Seatpost confusion

My cyclocross bike has one of those seatposts that has a metal cylinder at the top of the post. I have yet to figure out how to make it level out my saddle. Is this as terrible a design as it seems or it is a better design that I just don't get? Hoping to get some advice before I go out and buy something I know how to adjust.

Avenir 200 series. Tried to find a good pic of one but none show the "cylinder" that the bolt threads into.

Lossen bolt, adjsut seat, tighen bolt.

Sorry, couldn't resist. That it a one bolt adjustment, lossen the bolt until every thing is loose, but don't remove it completely. Then you can adjust the tilt, and fore and aft. Tighten the bolt and your done. If you just want to adjust the fore and aft, you don't have to get it as loose as you do to adjust the tilt.
I much perfer these against the two bolt design, these are much easier to adjust. IMHO.

Exactly what I tried. There doesn't seem to be much if any movement available on the top part of the post. I much prefer the one bolt micro adjust on my Masi.

You might need to pop the adjustable bits loose after loosening the single bolt.

I greatly prefer two-bolt posts so that saddle tilt can be subtly tweaked.

A friend's mtb has a post like that. It took a while to get it free move move but once we got it loose, adjustments were easily. I think it was meshed to the radius a bit as another person posted. Stop by the LBS you bought it from for some help.

Fully disassemble and break the parts free: (1) Post/base (2) Lower clamp (3) Upper clamp (4) Bolt (5) Cylindrical nut. Reassemble and adjust while loose. You likely have (1) and (2) stuck together. PG

Eureka! That's exactly the problem. I popped the bottom bracket from the post and now everything works and makes sense. Thanks.
