question about carbon seatposts.... I think I want one :)

[VeloVT]

Also, before you invest $$$ in a carbon post, make sure you've done a good job researching both weight and adjustment mech on your chosen post. Some of the carbon posts are not all that light (over 200g) but are still $$$$ because they are CARBON. IMO don't spend the $$$ unless it's lighter. Regarding adjustment mechanisms -- it seems like the majority of carbon posts use one-bolt systems. There are well-designed and easy to adjust one-bolt systems out there, but the majority of them leave something to be desired as far as tilt-adjustment is concerned (and sometimes other things -- I once had a one-bolt seatpost for which you could ONLY adjust tilt by simultaneously adjusting fore-aft. BAD!). Make sure you either see the post before you buy it, or at least order something from LBS that they have seen & used. If you can find a two-bolt, light carbon seatpost that's in the budget, go for it (a lot of these are $$$$$$$$$$$$$$$$$ -- I think the Campy Record post meets all of these criteria, for instance).

Personally I'm a big fan of Thomson (aluminum) posts. Super easy to adjust and in the weight range of a lot of carbon posts. And no worries about over-tightening. But bf has a Bontrager carbon post (not sure what grade, race x-lite maybe?) that came stock on his 2007 Madone 5.2, and the one-bolt mechanism is very elegant and easy to use... No idea what it weighs or how much it costs though, and this would affect my decision if I were buying it after market.
