Very similar to the Zeus 2000 micro fluted seat post also listed on VeloBase, but this one has some differences in the clamp bolt area which appears to be done to reduce manufacturing costs.  Not sure if this post was produced at the same time as the 2000 version, or if it was a 'hand-me-down" from the 2000 line later.  Available in a wide range of sizes from at least 25mm up to 27.2mm or better.
