My new Jamis Aurora has an awful seatpost. It is a Ritchey Road, 300 mm X 27.2 mm with cromo seatpin, black.

It has got to go. I've made several attempts at riding today and EVERY time I get on the seat does this little creek and then the nose jumps up and the back drops low. It doesn't matter how tight you get it, it goes out of position.

I don't like the way it adjusts anyway. One screw does everything. I must replace it before I can ride again. I'm out of patience.

Recommendations? It has a pretty good setback, so I will need another one that same style. Did I mention how aggravated I am!
