will a titanium seat post make a difference in damping road vibrations as opposed to aluminum? might you actually feel a noticeable difference?

thanks.

But you'll gain style points.

dropping the rear tire pressure by as little as 5 psi will make more of a difference. or just replace the rear tire when its next due by 1 size larger (ie 25c instead of 23c). both will smooth things out for you in a far more sensible and proven fashion.

i like my Ti post but i dont think it makes a difference in ride quality that i can discern.

It can on a mtb or compact style road frame where a lot of seatpost is exposed. The Moots ti post is quite popular with mtbers for this reason--check the reviews at mtbr.com. But on a typical road bike with a horizontal top tube there isn't much post exposed.

Sheldon Brown on the topic:

"The only place that frame flex can be reasonably supposed to contribute anything at all to "suspension" is that, if you have a long exposed seatpost that doesn't run too deep into the seat tube, the bottom end of the seatpost may cause the top of the seat tube to bow very slightly. Even this compliance is only a fraction of the flex of the exposed length of the seatpost."
