I have a Selle Italia Trans Am XO saddle (alloy rails) mounted to a Campagnolo Record Carbon Seatpost (aluminum clamp) The saddle is level and within the straight part of the rails, but is squeaking like crazy. The clamp is more than tight enough. I never had this problem with my old crappy Performance carbon post. It sounds like it is the saddle itself and likely not the post, and has only occurred since I fitted the new post. Is there any way to remedy this?
