Ok, this is going to be vague... What are those seatposts with like 3 or 4 holes near the top of the post ? I think they come in various colors, slightly laid back also, I've seen them somehwere but can't remember. Help ?

Oh by the way, what's up with the naked chicks on bikes when you Google "Seat post" ? http://images.google.com/images?q=se...n&start=0&sa=N
