I have the old style layback seat post. It seems with standard saddle rails that the trays or whatever they are called come together at max tightness and do not hold he saddle rails tight enough so it creaks occasionally under pressure.
I have thought about taking some beer can aluminum or something and try to shim the rails so they have a slightly greater diameter and are fastened better.
Seems like a hack. Has anyone solved this already.
