A CF seatpost will do very little to reduce road vibes. A better option would be to take a bit o' air out of your tires.josh51699 said:Looking for a Carbon Seatpost to take some road vibration out of the ride...I dont need the Mega Whammy deluxe, just a good solid good value for your money kinda thing. Sorta like the 04 Trek 1500 it will be going on.
The scientific data says that anecdotal reports of RBR posters are clear. CF posts dramatically lower vibration for some people, and make no difference for others. IME, when you have this kind of situation then the question is wide open, perhaps dependent on the specific post, the length of the post out of the frame, the weight of the rider, the setup of the rest of the bike, and (perhaps most likely) the desire of some people to experience an improvement contrasted with the skepticsm of others.josh51699 said:Never knew that, I was always under the impression that it did reduce vibration. So what is the disadvantage to lowering your tire pressure? I keep mine at around 110 which isn't too terrible high.

Maybe tubulars aren't such a PITA after all...Kerry Irons said:Lower tire pressure raises the risk of pinch flats
Wouldn't that depend on the specific design of each post? The type and density of the CF, how it is layed up, wall thickness, etc. would all determine which specific post was stiffer than the other.kronicade said:Isn't carbon stiffer then aluminum?
Something can be stiff and still damp vibration, or be very flexible and vibrate a lot (like a spring). These are different properties.kronicade said:Wouldn't a stiffer post create more vibration?
