You are right and thanks to Puget Pounder for asking for pics. That got me thinking that maybe it is adjustable. I took my seat off the post, took the pictures per request, and then started to loosen the two screws more so that I had a lot of play. The mechanism that felt stationary was stuck in place but with some work I got it to move. Not the easiest clamp to work with but it will do for know. Got the nose down a wee bit which improved my ride but then I found another problem: my handlebar is too low. For greater comfort I plan to raise them up a couple of inches. That should be a challenge. So thanks for all the good advice and in the future if I need a seat post I now have several good ones to choose from.
