if Ti, then just get a 26.8 and have a machine shop turn it down to 26.4?
Might be possible, and lighter, too!

Seriously, no idea where to get a 26.4 made from these 'exotic' materials. Good luck.
