Low milage seat post, approx. 500 miles. Low milage because it creaks from the saddle clamp with my Avocet saddle. When installing the Avocet, the rails don't sit down into saddle clamp grooves the way they should. The seat posts top and bottom rail clamps match up perfectly to one another, but not to the Avocets rails.
I don't have any other saddles to try but my guess is that if a different brand of saddle used it will be quiet. Please let me know if you feel lucky.
