Thomson seatposts are popular, and American Classic also has infinite adjustment.
Thx OL... the Thompson looks nice. I would have never thought of the pop can shim.

I did try out my rubber shim today. I used a jar gripper piece out of my kitchen junk drawer. I only went around the neighborhood at a slow speed with no traffic. So, I felt ok about testing it.

At first, I was so happy. Without the groove issue, I got it to work! It leveled out beautifully. Instantly when I mounted to ride... Much better. But, it didn't stay that way. Lady bits started to get some pressure. When I got home, I thought I'm going to re-check the levelness. It shifted of course. Nose up (body weight on the back of the saddle).

Part of it I wonder if I didn't have it torqed tight enough? I didn't really want to on the short test ride to mark it up. But, I wonder with the single screw design, and one washer, in the oval slot... does that make it more prone to shift?

It would make sense I guess after looking at the other seat post, like the Thompson with a set of screws, vs my one.
