BTW: The Miche post clamps the saddle in the fore/aft position independently of the tilt. A nice feature to allow independent adjustment.
It is accomplished with a hook feature on the front of the uppler clamp as described above. Placement is like a hinge from the front to the back. Tightening is accomplished with a grub screw that has a conical point. As you tighten the screw it impinges on a ramp on the lower clamp that increases the clamping force.
