Bontrager carbon carbon seat post with the metal saddle plate. The saddle plate is twisting -moving left and right- within the carbon seat post. I cannot see any adjustment to tighten or how the metal plate is attached to the carbon shaft. It appears that maybe the metal saddle plate is just glued into the carbon shaft of the post. I can move it about .25-.50 inches with my hand. This .25-.50 inches is greatly exagerated when the saddle is attached. 2004 Trek 5000 is three years old now. Planning to ride a big ride in the morning...movement started a week ago and I thought it was just tightening a screw...not the case. Anybody know what's happening here? Thanks.
