I'm having a very difficult time finding a seatpost where I can adjust the tilt so that the nose of the saddle points more downwards than level. I've tried VO, Salsa Shaft, a vintage Specialized and a Ritchey. The nose of the saddle and the rails under the saddle are perpendicular to the floor for all of them.

Is there a seatpost that actually allows the saddle to point downwards?

I don't understand why all these seatposts allow so much titl for the saddle to point up... Surely more riders would prefer my preference if anything as to provide relief...
